To Trim Linework or Profile-Based Objects to an Edge

Use this procedure to trim one or more lines, polylines, arcs, circles, hatches, AEC polygons, mass element extrusions, or spaces precisely to a selected edge or side of any straight segment of AEC linework. This feature lets you easily trim linework to components of walls.

Tip: If you need to trim linework to the edge of an arced segment of an object, use either the Crop option or the Subtract option. The Crop option removes linework outside the implied boundary of the arc, while the Subtract option removes linework inside the implied boundary of the arc.

  5. Click when the trim line displays.
  6. Click the side of the trim line you want trimmed.

    All selected linework is trimmed to the edge you selected.
