B-Spline and Plane Intersection

You can create a point at the intersection of a B-Spline and a plane. 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.

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

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

  2. Select the B-Splines you wish to consider.

  3. Select one or more planes 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.
