Make a hole in a face created by the solidify modifier

Question

I have half a cube that has a solidify modifier. I want to make a hole in 1 of the faces created by the modifier, but it doesn't work with boolean.

How can I make a hole in a solidified face?

hello, it should work, please share your file: pasteall.org/blend — moonboots, Commented Aug 5, 2021 at 14:10
what do you mean with "half a cube"? can u provide screenshots? — Chris, Commented Aug 5, 2021 at 14:24
you can use built-in adon called Bool Tool, and than select both objects and press ctrl+Numpad- — CheatPekalongan, Commented Aug 5, 2021 at 14:50
cheatPKL, That works very well, but what are the lines that I see afterwards and how do I get them away — MIck, Commented Aug 5, 2021 at 15:16
Those lines are the bounding box of the boolean object. If you hide the boolean object in the outliner they will disappear. — John Eason, Commented Aug 5, 2021 at 15:28

It should work. Here's a cube that I cut in half and applied a solidify modifier to:

Here's a cylinder positioned to cut the top and bottom faces generated by solidify

Here's what it looks like with the cylinder hidden and a Boolean added to the cube:

Here's the modifier stack for the half cube:

Some things you need to be aware of

The solidify has to come before the Boolean on the modifier stack
You have to use a cylinder to cut the hole, not a circle; but a smaller cylinder would cut just one face
You won't see the modifier in edit mode, unless you enable the Edit mode visibility
The cylinder won't disappear. You either have to hide it, as I did, or set it's Viewport visibility appropriately to something like wire or bounds.

Thanks, that works, it was that I had the boolean after the solidify. — MIck, Commented Aug 5, 2021 at 15:21
