The sides of the object should not be parallel to the pull
direction (the direction in which the mold is pulled away from the object). Instead,
they need to be angled slightly so that the mold can be pulled away from the object
easily, without deformation or damage. This slight angle is called draft. The deeper the
mold, the more draft needed.
First, create a reference plane. Skip this step if you want to designate an existing
face in the model as the neutral plane.
On the Geometry ribbon, select the Draft tool.
Note: The tool may be hidden in the dropdown menu. To
access the dropdown menu, you can do one of the following:
Select at the lower right corner of the
currently displayed tool.
Click and hold the currently displayed tool.
The guide panel appears.
Choose a Direction:
Single (default): Create the draft on one side of
the neutral plane.
Both: Create the draft on both sides of the
neutral plane.
Symmetry: Create the draft symmetrically on both
sides of the neutral plane.
Select one or more faces to draft:
Next to Faces to Draft, click the
Select button.
Select one or more faces.
Note: To deselect a feature, hold down
Ctrl while clicking. To clear all selected
features, in the microdialog click Clear
Selection.
Designate the neutral plane:
Next to Neutral Plane, click the
Select button.
If you created a reference plane in Step 1, select it. Otherwise, select
an existing face in the model.
A blue arrow appears, indicating the draw direction.
In the guide panel, adjust the Draft Angle.
Note: To reverse the draft direction of a selected face,
in the microdialog click Reverse Draft Direction.
Click Apply.
