> Also, how would you describe such things as "attributes". good point, will have to think about it. (autocad attdef command, to make it clear) door size, window text description, and so on. It should fit into the whole system. If a block is a directory, then each directory could have some "attributes" defined by something that externally "calls" that directory... This means, that even the 'root' drawing can have "attributes" ;) -- # Janek Kozicki
