I can't subtract solids?

[Bruce Kieffer]

This seems to be confined to one file. I cannot subtract solids for some of the objects in the file. I'm trying to understand why. In fact, all of the solid operation commands are grayed out. I have different layers and different classes. I thought maybe that was the reason so I assigned the same layer and same class to the offending objects and tried to subtract. Nope, still grayed out. But if I move all of the objects to a new document, then I can subtract solids. The classes transfer, but the layers don't. I don't know if that means it's something to do with the layers.

AFAIK

Solid Subtract/Add only worked when both share the same Layer.

I ran into it a lot at the beginning of my VW career.

 

But if you already tried to use the same Layer in your initial file,

either it was not the Active Layer and/or Layer(/Class?) edibility Settings

or it is something else.

I have it working now. Not only do both or all objects need to be on the same layer, that layer needs to be active too. I rarely use layers, so this is new to me. I hope I remember!
