Thanks Emilio, I like both ways, yours and Skyg. Yours would be better where offsetSrf sees a surface go not quite where one wants it to, as can happen , e.g if a deformed metal sheet then has a hole drilled, offsetSrf would have that hole with non parallel sides if hole created before the command…or if a cylinder has splayed end and a planar end area, offsetSrf puts the second surface beyond or within planar depending on direction chosen.
Thanks Skyg, I find myself doing metal bending from time to time and wonder if Rhino was best for this, especially having asked beforehand what prog was best for me when indicating such needs, I also find Rhino intuitive and the forum is second to none on help, if anyone asks me what prog to get the forum is a key component.
I bought TurboCAD at a special reduced price with support via phone/email a while ago so that I could try it for the bends, and Rhino for everything Rhino is best at. I hit a hurdle immediately when TurboCAD wouldnt show the lettered points of an imported Rhino file, answer was to select the points then alter lettering properties, but without being able to find them …how ! I replied with this dilemma and never got an answer. Whole process took a week, so not a good start.
Also the 4 window viewport of Rhino wasnt there and that was really unsettling as to how to view the object, guess I shall need to have a good stab at it with a day to get into it, not in a hurry as I was.
TurboCAD for Rhino users would be a good guide, if I could find one, showing the differences. I hope commands have same names, thats a start, nothing worse than different names in progs for same command.
