Working with Solid Models and Weldments - Autodesk Inventor 2010: No Experience Required - page 158

The buttons and boxes on the Shape tab ask you to select a profi le or profi les,
select a direction for the extruded feature to be created, and defi ne what size the
feature should be. If your sketch has only one viable profi le to be used for an
Extrude feature, it's automatically selected; Inventor moves on to prompt for the
remaining information.
Initially, you're offered the Join tool, which creates a positive shape in the
model. After your fi rst or base feature is placed, additional options are made
available in the dialog box:
Join This option uses the sketch profi le to add material to the model.
Cut This option removes material to a depth, to a plane, or through the
model, based on the sketch that was selected.
Intersect This passes the new shape through the existing shape. Only the por-
tions of the model that were common to both shapes remain.
New Solid This is an option for building multi-body features that are regarded as
separate from other features in the part. It's used for more advanced workfl ows.
More tab Switching to this tab allows you to defi ne a taper angle, which adds a
draft angle to cast or plastic parts.
Continue from where you left off in the previous section:
1. Set the Distance value to .5 , and use the Mid-Plane option to develop
the shape equally in both directions, as shown in Figure 4.3.

2. Click OK to create the disk-shaped feature.
