To Convert a COS by Intersect
Use this procedure to convert a COS by intersect to a COS defined by points. The COS will lie on one of the sets of surfaces you selected when you created the COS by intersect. To convert other curve types, use the To Convert Curves procedure.
1. In the Model Tree, right-click the Style feature that contains the COS by intersect to convert, and choose Edit Definition. The Style tab opens.
2. Select one or more COS by intersect to convert.
3. Click Style > Curve > Convert. The first set of surfaces that you selected when you created the COS by intersect is highlighted. You are asked for confirmation.
4. To convert the COS by intersect to a COS defined by points on the first set of surfaces, click Yes. To highlight the second set of surfaces, click No. You are asked for confirmation.
5. To convert the COS by intersect to a COS defined by points on the second set of surfaces, click Yes. To cancel the conversion, click No.
