Because I cannot get the add in directly for Autodesk I am going to pay someone else for nearly the exact same thing. You mention that Autodesk does this to entice the end user to maintain a subscription but in my case it has done the exact opposite.
I have become very proficient with inventor and never used the maintenance package after the first 60 days so why keep paying for it? All im getting at is that it would be nice to have access to the add ins without paying for a bunch of other stuff that isnt needed.
I dont feel I need to pay for a product that I have had no use for. Some apparent reason? Sarcasm isnt necessary, friend.
