I've never found a way of getting additional sub-folders in the material database. I would organise it so instead of having a single Stainless Steel folder, I would have separate folders for each major group; "Stainless Steels, SA-240", "Stainless Steels, SA-249" etc. and maybe a catch-all "Stainless Steels, Others".
Alternatively, would just sorting them alphanumerically help with searching through them?
Thanks Dave, How can I organize it as you described? I am not sure how to seperate the folders as you are saying.
Fire up a part, right click on the material in the Feature Manager Tree and hit Edit Material.
Right click on Enerquip Materials and select New Category. This will be what you want to rename to something like "Stainless Steels, SA-240."
Go to your original Stainless Steels category, and right click on the material you want to move and select Copy.
Head back down to your new category, right click on it and select Paste. You can then right click and Delete the material from the original category.
You can then use the right click > Move Up / Move Down to re-order the materials alphanumerically within the category. The categories themselves can also be right clicked > Move Up / Move Down to re-order within the library itself.
Hope that helps!
Thanks Dave!, I will give it a shot today. If I have any other questions I will let you know.
I really appreciate the help!
