SPLINE

Purpose:

To highlight all spline node tangents in a user-indicated (spline) contour (for example, created by the Insert Spline function) and optionally insert them as lines in the current drawing.

Instructions:

1. In the Insert menu, click Tangents, then Spline.

2. The user is prompted to indicate the (spline) contour to verify. Once indicated, all spline node tangents in the contour are highlighted and the user is prompted to confirm the insertion.

   If confirmed by user, all spline node tangents are finally added as lines in the current drawing.

Options:

None.

Result:

All spline node tangents in a user-indicated (spline) contour are highlighted and optionally inserted as lines in the current drawing. Note that lines inserted at a previous stage will not be duplicated.
