Imagine a cylinder, but cut in half so that the cross section of
the object looks like a half-moon. I am trying to bore holes (fastener
holes, couterbores, etc) into the curved surface of the half-cylinder, but
(of course) perpendicular to its flat plane.
I have tried 2D sketch on the flat plane, an offset 2D sketch
(both above the curved surface and intersecting it), and a 3D sketch, but
I cannot get the holes to bore into the surface using the Hole Wizard. I
either get an error or the holes bore from the other (flat) side, which is
not the side I want.
What is the easiest way to get what I want? Any help? Thanks very
Well, the problem with this is that I have no idea what fastener
holes I need yet; the design constraints could change. It's also easier to
see how different holes and hole features behave if you use the Smart
Dimension after putting the hole in with your design. I have to put holes
in around edges, so I have to make sure there is enough material to keep
I'm sure there is a way to do what I proposed, but I don't know
the proper way. Thanks,
Nice demo, though I wouldn't use so much reference geometry.
If the holes won't be intersecting the axis of the cylinder, it will
probably be necessary to cut-extrude some flats into the curved face before
adding the HW holes. Depending on the holes and the size of the flats, some
sort of clean-up features may be necessary.
That's exactly what I want, except I need the counterbores to be
perpendicular to the flat face of the object (and off-center). But I can
generalize from what you have already shown.
