Help making neat holes in a plane?

I’m trying to make several clean holes through this plane here, but I cannot get looptools to make me a proper circle…


Then this happens:

I just need clean holes in the mesh, but looptools keeps giving me oval cuts, and I can’t scale it to fix anything either, just gets worse…

You might have scale your object in object mode. To fix it, go to object mode, select your object and press ‘Ctrl + A’ then select “Scale”. This will set the scale of your object to 1 on all axis (does not affect the actual appearance of your object)

Thanks, I got it. Solved!
