Function Description

The Trim tool trims the intersection of a selected line object (baseline) and another selected line object (trim object) that intersects it.

• Trims the object to the cutting edge defined by the baseline object. When using the Trim tool, select the line feature (baseline) to trim, and then click the intersecting segment to trim. The part where the mouse clicked is removed, that is, trimmed off.
• Applies to objects with trim line layers or line objects with CAD layers. The Layer of Object to be trimmed is also required to be editable.
• Trim works only on line objects that intersect the baseline, and nothing happens on line objects that do not intersect.
• The object to be trimmed must be a simple line object; the baseline can be a complex line object or a simple line object, but cannot be a Compound.
• To continuously trim multiple line features that intersect the same line (baseline), select a line object as the baseline, and then continuously trim the line objects that intersect the baseline.
