AutoCAD Inventor :: Parameters Units And Decimals

Inventor 2010

- I have drawing partslists with parameters that change automaticly
- Based on a main assembly with a customized structured BOM, with information I fetch from the individual parts exported parameters (Ex. =Length <part-length>)
- The main assembly is based on many sub-assemblys
- Based on "Make Component" skeletonmodels
- Based on embedded EXCEL worksheets in where I control my parameter values.

Now the problem expl.:

- Total I have about maybe 50 parts, witch have 15 parameters each, that I need to control this way.
- In every single part I have derived it's parameters from the skeleton part, and exported them.
- On some parameters I don't want to show the units, in most of the parameters I don't want the trial zeros.

So in the individual parts parameter table I choose "Custom Property Format" for the exported parametern in every individual part.

-uncheck "Trailing Zeros" and check  "Apply to existing...", then uncheck "Unit String" for some parameters.

I lot of setup work with 50 parts, 15 parameters each (750 individual parameters).Every time I change a dimension in the embedded EXCEL worksheet, ex. a pipe dimension and thickness, a diameter for a revolved feature and so on, the units go back to it's default values again and I have to do all this parameter setup "Custom Property Format" again.
