Can't create a circle

[[Cl...]]

CAD - Creating Features - Creation. I change to wireframe, click on the
wire circle and when I try to create the circle, I get this error message.

FYI, the ACIS Interface window is open?

Can you create a curve and then recall feature points into a circle?

[[Cl...]]

Yes, that works. I'd rather use the circle.

[[Ri...]]

I've seen this before, but I wasn't able to narrow it down. I wonder if it has something to do with your defaults?

[[Cl...]]

Don't think so. This is an intermittent problem.

[[Me...]]

Try selecting multiple creation instead of the circle.

[[Cl...]]

Nope, keep getting the error.

[[Ow...]]

You might try auto-healing the model and if that doesn't work, try creating a different line by sectioning the model in the area.

[[Cl...]]

I healed the model (again). Then I sectioned the model, clicked on the new circle and I still get the error.

[[Ow...]]

You might try rebooting everything while slamming the mouse on the desk 5 or 6 times and cussing, lot's of cussing.Seriously, it's worked before. 🤣

[[No...]]

Some models are picky when it comes to the selection of certain features. I think it depends on how the specific area was created and what type of edge was created in the process. Even CAD programs sometimes refuse to perform certain operations unless you change the way in which you create a feature. Recently I tried to add a simple edge radius to a model consisting of several boolean-united cuboids. --> Not possible. Only after uniting them in a different order, it worked. One would that shouldn't matter, but it did. Healing probably won't cure that kind of issue.

This is just one of those Calypso mysteries. What happens if you open a new program use that same model and then try it?

I've had weird errors where whatever is wrong is fixed and Calypso refuses to go back to working right on that program.
