Pro/PROCESS for Assemblies

Using Pro/PROCESS for Assembly

About Pro/PROCESS for ASSEMBLIES

Use Pro/PROCESS for ASSEMBLIES to create assembly process plans and
serviceability documentation.

Specifically, you can use it to complete the following tasks:

• Define the steps of the assembly fabrication process.

• Create a manufacturing BOM for each step in the process.

• Regroup components independent of the design assembly to model the

fabrication structure accurately.

• Assemble tools and fixtures unique to a process step without affecting the design

assembly.

• Perform time and cost estimates for the assembly fabrication.

• Create detailed drawings of each step in the process.

• Customize the display of each process step by defining multiple explode states

with jogged explode-offset lines and by assigning different colors and line fonts to
components based on their status in the step.

To Use Pro/PROCESS for ASSEMBLIES

1. Click File > New to create an assembly process file.

2. Click Assembly and Process Plan.

3. Enter the name for the process plan.

4. To create an assemble step or general step, choose Sequence > New Step >

Assemble > Done. The Step dialog box opens.

5. To retrieve a model, click Add Model > Open.

When creating the first assemble step, you retrieve the model for the design
assembly to be fabricated. The design assembly appears on the screen in a
phantom line font. The process assembly references the design assembly for
placement of components and parameter information, but does not affect the
design assembly.

6. Select components to be assembled directly from the screen or from the Model

Tree. Notice that the line font of assembled components changes from phantom
to solid.

7. Define additional elements (such as, description of the step, a simplified

representation, explode state, and time and cost estimates) for defining the step.
Explode-offset lines, showing how components fit together, are created in an
explode state.

Pro/PROCESS for Assemblies Help Topic Collection

8. Click OK when all desired elements are defined.

9. Define additional steps by selecting New Step from the STEPSEQUENCE menu.

The remaining unassembled components are displayed on the screen in phantom
line font for selection during an assemble step. To show the status of components
being assembled and disassembled, add the Process Status column to the tree
tool.

10. While defining an assemble step, you can add additional fixtures and tools to the

process assembly without affecting the design assembly. Click COMP SEL > Add
Model. To place the fixture, use a drag and drop technique. To specify explicit
assembly constraints such as mate and align, select PACKAGE > Finalize.

11. To replay the steps, select Play Steps from the ASM PROCESS menu.

12. Create detail drawings of the process assembly by adding the process assembly

model to a drawing. After you add a model to the drawing, the Process State
dialog box appears, listing the steps in the process assembly. You can select the
desired step and a simplified representation or explode state, and then click OK.
From the VIEW TYPE menu, select a view of the model in the specified step.

13. Use Pro/REPORT to create a manufacturing BOM for the step, which lists only the

components assembled during the active step. The system lists a new set of
report symbols, beginning with a prs prefix, unique to process steps.

14. When you create a view of another step, set the current step by selecting

DRAWING > Views > Dwg Models > Set State. The system displays a dialog
box. You can select a new step from the list through this dialog box.

15. Select Views from the DRAWING menu, and then Disp Mode and Process

Disp to display components in different colors or fonts depending on their
process status (that is, previously assembled or currently being assembled).

Process Assemblies

Basics of Process Assemblies

About Process

A process is a Pro/ENGINEER assembly that contains the features defining the
process steps. It follows the naming convention process_name.asm. An assembly
process has dependencies on one or more design assemblies and fixture models. The
process object has a required (for Pro/PDM purposes) dependency on the assemblies
that are assembled into it. If you assemble a part by selecting it from an assembly,
the required dependency is relative to the assembly, not the part. However, if you
assemble a single part by selecting the part directly from its part window, the
required dependency is on the part.

A process consists of all referenced assemblies and parts, as well as the sequence of
steps that define the process actions: assemble, disassemble, reassemble, reposition
and other steps related to fastening, preparing surfaces and so on.

The system retrieves the process model in whatever state it exists before the start of
the process (that is, without retrieving any components and without an active step).
You must use the SET STEP menu to move to an active step. The system displays
only those components required by the indicated step.

To Enter Process Mode

1. To create a new process, click File > New. In the New dialog box, click

Assembly and Process Plan.

