# 2.2.17.4 Trim a Draw Object using another Draw object

The Trim Draw command can be used to trim many draw objects (Straight Lines, Curved Lines, Circles, Polygons, PolyLines). Polygons and Circles are split into PolyLines and Curves.

1. First a Trimming object (draw object) is selected with Left-Click. Until the trim draw object is selected, a draw object under the cursor will be highlit in blue. Once it is selected it will be highlit in the current Select Color.
2. Next the point of intersection between the trim object and an object to be trimmed is selected. Until a split point is selected, a suitable split point under the cursor will have a blue trim anchor that is a T shape aligned with the trimming object.

The trim anchor base has an arm that indicates which side of the trimmed object will be deleted. A Left-Click will trim the object.

If the trimmed object is a circle or a polygon, the result will be the same as a Split (Section 2.2.17.3), a 355 degree circle and an open polyline with ends at the split will result.

Once a trim has occured, the trimming object remains selected for another trim.

To leave the command use the spacebar. If Sticky (Section 2.10.8) is set for Split commands you will be able to select another trim object.
