I'm trying to use BoolTool and the Boolean modifier with no success. I want to cut out the cylinder from the widget in the attached file.
I did look at The Boolean modifier is not working and checked for inverted normals, duplicate vertices, and non-manifold geometry using the 3D Print plugin.
(I switched the names of the two objects in the file. Oops!)
Please let me know what I'm doing wrong. I keep running into these problems. I'm using Blender 3.2.0. Thanks!
