Have you noticed how parameter groups (i.e. Dimensions, Identity Data, Graphics) display in a different order in your projects from how they are listed in the family editor? If you want to make it easy for users to access the most important information in your families, you’ll want to know the project sort-order.
I tried putting the controls for my window muntins in the Visibility group, but it was a big pain always having to scroll down or close the Identity Data group that would get in the way. I tried putting the parameters in the General group instead, thinking that it would display in alphabetical order, but it still came in under Identity Data.
So if you want to make informed choices about which groups to use, without a lot of trial and error, check out this list put together by Gordon Price – it’s super helpful!
