The Allow reduced angle check box is available only with Parting Line draft.
When you select this option, the draft angle on some portions of the drafted face may be smaller than the specified draft angle.

Use the Allow reduced angle check box under the following condition:
- The normal of one or more side faces adjacent to the edge and the faces being drafted is nearly perpendicular to the Direction of Pull. With this model type and condition, select the Allow reduced angle check box when the maximum angle between the pull direction and the normal of the steep face, plus the draft angle, is greater than or equal to 90°.
