Hello @JA, I'm currently testing the app Building Structure to create modular houses for North American residential houses. As well the app is oriented for steel structure buildings but many functionalities are interesting for homes too.
First I wonder if there is a way to create my own catalog for structural members? I've a couple of standards sizes of lumber that I should reuse across Building Structure app.
FYI @MH, @MK, @KC @VG 
Thank's
