Cant Creat Wall by face

[Anonymous]

Hi guys.

I am trying to create wall by faces of a Mass I modelled.

This is the Mass: http://prntscr.com/xz4iv

Everytime I try to create a wall by face of one exactly face, it accept Location Line: By Finish Face Interior only, when I try to change ANY other Location Line, it gives me a message error.

And it is always from the SAME FACE highlighted at the picture.

Does anyone knows how to fix this?

The mass was made by the floors and top edges. I select all of the edges and create a mass from down to top.

All the other faces are ok and they accept the wall by face and let them change the Location Line except this one.

Try editing the Mass, and mirroring the "one that works" over from the left side.

Then create Wall by Face. Any luck?
