Board n batt the Rene way. Can't do it.

Mr Rabbet's vid shows making a material region then making it an architectural block.  I select the object (the region I made on a west wall) and see no way to make it a block.

 

What's wrong?

I get the arch block button as soon as I select two or more material regions or custom backsplashes.  If you want to make the block out of just one, you need to hold down the shift when you select it.  This puts you into group select mode which makes the block tool show up.

 

If it's not that, then you probably need to post the plan.

I use the backsplash feature to create mine.  This way when it breaches the doors and windows it's automatically cut.  Create one on in elevation on the floor you want it on then array it across horizontally.
