The Inventor team has posted some interesting content on our services and support site, covering how to:
- Publish a drawing from Autodesk Inventor to DWF format
- Add review markup to the DWF file
- Load that markup in the Inventor drawing, and then review the markup
It is being referred to as a "Skill Builder" and intended to assist those who are creating markup callouts and comments in Autodesk Design Review as well as those who are assessing and responding to those markups within Inventor.
