Another point of view... I work with complex polylines and would like to use the offset feature to help define geometry for 'cutter diameter compensation'.
My work around is to offset the polyline. Then I go thru the polygon to manually insert arcs using 3 point snap points. Then I delete all the short lines. This keeps my file size down to a reasonable level... which helps recalculation & redraw times. A gillion little lines also bog down subsequent 3d modelling.
Please, please make the offset tool insert arcs. It would save alot of time.
Thanks
