Lightweight vs Read Only

Read-only would signify that you don't have the rights to change it, while someone else could. It still loads the complete part set into memory. Lightweight loads the part without loading all the info into memory, only adding info as needed.

Read only mean you can't save the file over it self, only to a new name or not at all.

Lightweight only loads enough information into memory to display, calculate distances and mates of that part. You can't edit the features of that part from the assembly level, you would need to open that part itself to change any feature.

So if I have some parts open 'Lightweight', I actually have 'Write Access' to them. And if somebody wants to open the file, they would only be able to have 'Read Access', correct?

Yes, you can change a lightweight part to "set to resolve" then edit the part. Also you can then change it back to lightweight and the change will be saved when prompted to do so or you save the part.

Yes, others would only have read access unless you changed your access to read only via the reload command (SW2K5).
