Thank you Hans,
I had a look and see your point.

I made a few changes to the gallery and tried to "copy as new furniture" again but still cannot paste into "restaurant". [>:)]

This should be straight forward enough but I just cannot see what I am doing wrong.

I have SH3d 2.6 (?) on a friends windows computer and will play with that later.

I have uploaded the changed designs to the same link as before.
If you want to have a look. I really appreciate your help and efforts [:)] [:)]

Best Greetings
Fred
