its hard to understand how to use this plugin, unlike in autocad just click or type the fillet or chamfer for 3d objects and type the radius, but this plugin has so many options.
UPDATE : don’t bother of this post, i know now how to use this Plugin.
Glad you figured it Kage. If other people come across this post and need some help with this tool, take a look at this SketchUpdate post about Round Corner or this post on SketchUCation.
thanks sir. I know this will help others.