To open an existing process, click File > Open and select an existing assembly
process file.

2. For a new process, type the name for the assembly process file.

Pro/PROCESS for Assemblies

3. Select an option from the ASM PROCESS menu:

o Sequence—Manipulate a process step (add, create, redefine, and so on)

using the SEQUENCE menu.

o Component—Perform component operations using the COMPONENT

menu.

o Fab Unit—Create, modify, or delete fabrication units using the FAB UNIT

menu.

o Modify—Modify assembly or assembly component dimensions and features

using the PROCESS MOD menu.

o Simplfd Rep—Create, modify, or set simplified representations.

o Explode State—Create and edit explode states using the EXPLODE menu.

o Regenerate—Update modified part and assembly dimensions.

o Play Steps—View assembly at individual steps of the process plan using

the STEP REGEN menu.

o Relations—Add and edit constraint equations.

o Set Up—Set up additional process information.

o Layer—Perform layer operations.

o Program—Access Pro/PROGRAM.

o Integrate—Resolve differences between the source and target processes.

To Display Process Status

The system can display process status in the Info menu. Process Status describes
the current status of the process assembly. Components can be listed as:

• Assembling (assembled by the current step)

• Not Assembled

• Disassembled

Note: Repositioned or reassembled components are listed as assembled. Top-level
assemblies are listed as Design Only.

1. To display the Process Status, click Settings > Tree Columns.

2. Click column types from the left column in the box and move it to the right

column.

To Create and Modify Step Parameters

You can create parameters for individual steps. Parameters in individual steps are
similar to feature parameters—they exist for that step only.

1. Click ASM PROCESS > Set Up > Parameters.

Pro/PROCESS for Assemblies Help Topic Collection

2. The Parameters dialog box opens. Select the step from the list in the dialog box

and click OK.

3. Click

to create step parameters or click column headings to modify specific

parameters.

To Set the Display of Process Components

The display of components in an assembly process can be set based upon their
status in the assembly process. When a component is at a particular status, its line
style will change. Using alternate line styles for displaying components as you create
your assembly process can help to differentiate one component from another.

1. Click View > Model Setup > Process Display to open the PROCESS

COMPONENT DISPLAY dialog box.

Here you can modify the display method used for the different status levels of a
component in your assembly process.

2. Set a line style for components at each of the following status levels:

o Previous Components—Components in the process that have already

been assembled as part of an existing step.

o Current Components—Components that are active in the current

assembly step.

Using 3-D Notes with Process Steps

The display of 3-D Notes depends on the display of the step to which the note
belongs. When a step is active or is being used in a drawing step, the system
displays a 3-D note created for the step. When the step is no longer displayed, the

Pro/PROCESS for Assemblies Help Topic Collection

note also disappears. Creation of 3-D notes is the default when creating a note in a
step.

3-D notes can be displayed by selecting them from the screen or from the model
tree. They are displayed only when their step is active, even if their status in the tree
is Shown. You can erase only the 3-D notes that belong to the active step.

Creating Different Types of Process Steps

About Process Assembly Steps

Process steps describe the actions used to assemble the product. You activate a step
by selecting it in the Process window. You can only have one active step at any
time. The graphics window displays the assembly in the state created by the active
step. Process step types are: Assemble, Disassemble, Reassemble, Reposition, and
General.

Assemble Step Type

About the Assemble Step Type

Pro/PROCESS for Assemblies

Use the Assemble step to assemble parts, entire assemblies, and individual
components from reference assemblies into the process assembly. You specify the
component type prior to the selection process.

If you are assembling individual components from an assembly, you must place
them in the process assembly if they are the first ones being placed from that
assembly. This step type adds a new occurrence of the component to the BOM.

To specify the reference components, you select them from a model window. The
last model window that you used to select components is the active window. If the
object in the active window is an assembly, you must specify the components in the
assembly to be assembled in this step.

You can also specify components to assemble by selecting them in an already
partially assembled reference assembly that has either not been assembled yet, or
has been disassembled. When you select components in the process assembly, the
system turns on the display of those components. If you have added components
without retrieving a reference assembly', use the tree tool the logical view of the
process assembly to choose the components.

