I made a tool to speed up the process of creating trim detail in Maya. I uploaded it to Gumroad a while back and figured I would tell people here about it. If you happen to try it I'd be happy to hear what you think, if it's helpful to you or not. This was originally made for some old co-workers who were wanting an easier way to create these types of Trim in Maya.
In a nutshell, the way it works is you create a profile curve, select some continuous edges, and hit a button to extrude a trim piece along those edges and it also creates uvs for you.

Thanks for reading!
Update 2021: the quick install script may not work on Maya 2020 and later. if that is the case you should still be able to source the script and shelf button manually.
