You already have Fusion linked to McMaster-Carr to be able to search and download models of say fasteners directly into your "assembly". All part numbers are right there. However, when placing an order on McMaster-Carr's site, I would have to go back in and individually place those parts into the cart. This could take some time. I think you should add a feature which would automatically place all McMaster-Carr parts you have in your current "assembly" into their cart ready to purchase and complete an order. This would be a huge time saver as well as make sure you're only ordering what you need and not forgetting anything. If it's in your assembly, it gets ordered. I have such complex assemblies at times and can have serval hundred fasteners/parts etc.
Anyway, that's my idea.
