Rotating features in a circular pattern

BTWaid

I am trying to rotate features about a line in a circular pattern but it is not working.  When I choose the line for the axis to rotate the features, the description for the line is changed to "edge of sketch" and the rotation does not work.  What defines an axis and can I create one for rotation?

Thank you!!!!

Hi @mitchell_machelski. Welcome to Onshape. Check out the Forum Post Checklist. Specifically, try posting a link to your document. Otherwise, trying to explain your question just looks like a lot of verbal hand-waving that probably won't get many answers if any. But if you post a link, I and many others on the forum will jump through hoops to fix your problem. We're handy like that

Here's link. The slot on the outer diameter is what I am trying to rotate on a circular pattern.  I've done it before with success.

@mitchell_machelski link is not working.  Check that it is correct and public

I forgot to make it public.

Can you leave the failing circular pattern in your document?  I'm looking at your document and your sketch line should be fine as an axis, but I'm not sure what you are trying to rotate, and what you mean by failing.  Does it create unexpected geometry or is the feature actually red?

BTWaid

Okay I did...

Link still isn't working, though. Likely only OS employees can see.

The link is public but it's sort of messed up up there ^.  You'll notice it says http twice.  This should work:

@mitchell_machelski I would try a face pattern instead of a feature pattern. Feature patterns are tricky. They're great in theory, but there are some important downsides. First, since you're patterning the features, you have to also pattern any reference geometry that would be required by the patterned features (planes, etc). Feature patterns also take longer to rebuild. If you have a complicated set of features that need to be replicated exactly (like on a flat even surface) with no modification, face pattern would be a better option. Alternatively, if your feature is the result of a Boolean, then try a part pattern followed by a Boolean on all the patterned bodies.

@mitchell_machelski

As stated in the error message (accessed by hovering your mouse over the feature name), you need to select "apply per instance":

Ah, and then there's "apply per instance". I forgot OS just added that option this week This in effect makes your feature pattern a face pattern, but without the inconvenience of selecting individual faces.

Thank you!!!!

@mahir

Just to clear things up:

Having "apply by instance" off something similar to a face pattern using feature selections.

Having "apply by instance" on does the old behavior of feature pattern (re-executes the features in the selection for every pattern instance).

@Jake_Rosenfeld, gotcha. I forgot a "not" somewhere in there
