Hi, I am currently building some dynamic components, "pcmoor", for building construction. I too have been frustrated, however I believe the problem is in editing independent of the main model. For example before reusing a previous component to build the next, copy within a main model, then make all parts unique, use the outliner to select all the sub components at once, then make unique. thus any changes will not effect similar components. Then if you want too place into another file. One day someone needs to write a book....interested? cheers Philip

Thank you, Dale! I´ll look up this information about the Idea Center... as far as I´ve researched, i can create a library of objetcs there (which I was also trying to find out how to do... ) but I haven´t managed to import any SU files yet. I´m aware that on version 10 the quality of that import is perfect, but when I find out about that import on V9 I´ll update this post! Thank you so much for the help!
