Creating double-sided draft surfaces

1. Choose Surfaces > Draft surfaces > Draft/flange ❐
2. In the option window set Construction Type to Draft.
3. Under the Advanced tab, turn on Double Sided.

   A Single Surface option appears.

   

4. Select one or more curves.
5. Click the Go button in the lower right corner of the window.

   Draft surfaces are built on both sides of the curve.

   The Angle, Surface Depth and Pull Direction apply to both draft surfaces.

   

6. Turn on the Single Surface option, to build only one surface, extending on both sides of the curve.

   

7. Use the dotted green line handle on the manipulator (under the white triangle) to toggle Double Sided on and off.

   

Handling corners

1. Choose Surfaces > Draft surfaces > Draft/flange ❐
2. In the option window set Construction Type to Draft.
3. Select two adjacent curves.
4. Click the Go button in the lower right corner of the window.
5. Change the angle (from the option window or using the manipulator) so that the drafts move away from the surface and do not intersect anymore.

   

   The draft surfaces are automatically extended, intersected and trimmed to form a sharp corner.

   When the angle is such that the drafts move toward the surface, they are simply intersected and trimmed, as before.

   NoteBecause the depth you specify for the Draft is preserved, the top edge of both surfaces may not meet exactly at the corner.
