Thanks for the link I will check It out but my question is will it take the mutable segments of a circle and /or a arch and mesh or weld or whatever them into a closed loop when exported to other cad programs.
no.. those links were aimed more at imaginearch's post..
sketchup is going to export segmented circles just like they are when they're in sketchup itself..
or, are you saying the segmented circles are ok.. it's just that when you bring them in to another program, they aren't staying joined together as a closed loop?
