1.4.5 - Trim Objects

When an object intersects with another object, you can remove its unwanted portion by using the Trim tool. To trim an object, you need to first invoke the Trim tool, and then select the cutting edge (intersecting object) and the portion to be removed.
If there are multiple intersection points in a drawing, you can simply select the 'select all' option from the command line; all the objects in the drawing objects will act as ‘cutting edges’

Begin the Trim command via Toolbar icon.

• On Ribbon ► Click Home tab►Modify panel ►click Trim icon (Fig.1.4.5.1) .
