Allow Reduced Angle Option

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°.
The vertical blue arrow represents the Direction of Pull (Top plane). The red arrow represents the surface normal at its maximum angle to the pull direction.

When the sum of the angle produced by the maximum angle and the Draft Angle is 90° or greater, select the Allow reduced angle check box to create the draft.

Draft applied (Draft Angle is 25°). The image above displays the same 25° draft applied. However, it is enhanced by applying an offset face and displaying curvature on the offset face.
In this example, the draft angle towards the narrow ends of the drafted face is reduced below the specified 25° to create the draft.
