Why is my circular pattern not defined?

I am new to Onshape, so please pardon me if this is a dumb question. I am trying to create a 2D circular pattern about the origin in a sketch. I am starting with a black defined element. When I set all the parameters and click on the left mouse button the pattern appears as expected, but all of the elements in the pattern are blue (undefined) except for the original element. I thought that I must have done something wrong, but then I watched the tutorial video and the same thing happens in the tutorial video. How do get the elements in my pattern to be black (defined)???

Re: Why is my circular pattern not defined?

You need to make the center of the pattern coincident to something (seems like you want the origin in this case). If you drag the pattern slightly you should see a blue point which is the center of the circular pattern. Add a coincident relation with the origin.

Re: Tangent Mate is bistable (and I don't need it to be)

I also fully agree. A tangent mate in a 3D model (maybe other than in a sketch) could refer to surface normals in order to make a tangent mate stable by default. That is what I would expect.

Re: Perforate a cylindrical shape

Hey Mark. Here is a method you might be able to use to perforate your part. Playing around with the shape (shapes?) in sketch 1 might get what you want. The Circular Pattern feature allows the removal of pattern instances should the pattern fall upon an edge of the part, which I assume would be undesirable.

Beyond using Onshape's native tools. Evan Reese created a custom feature you might be able to use. Check out this post for a discussion, link to the feature script and a video of using the feature script. - Scotty
