Trim or extend

Trim/extend changes the length of a line or an arc. You can use Trim/extend to lengthen or shorten lines and arcs as follows:

1. Select Construct tab > Geometry panel > Edit > Trim/Extend to enter trim/extend mode.
2. Click an endpoint of a line or an arc.
3. Click the new point. You can also drag the mouse to locate the new endpoint location.
Note: The new point does not have to be exactly on the line or arc. This does not change an element's orientation (location, angle, or radius).
4. When you have finished trimming or extending lines and arcs, exit trim/extend mode.