If you activate a model that is already partially assembled in the process, you can
choose to assemble a new occurrence of the top-level component or continue
assembling components from the already assembled occurrence.

If a simplified representation of the process assembly is active, you can assemble a
simplified representation of another assembly or part into it using the SELECT REP
menu. This is similar to the functionality in Assembly mode, where you can assemble
a simplified representation of a component into a simplified representation of the
top-level assembly.

Using the display_comps_to_assemble Configuration Option

You can use a configuration option display_comps_to_assemble to enhance
performance when working with complex assemblies. When you set this option to no
(default is yes), you can select design assemblies and components from the Model
Tree without displaying them on the screen until they are selected.

If no geometry exists in the process assembly (no features or components are yet
created or assembled, or all components have been disassembled), the system, the
system places the component being assembled in the default orientation and location
(similar to assembling the first component of an assembly). If geometry exists, the
system provides the Package functionality to enable you to place the component.

To Create an Assemble Step

1. Click ASM PROCESS > Sequence > New > Assemble > Done.

2. The Assemble dialog box opens. Define the elements in the dialog box.

General Step Type

About the General Step Type

Pro/PROCESS for Assemblies Help Topic Collection

You use the General command in the STEP TYPE menu to create steps for
miscellaneous operations such as painting, cleaning, gluing and so on. Process steps,
similar to features, consist of a set of elements and can have geometric references.

To Create a General Step

1. Click ASM PROCESS > Sequence > New Step > General > Done.

The STEP: General dialog box opens. Define the Type element by selecting from a
list containing all default types as well as any user-defined types that exist in the
current model (Caulk, Clean, Drain, Fill, Inspect, Lubricate, Paint, Torque, Verify).
Click Done. If you select New Type, all elements reset to default values, and you
must enter the name for the step.

2. Define any optional elements in the dialog box.

3. Click OK.

Reposition Step Type

About the Reposition Step Type

Using the Reposition step type, you can reposition a previously assembled
component in the process assembly. You select the component from the process
assembly and move it using the Package functionality.

You can only select components that are currently part of the process assembly. If
you pick a component that is part of a fabrication unit, the entire unit is selected.

To Create a Reposition Step

1. Click ASM PROCESS > Sequence > New Step > Reposition > Done.

2. The STEP:Reposition dialog box opens. Define the following required elements:

o Components—Select components for the process step (standard

components, fabrication units, cable features, pipe features, weld features,
tools/fixtures, and bulk items). You pick the components from the process
assembly. You must choose at least one component to create a valid
reposition step. You can only select components that are currently part of
the process assembly.

o Position—Reposition selected components using the Package interface.

This defines the transformations for the components. Only components
defined by the first element may be repositioned. Only one Package
operation is allowed per step. All of the components will be repositioned
together.

3. Define any additional elements.

4. Click OK.

Disassemble Step Type

Pro/PROCESS for Assemblies

About the Disassemble Step Type

Use the Disassemble command in the STEP TYPE menu to disassemble components
that are already assembled. Select components from the process assembly. If you
want to move the assembly to a different work cell or fixture, you can disassemble
all components. Disassembling a component does not remove the model from the
process assembly.

To Create a Disassemble Step

1. Click ASM PROCESS > Sequence > New Step > Disassemble > Done.

2. The Disassemble dialog box opens. Select components to disassemble. You can

only select components that belong to the process assembly. If you select a
component that belongs to a fabrication unit, the entire unit is selected.

3. Define any optional elements.

4. Click OK.

Reassemble Step Type

About the Reassemble Command

Use the Reassemble command in the STEP TYPE menu to reassemble previously
disassembled components. Using the Reassemble step does not add another instance
of the selected model to the BOM. If you want to add another occurrence of the
component to the BOM, use the Assemble step.

You only reassemble components that you have disassembled. Therefore, only
components that have been disassembled are available for this step. Since you
assembled the selected components in a previous step, you do not have to specify a
component type. You need to reconstrain all components that you select for this step
using the COMP/FAB menu.

