Hi Tom, I guess it may just not come up as often in MoI as in SketchUp because usually you're working with curves in MOI while SketchUp works on polygons and polylines.

Is there a particular kind of project where it's helpful to have this?

In SketchUp does it only do this on a single line, not a whole polyline?

Maybe I could incorporate this better into MOI as an option in the Trim command.
