For each individual project, I have a folder name which starts like SD005. The assemblies and parts I save in this folder is manually saved with assembly numbers as SD005AS001 or parts numbers as SD005PA001, and so on. Is there a Macro which can be used when we create a new part or assembly, and when saved, SolidWorks automatically assigns the next file name (which is same as part number)? The automatic file name should have a prefix of SD005 based on the folder name. Currently I am inputting a name manually, for which I have to check which is the latest part number available, which is time consuming. Any advice please?
