CONTOUR

Purpose:

To highlight all node tangents in a user-indicated contour and optionally insert them as lines in the current drawing.

Instructions:

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

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

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

Options:

None.

Result:

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