One of the things that ADN team does together with various product teams is API wishlist survey. This year's wishlist survey is now open for Revit and Navisworks from the following links:
Please take a moment to complete these surveys and give us a feedback. It will take less than 5 minutes to complete each survey. Our engineering teams use this feedback to help prioritize the areas of API enhancements in coming releases. If you leave your e-mail address, we will send you the final results after it is concluded.
The deadline for the survey for Revit and Navisworks API is June 1st, 2012. We look forward to receiving your feedback!
