Circular Pattern of a Feature

kermit_achterman

I have a basic solid cylinder with one axial hole which is not on the cylinder center line. I am unable to create a circular pattern on the hole about the cylinder center line.  The box is asking for a part or a face to pattern but will not accept a hole feature.

We currently don't have feature pattern.  In this case, I would try to use a face pattern and select all of the faces of the hole.

Meaning that you need to select the cylinder AND the bottom (if the hole is not going through).

As face pattern is not very robust solution against future edits to the part I would suggest using sketch pattern instead and extrude all sketch entities with one extrude command.

Bear in mind that if you want to adjust the number of holes with a variable, you currently must use the face pattern option as sketch patterns won't accept a variable (I've been told this will be fixed).

Is this recommendation only because there is only a face pattern and not a feature pattern?  I only ask, because most of the time in Solidworks, I see it typically recommended to NOT use sketch patterns and instead use feature patterns.  Just curious because I'll use both, depending on the situation.

If there was robust feature pattern I would use that. My suggestion is just my experience with Onshape.

The problem is that if you edit something in history that affects to faces in the pattern it will break.

For holes face pattern is decent solution if run by variables. With more complex shapes that might need update later on it is not good in any case.

I hope we would see feature pattern/mirror in next updates.
