Trimming Objects in AutoCAD

You can cut an object precisely at an edge defined by one or more objects. Objects you define as the boundary edges or cutting edges do not have to intersect the object being trimmed; you can trim back to an implied intersection. Cutting edges can be lines, arcs, circles, polylines, ellipses, splines, xlines, rays, and viewports in paper space. Wide polylines are cut along their centerline.

In the following example, you join two walls smoothly by trimming the section where they intersect.


To trim walls where they intersect

  1. From the Modify menu, choose Trim.
  2. Select the cutting edges with a crossing selection (1 and 2) and press ENTER.
  3. Select the section of the wall you want trimmed (3) and press ENTER.

Command line TRIM
