The feature I have been looking for is variables & file names used to make part numbers.
So specifically: Document number = Test string +Assembly name + Part name + Revision level
Then if the Assembly gets renamed, so do all the parts.
Some parts it would be really nice to use: Document number = Text string + a cut length
This can already be done with an exported variable used to create flat pattern names. That feature is called document name formula. But Document name formula is not available to display in draft or used to drive part names and or numbers.
I wand a feature like document name formula to drive part numbers from any mixture of variables.
Just a bit of better veriable flow would go a long way to help numbering parts and keep track of model files.
but the advantage of the new BiDM is, that there is no further need for looking at the filename.
You can use all properties for searching etc. without knowing the real filename.
You also will show properties in the pathfinder (that's what the Document Formula really is) rather than the filename.
So my advise for the future would be: "Don't care about filenames, use Properties!"
It's not something I need, it's something I want.
I want to drive part numbers of multiple assembly driven parts from the assembly name.
that way when I copy & rename the assembly (and it's draft and parts), I also get new part names without any work.
So yes I would use properites, driven by the file name.
Custom properties you make up as you go.
I use two of them: Shape and L
L = cut lengh of anything, created by adding a PMI exposed as "L" or renaming the extrusion lenth to L
Then L is formatted to show up in the parts list
I use Shape to hold descriptions of shpe used within the frame tool. Example: Angle 2" x 2" X 1/4" CS
I have both Gage or Shape show up as my second column in the part lists after item number.
