Safe to Delete all Materials?

[sdcartmell]

Just checking.... are there any out-of-the-box Materials that definitely SHOULD NOT be deleted from a project or project template? I'm planning to update our template materials' names, attributes, etc and noticed there are two sets of Phase materials... Searched around for any opinions about it online and couldn't really find anything. And that's just one example, there are a bunch of questionable default materials floating around in there. Thoughts? Free to Purge x3 or hold onto everything like it's a sacred gift from Autodesk?

Thanks!

All? You really what to delete the “Default”, “Phase” and “Analytical” ones?  But, sure you can if you want. You can always reload them into your Project from the default AEC Materials ADSKLIB.

Yes.

I'm very much interested in clearing out anything that isn't necessary. What's your opinion about deleting "Phase-Demo" and keeping "Phase - Demo"? They're both included in the default Imperial Architectural template. "Phase - Demo" is in use as a phase material in the phase graphic overrides, while "Phase-Demo" is not in use, i.e. it shows up in the Purge list. Is this duplication of the Phase materials just a mistake? Or is there some deeper purpose?

Thanks for the tip about the ADSKLIB!
