Why has my green part some unwanted holes?

Dear community,

I am newbie in OnShape (used FreeCad for years) and I am wondering why I have these holes in the green part, even if there are no holes drawn in Sketch5 - and also Sketch5 is drawn on "Face of thicken 1" where also no holes were introduced yet.

Thanks a lot in advance!

Holes that are on the sketch face are imprinted by default, causing them to appear in your extrude. You can open your sketch and disable imprinting if you don't want to reference the face you are sketching on.

Micheal's idea is a good one but a 2nd approach would be to simply select the two circular areas along with the rectangle that you are extruding (three picks instead of one) if for some reason you don't want to disable imprinting. Having said that, my preference is to run with it turned off.

Looking at your feature tree and the model, I would recommend going through the free training which is available. Normally to create shapes like this, you would use Extrude, not Thicken. Training would also help with the imprinting issue.

I was sure it would be easy   
Good to know. Thank you Michael for this quick and helpful response!

uh, you are right, I thought I tried this already. But thank you Rick, it works too. Good to know! 👍
