I've read several questions and answers and none seem to apply to me. I want to make a wall with a cutout for a door. Using Blender 2.8, here are my steps:
- Create a new 'general' file
- The starting cube will be my wall. Since I live in a backward country, I don't do meters. Instead, I'll type units as inches. So I scale the cube to 4.5 m in the X direction (the wall is 4.5 inches thick), 120 meters-as-inches in Z direction, and oh, let's say 240 inches in Y so that it's 10 feet tall and 20 feet wide.
- I move the Z location of the wall to 120 so that a Z of zero is the floor
- Great! I have a wall!
- Make a door with Shift-A, add Mesh->Cube
- Scale it to 6, 30, 80 to make a door 30 inches wide, 80 inches tall, and thick enough to use as a boolean difference object. Set the z-location to 80 to bring it up to the floor
- I select the first cube and Add Modifier. Select Boolean, difference, and the doorway object
- Click Apply
- Select the doorway differencing object, hit G and X to move in the X direction to move it out of the way to see the hole in the wall, and...
- There is no hole in the wall. Why?
I'm 100% certain that this is user error. I just don't know what error I'm making. Can anyone show me my mistake?
