Solid Modeling OD Holes on a Diameter for Mill Turn Projects - Lathe 2020

[mayu]

Hello eM,

Looking for some bright ideas on how to create holes on to the OD of a solid cylinder. This is essentially a 6-hole bolt circle pattern on the OD of a part.

As shown below, one of the holes is on center at the 'Front' plane.

At first glance, the logical approach was to create this hole, and then copy the rest of them around the OD with 60 degree spacing.

But it's not working - not sure what's being overlooked.

How can I create this bolt circle on the OD of the solid?

This is for Lathe 2020.

Thank you

UPDATE

FYI in this case we are lucky because the holes are symmetrical and thru to the ID of the part. That means we can create planes on half of the holes, and then make thru holes with the 'Solids > Hole' feature.

But this approach seems over-engineered, and would be cumbersome for example if the part had 20 holes on the OD.

Once you have created a single circle wireframe you can rotate that around the OD like you have done. then in "solids" you need to select the "extrude"  feature. Then select all of your circles making sure the chaining direction remains the same for all of them. Once you have finished selecting the geometry change "create body"  to "cut body" and you can set a distance with which to cut the shape. This will create all of the holes from OD to ID. This is just 1 way of getting this task done, there are other options as well but I usually use this method.

Make one hole and then use Solid circular pattern with the Right View as C-plane. Type the number more you want and the angle and done. One at 180 degree for 2 holes or 359 at 1 degree for 360 holes your choice.

Yeah that was the trick - being in the 'Right C Plane'.

This is a clean approach, especially when there are alot of holes and you do not want to manually select each one.

Thank you for your time.
