Hi, im new to rhino, i am using the mac version if that makes any difference, so far ive managed to create what i want to a fairly accurate degree, and 3d printed it with great success. now progressing my idea forward i will do my best to explain, i have a wheel or ring shape if you like, and on the inner rings edge, i want to create a geometric assortment of triangles that eat away at the edge, so they look pushed in almost, i want them to look seeminly random in size and position, but i want them to be all the way around the inner rim, and all connected. my best example of this effect would be,
this look, but imagine it around an edge of a circular hole. i know how to extrude a shape up, but if i wanted to draw a shape and push into the edge, how can i do this?
i hope that makes sense, if not please let me know.
Edit. I do have access to the windows version is well, in my university.
