In SW can more than one user work on an assembly file and a part file at the same time?.
Yes, but the last one to save wins! The FILE/RELOAD command is very handy as is having the options OPEN REFERENCED DOCS READONLY and DON'T PROMPT TO SAVE READ ONLY DOCUMENTS. You check the first so as not to lock everyone out of documents you are not intending to change and you check the second to prevent overwriting others work and keep you out of SAVEAS hell. The discipline part is that you have to remember to uncheck READONLY in the RELOAD command and then reload the document before changing anything in the document. And of course you have to remember not to change a document that is read only.
