Projecting Points to B-Spline

You can project points directly to any arbitrary B-Spline or curve. The projected points can lie directly on the curves or can be backed off the curve by a specified amount. Each point will be projected to the closest curve among all candidates.

To Project Points to a Curve:

  1. From the menu, select Construct>New Points>Project Points to B-Spline

  2. At the prompt, select the curves to project to.

  3. Select the points to project.

  4. The Point Naming dialog will appear. Enter or select the desired group to contain the projected points. In the Add Prefix or Add Suffix field, enter a prefix or suffix that you’d like to attach to the point names, then click OK.

  5. At the Probe Offset dialog, enter a distance to offset the projected points back away from the curve. This value must be positive, and always shifts away from the curve.
