I have an issue I am not able to solve! I have made an object of various components in one file and want to copy this into another file, but only parts of it follows! I always do it this way, for instance making a bar, I have a cupboard in one file and need to copy it over to the building itself, and this is always problem free. But now it doesn't work. I have made the components as 3Dsolids. Anyone know what to do? The same components also disappear when I zoom in or out and sometimes when I orbit too.
