Do you mean adding new or missing parts to build with in LDCad? The program will search for parts in any of the locations listed under Prefs->LDraw->Search (library) paths. You can add new parts to any folder you like, and then add that folder to this list (if it's not already there) as an "unofficial library". Just be sure it has the necessary subfolders of p\ and parts\ and that any required subparts are placed in parts\s\.
