I am attempting to draw a swept or extruded shape while rotating it at the same time in Mastercam X8. To be specific, imagine a square with 4 holes in it in a square bolt hole pattern symmetric to the center of the square. I would like to extrude/revolve the square to make a solid but I would also like to continuously rotate the square about its center by a total of 90 degrees as it is extruded or swept in its path. This will result in the holes moving in a uniformly changing helical path. The edges of the square will also twist so that, for example, the bottom edge rotates 90 degrees to become the right edge, etc. I understand that this would be very hard or impossible to machine as described but I actually plan to first make an STL so I can 3D print it then machine the final result in very short segments for machining purposes and put them together later. Is this possible in Mastercam X8? I can not figure it out if it is. Can anyone tell me how to do it or if I am just wasting my time using Mastercam to do this? Thank you for your help.
