Not sure why but those settings works for mass, etc. only. If you need to control decimal places for other things, use equations.

Go to end of this post and check how to use equation for controlling decimal places Display Mass in Dual Units in SolidWorks

Sorry but it looks these are broken with the changes made to VBA or equation managers.

Sarah Dwight:

**Is there a complete list somewhere of functions that work in the equation manager?**ROUND is a Excel/VBA function and equation manager can handle some of those but not all. Not sure which all it can handle.

Go to options, then Document Properties, then units. If you change the length decimals to however many you'd like, that will sort it.
