B-Spline and Surface Intersection

You can create a point at the intersection of a B-Spline and a surface. The command follows the B-Spline from its tail toward its head and creates a point when the spline first pierces the surface, only creating a single point. You can select multiple surfaces with this command, but still only one intersection point will be created.

To Create a Point at the Intersection of a B-Spline and Surfaces:

  1. From the menu, select Construct>New Points> Intersection>B-Spline and Surface Intersection.

  2. Select the B-Spline.

  3. Select one or more surfaces to test.

  4. When prompted, enter an approximation tolerance. Generally, the default value is fine.

  5. The Construct New Point dialog will appear. Leave the coordinates as-is (they are calculated for you), and specify the desired collection, group, and point name (or select an existing collection or group from the dropdown.

  6. Click OK to create the point.
