I have a model like this:

Base model

I addet a plane, resized it, and created circles at two corners using SHIFT+A. Now, I want to remove the faces from the circles from the face of the rectangle. Also I want to delete these two circles later. How can I do this? Please note that I'm a Blender beginner :)

Thanks for your advice!

You can join all the shapes if it's not already the case (select the objects and CtrlJ to join), select the circle and CtrlF > Intersect (Boolean) and in the Operator box (at the bottom left of the 3D view once you've booleaned) choose Boolean Operation > Union and Solver > Exact :

enter image description here

Then you can remove the circle. Or, as John Eason suggests, use the Knife Project tool.

  • $\begingroup$ I am using Blender 2.79 because of DirectX compatability; when I click Intersect (Boolean) it creates some weird looking shapes and if I delete the circle, it deletes the rectangle too. imgur.com/a/nK3yXTi $\endgroup$ Jun 12, 2022 at 15:00
  • $\begingroup$ In that case, look for a tutorial on the Boolean Modifier for your Blender version. On reflection, you could also use the Knife Project tool assuming it was available in those days. $\endgroup$

  • $\begingroup$ I trust you that this is working in Blender 3 so I will accept that :) $\endgroup$ Jun 12, 2022 at 15:13
  • $\begingroup$ Yes Kinfe Project works in 2.79, the shortcuts are not the same as in 3 though, see this tuto: youtube.com/watch?v=J0lA9iJxnlM $\endgroup$
