I’ve sketched the half section for a knob, drew a circle perpendicular to the section’s axis, selected the circle, selected the followme tool, and selected the half section. But it left blank areas.
I’ve done this before with no problems, but this leaves me without any ideas. So I’d appreciate any suggestions that you can offer.
Opening your model now but I’ll guess it’s because you are working at too small a size and running into the tiny face issue… Use the Dave Method for this. Make a component of the profile and circular path, copy the component, scale the copy up (I generally use 1000x) open the component and run Follow Me. Close the component and delete it. Return to the original where you left it.
