How are attachments added to masterdata in Model Manager?
Select the Masterdata item in the structure, then click on Add New. There are different options for what type of items you want to add.
I use Add New > Document > MISC_DOC to store DXF and STEP files for the part.
Hope this helps!
Masterdata cannot hold any type of files/attachments directly.Masterdata can only be linked to any type of Document (Drawings, Models, general documents etc.)This is what Mike describes.
