You can contact any Autodesk product team personally with a web form. This web form goes to the management for the products including QA, product managers, and software development. This is not product support so please do not submit a request to teach you a product or solve all your questions daily. You can use this to report an occasional issue, problem, or to make suggestions on what you like or do not like in the products.
- Go to Autodesk.com
- Select "Contact Us"
- Select "Feedback", "Products"
- Select the product you want to provide feedback on.
- Be nice and detailed, it is real humans that receive the feedback. :-)
- Complete the form and submit.
On submitting the form it is sent to many on the Management and many are directly responded to, at least on the few teams I participate on.