To Reassemble Step Elements

1. Click ASM PROCESS > Sequence > New Step > Reassemble > Done.

2. The STEP:Reassemble dialog box opens. Select components to reassemble.

3. Define any optional elements.

4. Click OK.

Fabrication Units

About Fabrication Units

Fabrication assemblies are representative of what is actually manufactured and
shipped. These assemblies differ from design assemblies in that they also include
components that are used for shipping purposes only, as well as components that
represent documentation and other support material. For example, a pipe assembly

Pro/PROCESS for Assemblies Help Topic Collection

often contains cap parts to protect the open-ended assembly from damage until it is
assembled into a higher level fabrication assembly.

With Pro/PROCESS for ASSEMBLIES, you can use fabrication units to avoid
permanently affecting the design assembly structure. You can create modify, and
delete information about fabrication units using the Fab Unit command in the ASM
PROCESS menu.

Fabrication units are groups of components that you use to create a process plan
showing the actual build Bill of Materials (BOM). They appear in the process BOM as
individual components.

You can use a fabrication unit as a component in an assemble step, which assembles
all of the components in the fabrication unit simultaneously. The system considers
them to be one unit for explode, simplified representations, Bill of Materials, and so
on. You can also select them for the other step types (disassemble, reposition, and
so on).

Pro/ENGINEER considers the groups of components comprising the fabrication units
to be one unit throughout the process plan, you should create them before you use
any of the components in a process step. You can create them even if some of the
components are already in the plan; however, you should redefine that step and
assemble the fabrication unit instead of the individual component. The fabrication
unit cannot include a component that is used in one assemble step and a component
that is used in another.

When working with fabrication units, consider the following:

• Fabrication units do not include placement constraints. The fabrication unit may

include components that have not been assembled yet; you add the placement
constraints for these components when you assemble the fabrication unit into the
process.

• A fabrication unit contains components from a single assembly in the process.

The components may come from multiple levels of that assembly, but there must
be a single assembly that ties them all together.

• You can have multiple occurrences of the same fabrication unit. If there is more

than one other occurrence, the system highlights them one at a time and asks
you to select one. The process BOM and parts list catalogs each occurrence of a
fabrication unit.

• Fabrication units are listed in the manufacturing BOM as a unit. However, the

BOM does not list all components that belong to that unit.

To Create a Fabrication Unit

1. Click ASM PROCESS > Fab Unit > Create.

2. Enter the fabrication unit name.

3. Retrieve the top level design assembly to define the fabrication unit.

4. The top level assembly appears in a phantom font. You can now select

components similarly to adding components to a process step.

Pro/PROCESS for Assemblies

Exploding Assemblies

Basics of Exploding Assemblies

About Explode Functionality

In Process mode (as in Assembly mode), you can create exploded states to define
the exploded positions of all components. For each exploded state, you can change
the explode locations of components, create explode offset lines, and toggle the
explode status of components. To access the Explode functionality, click View >
View Manager and click Explode.

You can define multiple exploded states for each assembly, and then explode the
assembly using any of these exploded states at any time. You can also set an
exploded state for each step of the process plan and each drawing view of an
assembly. The default exploded state positions each component based on its
placement constraints.

To create other exploded states, you position components using the mouse cursor to
drag components.

Using Offset Lines with Exploded Assemblies

About Using Offset Lines in Exploded Views

You can use offset lines to show how exploded components align when they are in
their final positions, and then modify or delete them when editing an exploded state.
They display in a dashed font. Offset lines are composed of three straight segments.
You determine the direction of the end segments by selecting references (parallel to
an edge or curve or normal to a surface), and the middle segment connects the two
end segments.

Configuration File Options for Offset Lines

In the configuration file, you can set the default color and font style for offset lines
created for exploded views. The following options are available:

• offset_line_def_font

• offset_line_def_color

Create Customized Documentation

About Drawing Mode With Process Documentation

In Drawing mode, you can create customized documentation for the assembly
process. You can add views for each step and control the display of a component
based on its status in the step. You can also create report tables using Pro/REPORT.

To create views of a process at a particular step, you must first select a process
assembly in session and then select a process step from a list. The system creates a
default view of the process at that step.

In Drawing mode, you can also do the following:

• Create an exploded state in the context of the drawing (if you have not already

exploded the process assembly at that process step, or if the explode is not
appropriate for that view). The system stores the explode information in the
drawing.

