I have got to say, this is a very sad thing.
I have spent the last 20 hours looking for ways to create a database from scratch. When I couldn't find information on how to do that, I looked at ways for just updating the database and adding individual pieces of material. This information is pretty scarce also.

Some of the methods I found for just adding a part to an existing database were very convoluted, hard to understand and so far, really haven't worked for me.

My last avenue is to actually make every single piece of a manufacturers line by hand in CadMep just to be able to use brand specific and model specific parts.

I find it utterly impossible to understand how there isn't any information out there on the workflow for creating a database from scratch and a decent guide/tutorial on adding specific parts to an existing database using manufacturers .rfa files.

Again, if anyone can lend a hand, it would be much appreciated!
