yep, in case anyone else trying to do the same.... I created the individual houses in a separate "clean" drawing.... exported them as OBJ as advised above, then re-imported them as a piece of furniture into my main site plan.

thanks for the helpful tips

... or would itbe easier to draw the individual house in a seperate , clean drawing, then export it, then introduce it the main drawing as a piece of furniture.... that way I guess I could select all in the separate drawing
maybe I;; try that

thanks a lot for that
I cant see how to select just a part of a drawing, across all levels...when I select all, or all levels, it picks up everything, how do I pick up just one part (as in 1 house) across all its component levels ... apologies if my question is asking the obvious or a is a bit ...

Has anyone found a solution to this question... I am currently using SH3D to do a quick and simple site master plan for a 50acre site in which I have 3 different multi-story house types.... which I want to copy and paste around the site and with different angles.
My problem is the same one as above ...

I found a page with links here that worked for me
https://sourceforge.net/p/sweethome3d/d-models/330/

thanks tho

Hi, I wonder if one of you could please re post a SH3d file with 4-side pitch roof, or a library of roof... the links above are no longer active.
many thanks indeed

great, thanks so much for that...didnt know about the double click, thats exactly what I needed.
cheers

Can anyone suggest how I can set a room level to a higher or lower level than the default, so that I can have split levels
for example, the default is about 2.4m... but I want to have a room with a roof or ceiling height of say 4 or 5m, in between floor levels of 2.4, 4.8m etc
I have figured out ...
