About AutoCAD Mechanical
AutoCAD Mechanical is a 2D mechanical design solution built for designers
and detailers who require high-quality drafted output with minimal effort.
Built on the AutoCAD 2002 software platform, the AutoCAD Mechanical 6
design software package includes:
■
AutoCAD Mechanical 6 with the power pack (2D Parts and Calculations)
■
AutoCAD 2002
The AutoCAD Mechanical software provides 2D mechanical engineering and
design tools, including:
■
Improved design and detailing tools, including cams, springs, holes, and
notes for holes and standard parts.
■
Improved workflow and compliance with company standards.
■
Intelligent production drawing and detailing.
■
Assembly tools for managing detailed 2D drawings and assemblies.
■
Standards based design and content, with more than half a million
reusable 2D standard parts, features, holes and structural steel shapes.
■
Machinery systems generators that speed up systems creation and reduce
errors.
■
Engineering calculations that provide greater accuracy.
■
Collaboration tools, including support for Autodesk Streamline.
■
Built-in IGES translator.
Modeling with AutoCAD Mechanical 6
AutoCAD Mechanical 6 software contains over half a million standard parts
with data that can be quickly incorporated into any design. These include
common parts such as predrawn screws, nuts, washers, pins, rivets, bushings,
rings, seals, bearings, and keys. AutoCAD Mechanical also includes 8000
predrawn standard features including center holes, undercuts, keyways, and
thread ends.
Object Oriented Construction
AutoCAD Mechanical 6 extends drawing objects to include contours,
centerlines, symbols, shafts, screws, and bearings. It is not necessary to
manually change individual elements of drawing objects in AutoCAD
Mechanical 6.
Modeling with AutoCAD Mechanical 6
|
5
AutoCAD Mechanical 6 automatically changes all the elements of an object
when an edit occurs. For example, if the nominal diameter of a screw
connection is changed, all elements of the screw connection (such as edges
and hatches) are recognized and changed automatically.
The use of intelligent objects in AutoCAD Mechanical 6, such as screw
connections, is an object-oriented approach to construction. This approach
makes it faster and easier to create mechanical designs, provides large
productivity gains during changes, and reduces the chance of costly errors.
Layer and Layer Groups
The layer system in AutoAD Mechanical is made up of working layers,
standard parts layers, and special layers. All layers perform specific tasks and
are recognized by AutoCAD Mechanical commands. For instance, contour
lines, construction lines, centerlines, dimension lines, and corss-hatching
lines are placed on separate layers. AutoCAD Mechanical creates layers in the
drawing when they are needed and allocates the object to the appropriate
layer.
■
Working Layers consist of the base layers and standard part layers. Working
layers are repeated in each layer group.
■
Special Layers are used for drawing borders, part references, construction
lines, and viewports. Special layers are created once for the whole drawing.
Special layers make a drawing more clear and speed up plotting.
■
Layer Groups are used to organize associated or related elements to a
drawing. A working layer and standard parts layer is created for every layer
group. You can create any number of layer groups.

Chapter 1
Where to Start
Linetypes, Lineweight, and Color
The attributes of lineweights, linetypes and colors in predefined layers are
defined by the standard set in the drawing configuration.
The AutoCAD Mechanical layer management system automatically
configures almost all drawing elements. Since the object attributes of almost
all drawing elements are configured with the ByLayer method, centerlines,
construction lines, hidden edges, and so on, are controlled automatically.
Dimension Styles
AutoCAD Mechanical 6 contains several dimension styles, which are applied
automatically depending on the function using the dimension style feature,
and the current standard selected.
Text Styles and Text Fonts
There are four text style formats available which have different text heights,
and alignments. AutoCAD Mechanical 6 offers font databases with a vast
number of special characters, such as the diameter symbol.
Scale Factors
The scale of dimensions, symbols, or hatches vary depending on the base scale
factor, the scale of the drawing border, or the scale area that is set in the drawing.
The base scale factor can be set in the Mechanical Options dialog box, or by
inserting a predefined drawing border for a new drawing. If you combine
several drawing borders to a file, each of the drawings can have a different
plot scale.
In model space it is easy to create multiple scale areas with different scale
factors. Each scale area controls the scale of text, dimensions, and symbol
properties regardless of the base scale factor of the drawing.
You can create viewports and assign layout attributes including scale factor
from the layout tab. It is also possible to create new viewports based on
existing scale areas in model space.
Rescaling Objects
If you determine that the format or the scale factor for a drawing border has
to be changed, AutoCAD Mechanical 6 rescales all affected drawing objects.
All texts, dimensions, and symbols, are automatically resized according to
the new scale factor.

AutoCAD Mechanical 6
Functionality Overview
AutoCAD Mechanical 6 extends the basic drawing, dimensioning and
documentation functionality of AutoCAD 2002. It provides features for
getting the most out of the intelligent standard parts in your drawing, as well
as engineering features for optimizing your design.
2D Standard Parts
To generate an object from scratch, use the parametrically generated,
intelligent geometry listed below:
■
Standard Parts contain more than 800.000 intelligent standard parts
including screws, nuts, washers, pins, rivets, bushings, rings, seals,
bearings, and others.
■
Standard Features contain 8,000 intelligent standard features including
slots, centerholes, undercuts, keyways, and thread ends.
■
Standard Holes contain over 20,000 intelligent standard holes including
through holes, blind holes, counterbores, countersinks, and others.
■
Standard Structural Steel Shapes contain over 44,000 intelligent standard
structural steel shapes.
Standard Part Tools
Almost more important than the standard parts are the tools designed for
them. After all, how often does a design call for a screw without an
accompanying hole? In AutoCAD Mechanical 6 these tools include:
■
A Screw Connection for inserting complete fastener assemblies.
■
Change Representation functionality changes the representation of your
standard parts (symbolic, simplified, standard).
■
The Power View function for deriving associative orthographic views, for
example, a side view of a standard part from a front view or vice versa.

Calculation Tools
AutoCAD Mechanical 6 provides the following tools for saving you time with
your engineering calculations, and ensuring you get the design right the first
time:
■
Cam Generator creates cam plates and cylindrical cams given input border
conditions. Velocity and acceleration, as well as the cam curve path can
be calculated and displayed. Driven elements can be coupled to the cam
and NC data can be created via the curve on the path.
■
Beam Calculation determines the moment of inertia and deflection of
beams.
Engineering Calculation
A mechanical design includes more than just proper fit and form. It also
includes proper function. Ensuring proper function requires incorporating
Engineering know-how. AutoCAD Mechanical 6 provides these additional
tools for calculations:
■
Shaft Calculations include the deflection line, bending moment, torsion
moment, supporting force, torque rotation angle, equivalent tension and
safety factor for shafts with regards to influence of notches and dynamic
load according to DIN 743 and ANSI.
■
Screw Pre-Calculation selects the right size screw based on given forces,
materials, and methods of tightening.
■
Bearing Calculations select the right bearing based on load and life ratings.
■
FEA for determining the resistance capability of an object put under a
static load. This function allows you to add movable and fixed supports to
the part to be analyzed and also enter stress points, lines, and areas.
■
The Screw Calculation gives the designer a tool to check a screw
connection. As a result it calculates the different safety factors. The
designer can calculate high duty bolted joints with one screw.
