I am new to blender and am having trouble inserting "inward beveling" the walls of my mesh. I am using 2.91 of Blender.
I have the walls defined - below:
I am using cylinders as templates to create the arc I want in the primary cube. I want to now "cut out" the cylinders and create new walls aligned to the edge of the cylinders where they intersect and bevel inward on the primary cube. Then I need to add some thickness to those walls.
Here are images from the top of the primary cube and bottom so you can see the vertex.
I have tried the boolean modifier but it does not create the inner wall - it just removes from the faces that the cylinder intersects with on the primary cube. And I am having some issue there where it's not delete anything from the top face (the one without the extrusion). It might be I need to add a grid fill to create more faces.
Any help is appreciated.
