Shortcut Key: E

Toolbox Icon:

Trim (or extends) a line to its intersection with another line. This command also works with curves and arcs.

Point 1: Line to be trimmed

Point 2: Line to trim against

Click Trim Shorter End if you want to trim the shortest end of the line. Otherwise, the part of the line that you click is kept, and the other part is removed.

The first line is cut off at its intersection with the second. If the first line does not intersect the second, it is extended until they meet.

Trim Picked Segments Only: On polylines this forces DesignCAD to trim or extend only the line segment that was clicked. Otherwise DesignCAD will trim or extend the polyline at its closest intersection with the trimming line.

NOTE: If you are in 2D Mode, you can trim two lines that don’t intersect by trimming their projections on the XY plane.
