Rhino newbie... just learning the ins and outs...but have been working in 3d software since before time began ( i.e. before the web was created, in the days of FTP sites and DOS CAD. Started out on the Amiga 2000...and have been pushing every machine and software since to try to do things I want them to do...always end up using 1/2 doz. programs to do what I need done, and that is always a complicated answer to what seems to me to be a simple procedure!
