Actually they didn't make that distinction but I think they should! I used that image in a slide for a Autodesk University session in 2006. It comes from the Rev'IT! site, a Dutch motocycle clothing and accessory company that has the distinction of owning Revit.com originally (and selling it to the Revit we know).
CTC's tool set has the nice price of $0.00 listed on their site.
Included for this nice price is:
- Delete Backup Files
- Type Catalog Tools
- Compare Shared Parameters
- Merge Shared Parameters
- Family File Version Detector
I'll leave it to their site to explain the tools and their purpose but I think anyone whose made more than a couple families will recognize some value just from their description?
