two coplanar faces found

I was trying to do a boolean operation on two objects in Blender, but it wouldn't let me. It said "blender cannot execute boolean operation: two coplanar faces found." What does that mean and how can I fix it?

This error message means that the two objects you're trying to boolean are coplanar, meaning they lie in the same plane. In order for a boolean operation to work, the two objects must be non-coplanar.

There are a few ways to fix this. One is to simply rotate one of the objects so that it's no longer coplanar with the other. Another is to use the "Split" tool in Blender to split one of the objects into two pieces, then boolean the two pieces separately.

Whichever method you choose, the important thing is to make sure that the two objects you're boolean-ing are not coplanar. Otherwise, the boolean operation will not work.

Q: Why is Boolean not working in Blender?

A: There could be several reasons why Boolean isn't working in Blender. The most likely cause is that the objects you're trying to use Boolean on are not properly aligned, or that the topology of the objects is too complex. Another possibility is that you're using an older version of Blender that doesn't support Boolean operations.

Q: How do I enable Boolean modifier in Blender?

A: In the Properties panel (N key), go to the Modifiers tab. Click on the Add Modifier drop-down menu and select Boolean. In the Operation drop-down menu, select the desired Boolean operation.

Q: How do you use booleans in Blender?

A: There are a few ways to use booleans in Blender. One way is to use the Boolean Modifier. With this modifier you can add, subtract, and intersect meshes.

Another way to use booleans is with the Bool Tool. This is a separate tool that can be found in the Tool Shelf (T). With this tool you can add, subtract, and intersect meshes as well.

One last way to use booleans is with the Sculpt Mode. In Sculpt Mode you can use the Dyntopo boolean tools to add, subtract, and intersect meshes.

Q: How do you make a Boolean permanent in Blender?

A: There is no way to make a Boolean permanent in Blender.
