Wall by face not working properly

[dimitris.katsarelis]

Hello all,

I've created a mass and I want to use a face of it to place walls.

As you see in the screenshot below, the walls do not follow the mass face.

I have a few workarounds to do it but I'd like to have it as clean as possible, especially avoiding any MIP sweep voids.

Any ideas why is this happening?

So, that is the result of creating walls via Massing tab=>Wall by Face?  Strange.  What about not using a Mass and instead, using Attach Top/Base tool to attach the wall top and base to reference elements?  Not "clean" enough?
