I love to have the opportunity to create my own parts, which has been implemented with the introduction of the Infrastructure Parts Editor (thank you), but it requires Inventor! Inventor is not even part of the AEC collection. It would be much easier (and cheaper) to be able to create the parts with one of the software that come with the AEC collection, like Autocad or Revit. I love to learn new software, but honestly I don't think it's very convenient to learn and buy Inventor just to create some parts for IW! Please change this, Inventor is NOT the right tool for this. Thank you.