• Control how the system displays the components in the process assembly in the

drawing view. Click View > Drawing Display > Component Display to open
the MEMB DISP menu to define the display colors and fonts. For example, you
can display all assembled components in neutral gray, dashed font, and all
components that you are assembling in red, solid font.

To Create a View of a Process Step

1. In Drawing mode, click DRAWING > Views > Dwg Models > Add Model.

2. Select the process model. The Process State dialog box opens.

3. Using the Process State dialog box, select a process step, an exploded state, or

a simplified representation for that step.

Note: An existing drawing sheet can be used as a template to format new sheets in
a process drawing. The formats and views of the current sheet are used as a
template for a new sheet in the drawing.

4. Continue to define a view as you do for regular drawings.

To Control the Component Step Display

1. Click DRAWING > Views > Disp Mode > Process Disp.

2. The Component Step Display dialog box opens. This dialog box allows you to

determine component display status according to whether or not the component
is referenced in the current step. Change the display of the selected component.

Object Parameters in Drawings

You can use object parameters in your assembly process drawings as you would any
other object parameters. The object parameters can be used in drawing notes just as
you would with other drawings.

In particular, you may want to include the step description in your drawings. This
description can be included as a note which contains the following object parameter:

Pro/PROCESS for Assemblies

&description:FID_#

Where # is the feature ID for the step you are documenting.

Exploded Views in Drawing Mode

Modifying Exploded Views in Drawing Mode

In Drawing mode, you can edit explode positions and offset lines by clicking on the
VIEW MODIFY > Mod Expld. The system stores these changes in the drawing, not
in the assembly or process model. A drawing may use an explode state from an
assembly or a process.

The drawing references the assembly or process exploded state as long as the
reference is valid. The reference is no longer valid if you modify the explode from
inside the drawing. When this happens, the system copies the exploded state into
the drawing and removes the reference to the assembly exploded state.

To Modify an Exploded View in Drawing Mode

1. Click VIEW MODIFY > Mod Expld.

2. Select a view to modify.

3. Choose an option from the EXPLD STATE menu:

o Create—Create an exploded state for this view.

o Set Current—Set the current state as default.

o Copy—Copy an exploded state.

o Redefine—Redefine an exploded state. Choose Position to change the

explode positions, or Expld Status to change the exploded status.

Modifying the Explode Positions in Drawing Mode

You can use the Mod Explode command in the VIEW MODIFY menu to modify
explode positions. You can change the explode position of components and you can
toggle the explode status of components to be exploded or unexploded. Changes
made from this menu become part of the drawing; they do not affect the process
assembly.

Note: In steps that have components as references, you can control the display of
components based on their status in the current step using options in the DISP
MODE menu.

Using the Configuration File Options to Change Color and
Line Font

You can set the default color and line font for models in drawing mode. All options
are available as keywords in the configuration file. Color is user-defined by
percentages of red, green, and blue.

For previously assembled components in the step, set the following variables:

Pro/PROCESS for Assemblies Help Topic Collection

• prev_proc_comp_def_font

• prev_proc_comp_def_color

For components assembled in the step that is active in the current view, set the
following variables:

• curr_proc_comp_def_font

• curr_proc_comp_def_color

Create Reports and Tables

About Using Pro/REPORT for Assembly Process Drawings

There are special Pro/REPORT parameters that you can use to create a custom table
detailing the assembly process. An entire list of available system parameters appears
in the following table.

Parameter Name

&prs.step.type

Lists the methods of assembly being used
for each step displayed in your drawing.

Tip: User-Defined Parameters in Tables

An item's parameters can also be used in a Pro/REPORT table as a user-defined
parameter. For example, the COST parameter of a part can be used as a user-
defined parameter in a Pro/REPORT table as &prs.step.cost_estimate even though a
system-defined Pro/REPORT parameter called &prs.step.cost_estimate does not
exist.

Example: Creating a Report

Pro/PROCESS for Assemblies Help Topic Collection

When creating a report, it is important to consider the structuring of the symbols in
the report. Pro/REPORT parameters used in Pro/PROCESS for ASSEMBLIES are based
upon either the current step in the drawing or all steps in the drawing.

