I mocked up what I personally think would help organize the mess that is the tool library when you're working on parts with multiple setups.
The majority of my parts use multiple setups, and some setups get bounced between different machines. So tool #s are usually numbered as a per setup basis so any guy in the shop can grab it and load the tools needed numerically.
The problem now is when looking at the tool library with multiple setups, all the tools are just mixed together, making it a mess to sort through. in the image below, I've renamed each operation to help show how messy and unorganized the library view is.
My proposal is to add another drop down under the document file you're working on in the libraries panel on the left. So in this example, "Tool Library Setup Examples". See Image below...
Now when you click on the design file you're working on in the library panel, each setup will have it's tools grouped together. MUCH easier to figure out what goes where. If you're using the same tool in different setups, that shouldn't be a problem, just list it under both setups. Taking it one step further, if we could then click on the setup name in the left column, it would then only show tools for that setup, as seen below...
I was going to submit it to Request a Feature, but figured I'd get some feedback first. What do you think? Make sense?
