I would LOVE to see Drag'n'Drop functionality from Vault to Inventor Assemblies and the Application Window, While keeping folder references valid.
At the moment you can Drag'n'Drop files from Vault to Inventor, but it opens them from a temporary directory. Now that Vault allows us to specify a default Project File. it should be able to open the part from the working directory instead.
Ideally it would allow us to drop a file into an assembly by dropping into the assembly file edit window or open a file by dropping onto the application title bar.
This functionality would enable users to search Vault for parts using keyword search (skip the 3rd party PLM system in our case), browse the search results using thumbnails, then just place the desired part straight into our assembly without the need to 'Get' the files, then 'Place' them.
Awesome idea... Make sure you spell my name right in the credits!
