Pull a surface from a set of curves
 
 
 

Use Draft to create a surface in the form of a set of profile curves along a pull angle.

Set up the Draft tool

  1. Choose Surfaces > Draft Surfaces > Draft/Flange .
  2. Set the Mode to Draft, then click Go.
    TipDrag the tool to the shelf to save a custom version of the tool in Draft mode.

Pull a surface from a set of curves

  1. Choose Surfaces > Draft Surfaces > Draft/Flange in Draft mode.
  2. Click the curves, then click Go.
  3. Do any of the following:
    • Use the pull direction and angle/depth manipulators to adjust the draft surface.
    • -click a point on one of the original curves to add another angle/depth manipulator. (Input curves must be at least tangent continuous for this to work).
    • -click an angle/depth manipulator to delete it.

    NoteAt corners (where the original curves share endpoints), the Draft tool will extend the draft surfaces to fill any gap if necessary, then intersect and trim them, to form a sharp corner.

Set the pull direction

Interactively, with the manipulator

Through the Vector Options in the option box

Set the angle and depth at a point along the draft surface

What if...?

The surface has problems, and shows red dotted lines?

The pull direction is too close to the tangent of the curve indicated by the red dotted line.
