Example: Creating a Curve-Driven Tangent Draft
This example shows how to add a 15-degree tangent draft on both sides of the parting surface (1). You can use any type of curve to create a curve-driven tangent draft, but if you want to control the draft angle, create the curve as a parting line with the appropriate angle, as shown in this example.
1. Click Mold > Draft Line. Accept the default name for the draft line. The menu manager opens and the DRAFT LINE menu appears with the Parting Surf check box selected.
2. Click Done.
3. Select the parting surface.
 
* The parting surface must belong to the reference part.
4. On the DRAFT LINE menu, click Parting Crv. The CURVE dialog box opens.
5. Enter 15 for the draft angle (the draft angle of the parting curve defines the future draft angle of the tangent draft).
6. Select both halves of the rounded surface (1) of the reference part, as shown in the following illustration.
7. Click Okay to accept the direction of feature creation.
8. In the CURVE dialog box, click OK. Then click Done on the DRAFT LINE menu. The system creates the parting curve, shown in orange in the next illustration.
9. On the Mold tab, click Draft > Tangent Draft. The Tangent Draft dialog box opens. Accept the default Pull Direction and the Geometry and Direction defaults on the Results tabbed page.
10. Click the References tab and select the draft line. On the CHAIN menu, click Curve Chain, select the parting line created in Step 8, then click Select All and Done.
11. Click . The tangent draft cut is created as shown in the following illustration.
