Change All Family Parameters to Instance Based

Use this script in the Family Editor to change all family parameters from type based to instance based. Type parameters with formulas that reference other type based parameters are not converted. To resolve, remove the formulas and then run the script again. The recommended steps is to run this once first, then check tosee what didn’t convert.

A real world scenario is mainly for plumbing. In order to have Pipe Accessories and Pipe Fittings attach to pipes and automatically take on the size of the pipe, the nominal diameter/radius parameters must be instance based, and all other parameters referencing these parameters also need to be instance. Thus it makes sense to have all the parameters instance based. Will get into detail in another post.
