I work on 10 projects, each with its own shared parameter file. Every time i open a different project i have to change the file path. Why? Revit should remembered different path on different projects.
You're going to get in trouble if you use multiple Shared Parameter files.
You really only want to have one file for everything.
The Shared Parameter file contains a unique GUID for each parameter in it.
If you have a parameter by the same name in two different SP files, they WILL have a different GUID and you can end up with duplicates in your project.
Also, which file do you use for Tags?
A Tag created from a project based off one SP file will not work on a project based on a different SP file. The parameter may have the same name, but it won't work.
We tried one file for multiple projects ... doesn't work as expected. Is like wishing a template for every projects. Impossible. We have always to adapt to reality, not the opposite. And worst..
1. Projets has it own parameters type/naming and convention. With time, it become quickly a real mess. 2. Too many parameters are alike or unlikely duplicate. 3. Projects might upgrade Revit version, for different purposes, once or twice during the whole process.
That's only few examples...
We started each project with a duplicate from the "master" shared parameters. So far, it works better and it is more manageable, unless your work on multiples projects.
