Drawing Walls on a Different Layer

[WendyWelton]

Michael,

Anything shown only with cad will not show in 3D. That's why I use the method it sounds like you were originally persuing - Removals as cad, Existing To Remain as walls (with or without segregation from New by layer and/or wall type).

To elaborate on the cad method: You don't have to edit to remove the ETR. Simply assign the whole wad as Back group and a lineweight that's less than your other stuff and it will sit there quietly minding it's own business, showing only where there's really a removal. As a bonus, it's there as a guide. If you accidentally move something that's supposed to be ETR, you will notice it, because your ETR cad will show where it should not.

Michael, as I said, this is a personal preference. Even if you place walls on a different layer, they are still walls in the plan. That is something to think about. Even in a different layerset with the existing walls changed in appearance and on a different layer, just by turning them off in a layerset doesn't mean that they're not in the plan anymore. Way too many things can possibly happen with room def. for one and other things depending on what you're doing. A complicated or extensive remodel could possibly turn into a nightmare.
