Trim Two Lines
Shortcut Key: Ctrl+E
Trims (or extends) two lines at their intersection, forming a clean corner with no overlap. This command trims lines, curves, and arc entities.
Point 1: First line to be trimmed
Point 2: Second line to be trimmed
Click Trim Shorter End if you want to trim the shortest ends of each line. Otherwise, the part of the line that you click is kept, and the other part is removed.
The lines will be trimmed at their intersection. If the lines do not intersect, they will be extended to the point of intersection.
Trim Picked Segments Only: On polylines this forces DesignCAD to trim or extend only the line segments that were clicked. Otherwise Design- CAD will trim or extend the polylines at their closest intersection .
NOTE: If you are in 2D Mode, you can trim two lines that don’t intersect by trimming their projections on the XY plane.
