Extend (Curve) 
Access: Open this function from one of the following locations:
-
Select Wireframe > Main Tools > Extend from the menu bar.
-
Select Curves > Extend from the following Die Design Guides: Strip Design.
Extend a curve. The existing curve is either modified or a new curve is created.
The existing curve(s) are extended linearlylinearly or naturallynaturally. Among other advantages, the new, separate curve allows you to measure the angle between two curves at the point in which they intersect.
All kinds of curves can be extended such as line, arc, 2D spline, 3D spline, helix, trimmed curves, offset curves, projected curves, as well as face edges. Composite curves and closed periodic curves (circles, ellipses) cannot be extended.

Examples of the Same Curve and New Curve options:
|
The curves below have been created using the Same Curve option that ensures that the curve and its extension are one entity. |
The curves below have been created using the New Curve option that ensures that the orange and green entities remain separate. |
