Got a doubt in trim tool in AutoCAD. What is the option “Projection” inside the trim tool about? Need clarity please.
It has effect, when you are trimming something within 3D space but not in 2D.
Trim -> Project has three options: None, Ucs and View.
When Project is set to None, trimming lines have to cross each other in the space. Otherwise they will be not trimmed.
When Project is set to Ucs, lines will be trimmed by their projection to XY plane.
When Project is set to View, lines will be trimmed by their projection to current view.
