I want to do a circular pattern (x4) of the "leg" of the part in the file I uploaded. Specifically the one named "19". I'm supposed to fit the finished part on file "1". I managed to do a circular pattern on file 1 but I can't seem to do it on "19". I don't know why.
When doing your circular pattern, be sure to select bodies to pattern and this should solve your problem.
You also need to choose what to pattern around (your curved surface/cylinder) you can choose an axis or like I did just the circular edge, not the surface.
