How to space holes at specific intervals around a cylinder

[drewpaul]

I have the body of the part, but I am not able to figure out how to space the holes correctly. Here is what I have:

Revolved to produce:

What I need is to position three 1/4" holes spaced 120° apart around the cylinder, and .8" above the base of the cylinder.

This is the view of the opposite side.

I need the center hole to be positioned along the axis, ie opposite of the notch.

Any help will be greatly appreciated!!!

Welcome to the forum.

Looking at the sketch I assume the part is hollow? If yes, use a simple Extruded Cut for the first hole. Start the sketch on a plane at the center of the part and parallel to the notch (create a new one there if there isn't already one there), then choose "Through All" for the end condition. Use the circular pattern for the other two (set to three instances evenly spaced).

I believe you can place the first hole opposite the notch where desired (using a 3D sketch) and then do a circular pattern for the other two.

I'm glad I could help, and I like simple. Many of the people here who have known me for years (at least through this and other similar forums, if not in person) will probably be happy to tell you that I am simple.
