Trim to Intersection

Used to extend and/or shorten two elements of any element type to their intersection.

When an element is extended, the end nearest the point where it was selected is moved, and the other end remains unchanged. When an element is shortened, the part of the element that is selected is kept.

You can access this tool from the following:

Ribbon: Drawing > Home > Modify
Ribbon: Modeling > Home > Modify
Ribbon: Modeling > Curves > Modify
Toolbox: Modify

If you turn off the Identify Elements Automatically check box in the AccuSnap Settings dialog General tab, you get a preview of the result of the tool operation and you can accept or reject the operation.

Key-in: TRIM TOINTERSECTION

Note: No modification is made if the selected elements cannot be extended so that they intersect.

Note: To extend two multi-lines to their common intersection, use one of the "construct joint" Multi-line tools.
