I am working on an apartment building project. The layouts of the individual apartments are referenced to a hotlink module. The file is getting to be too big so we want to break the file into modules (west wing, east wing, etc). However, when I select everything in the west wing and say "save selection as module", the smaller modules don't seem to transfer to the new module file. Is there a way to save a group of existing modules into another module file without losing their information? Thanks
