Have just been playing with files and have created a couple of floors as separate files. Now I want to try adding stairs between the two floors, turns out this wasn't the smartest idea. Anyone know if I can merge 2 files. Have altered one file so that z = 3.7 m and have left the other one at z = 0.

Thanks

Copy/Paste should do what you need.  To merge stuff from Model A into Model B:

1. Open Model A
2. Select the stuff you want to merge
3. On the Edit menu, click Copy
4. Open Model B
5. On the Edit menu, click Paste

Unfortunately there is no copy option on my edit menu. ctrl c also does not work.

I'm sorry, I was thinking of PyroSim.  You're right, there's no way.

I'll add that to the list.

Thanks.
