You can still provide you input in feet, just follow all values with the foot mark ', like 10'. Resurfacing a solid (for planar surfaces): Note: Sometimes I’ll decide to extend a solid or surface, and the subcurves of the original surface still show, which is annoying if I decide to alter it another way afterward, like extrude it in the other direction or fillet it. In SketchUp I can draw a rectangle on the face of a flat surface and extrude that rectangle out of the surface or into the surface. The surface can therefore not be exploded. Rhino. And have bunch if such iterations. A common operation in any Rhino for Mac workflow is joining multiple curves into a polycurve, or breaking a polycurve into its component parts. not working under the assumption that the entire part should be made in Rhino and then transferred over, but rather built from both and assembled in SW.