Pro/REPORT provides information based upon a hierarchy of specifications
proceeding from left to right. In the example, the parameter &prs.actstep.number
provides the step number of the step in your assembly process that is currently set
as the active model. Similarly, &prs.actstep.type gives the assembly method used
in just the active step. The parameter &prs.actstep.comp.name provides the names
of all assembly components used in the active step.

&prs.actstep.number &prs.actstep.type

&prs.actstep.comp.name

BASE

2 ASSEMBLE

8_PORT

2 ASSEMBLE

2_PORT

In this case, instead of using the parameter &prs.actstep.number, the
&prs.step.number

parameter is used. This parameter behaves differently than the

other. While the &prs.actstep.number parameter specifies the name of the step
number, the &prs.step.number parameter lists the step number for all models in
your drawing, regardless of which model is the current one. This parameter is used
to list report information for all steps in a drawing with multiple models. The same
principle can be applied to the other two report parameters.

Other Process Functions

About Working with Large Design Assemblies

There are a number of ways to work effectively with large design assemblies.

• Use simplified representations

• Retrieve the earliest step

Note: Retrieving the earliest desired step when retrieving a process assembly
limits the number of components retrieved into memory because only those
components required for the process step are retrieved and displayed. All
components of the design assembly are retrieved when adding a new step.

• Set appropriate configuration options

Pro/PROCESS for Assemblies

Simplified Representations

About Simplified Representations in Process Assemblies

Simplified representations are used to improve visual clarity and performance. They
are used to simplify the process assembly by excluding or substituting components
for all steps, or to simplify only the current state (that is, step). Simplified
representations of the design assembly can also be used when creating assemble
steps in the process assembly.

To Create Simplified Representations

You can define a simplified representation for a process assembly.

1. Click

or View > View Manager. The View Manager opens.

2. Click Simp Reps

3. Click New to create a new simplified representation.

You can specify a simplified representation for particular step while defining or
redefining the step.

1. While defining a step with the STEP dialog box, click the Simplfd Rep element

and Define.

2. The View Manager opens. Click New to create a new simplified representation.

Retrieving a Simplified Representation in a Process Assembly

You can define a simplified representation of the process assembly before adding the
design assembly to the process. Then, when you work with the process assembly,
you can use the View Manager to add a model to the process.

Note: Components excluded in the design assembly do not appear on the screen in
phantom line font but appear in the Model Tree of the assembly where they are
selected.

User-Defined Features

About Process User-Defined Features

You can create and store a user-defined feature (UDF) of one or more General
process steps the same way you would create a standard UDF in Part mode. You pick
the step(s) to include in the UDF, and enter reference prompts, variable elements,
and other data. With a license for Pro/PROCESS for ASSEMBLIES, Pro/ENGINEER
provides a standard library of common process steps:

• Caulk

• Clean

• Drain

• Fill

Pro/PROCESS for Assemblies Help Topic Collection

• Inspect

• Lubricate

• Paint

• Torque

• Verify

You can customize the library by adding your own steps or changing the definition of
the steps provided.

To Create a UDF

1. Click SEQUENCE > Step Library.

2. Group steps together into a UDF.

About Obtaining General Information

Using the Info command in the main View menu, you can access general
information concerning mass properties, Bill of Materials, measure, and so on. To
obtain process-specific information such as cost, time estimates, and component
usage lists, use the Process Sequence command in the Info menu.

The Information Window contains the textual information from the process sequence,
including the description and type of each step, all attribute names, and the
corresponding values.

Using these commands, you can access an Information window that displays the
complete process sequence. It includes information such as the step type,
description, all attributes, and their values. The system saves this information to a
file as it is displayed, so you can print it without actually stepping through all of the
steps.

BOM and Parts Lists

To show which components and tools are required to complete a step or group of
steps, you can create and export (to a file or print) a parts list based on Assembly
Status (current, previously assembled, and so on.) and Component Type (Design,
Fixture, Bulk Item, and so on).

You can use the following possible formats, and switch between them:

• Indented list to show hierarchy, as in simplified representations

• Current BOM format

• Flat list with no hierarchy, just a list of components

You can create the list based on a step or a group of steps. To create the list for a
list of steps, define the subset by entering numbers separated by commas or
hyphens.
