Draft

Add draft to one or more faces of a part.

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 is needed.

Draft Along a Neutral Plane

You can use a reference plane or select an existing face in the model as the neutral plane.

  1. First, create a reference plane. Skip this step if you want to designate an existing face in the model as the neutral plane.
  2. 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.

    The guide panel appears.


  3. In the guide panel, select the Neutral Plane tab.
  4. 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.
  5. In the guide panel, adjust the Draft Angle.
    Note: To reverse the draft direction of a selected face, click Reverse Draft Direction in the microdialog.

Draft Along a Parting Line

You can select a line in the model to apply draft to the adjacent faces.

  1. Optional: First, create a line. Skip this step if you want to designate an existing line in the model.
