Data Cards are used to store the meta data for all of the different documents that go into EPDM. You can have a different data card for SolidWorks, Word, Excel, etc. so each will store different variables and have its own look.
Folder Cards are the same, but are for the folders only. Folder data can be easily passed down to sub-folders and document data cards so you enter info once and share it downstream.
Template cards are where you input folder and/or data card info upon creation of the folder and documents. You can set mandatory fields, serial numbers and other up front data entry formatting here.
Very basic primer. Have specific questions...ask away.
Perfect answer...had the same problem last week teaching my scouts lashings. Been doing it so long I don't know whether it's square, diagnonal, shear...I just do it and move on. It's when I have to take that moment and explain why, that I sometimes get extremely flummoxed. Thanks
