When I do a pack and go from Solidworks Explorer - the date of drawing files (and models with drawing) is change to the current date and time (i.e. when the pack and go is done). This happens even if I'm not using update prefix or suffix. However, models with no drawings are not change. Does anyone know why it works this way?
Brian, Do you know why the model (parts) with drawings also update their date and time, but why model (parts) without drawings do not? ~Ed
So the drawing file changes due to the path change of the part file. Does the part file keep track of each of its "children" thus updates as well?
I don't think a typical part will have any external references (unless it is designed in the context of an assembly - top down design, or inserted parts within a part file.) Don't think I can explain the date and time change you are seeing.
Ed,
I think you found the answer. If you open up a part that has a drawing, you can right click on the part at the top of the feature manager tree and select "Open Drawing". I suspect that has a link to the drawing file, and thus the part changes when the drawing file changes.

The internal pointer to the external reference in the Drawing file is literally inside the file, and includes the full path to the model, therefore something inside the drawing is updated, and the drawing file is not an identical copy.
