Creating Parts
In this tutorial, you create a chassis suspension component for an off-road
recreational vehicle. The part is an axle spacer. You create most of the features
of this part by first creating the basic shape. Then, you create separate parts
that you use as tools to add additional features to the basic shape.
Open the file spacer.dwg in the desktop\tutorial folder. This drawing contains
a fully constrained profile sketch of the basic shape of the axle spacer.
NOTE Back up the tutorial drawing files so you still have the original files if you
make a mistake. See “Backing up Tutorial Drawing Files” on page 40.
To create an axle spacer, you begin by extruding the part. First, review the
constraint system for this sketch.
To extrude a part
1 Use
AMSHOWCON to check the existing constraints.
Context Menu In the graphics area, right-click and choose 2D
Constraints ➤ Show Constraints.
2 Choose All.
Each arc uses the geometric constraints tangent and radius. The upper and
lower outside arcs are aligned using the X Value constraint, and the left and
right outside arcs use the Y Value constraint.
3 Press
ENTER.
Because this part is cast aluminum, you must extrude it with a draft angle.
Expand the part hierarchy by clicking the plus icon next to the part name in
the Desktop Browser. The Browser shows an existing part, SPACER, that con-
tains an unconsumed profile.
4 In the Desktop Browser, expand SPACER. Under SPACER, select the Profile1
icon. The sketch is highlighted.
