Example: Specifying Cap Angle and Closing Surfaces
This example shows creating a curve-driven solid tangent draft on one side of the sketched reference curve (1). In this example, the feature is added in Part mode.
1. Create a flat surface through the middle of the part, as shown in the following illustration.
2. Click Applications > Mold/Cast. The Mold & Cast tab opens.
3. Click Draft > Tangent Draft. The Tangent Draft dialog box opens.
4. To specify the Pull Direction, select the surface created in Step 1 and click Okay.
5. Select One Sided under Direction. Accept the other defaults.
6. Click the References tab and select the reference curve, then click Done.
7. Click under Parting Surface and select the surface created in Step 1.
8. Click . The tangent draft is created on one side of the reference curve, according to the Pull Direction, as shown in the following illustration.
9. Click the Options tab, type 30 in the Cap Angle text box and press ENTER.
10. Click . The system changes the angle of the planar surfaces (1) on both sides of the tangent draft feature, as shown in the next illustration.
Depending on your design intention, you may want the tangent draft to extend the complete length of the part. Then, instead of specifying the Cap Angle, click under Closing Surfaces on the Options tabbed page and select the two side surfaces of the part (1 and 2).
The resulting tangent draft geometry is shown in the following illustration.
 
* Depending on the draft line geometry, the system sometimes may not be able to extend it up to the closing surfaces. It is recommended that you use appropriate tools for creating and modifying curves to make sure that the draft line extends up to or past the intended closing surfaces, and then create a tangent draft.
