I don't know if this idea has already passed through this forum but I believe a key feature that Flow design is missing is the possibility to render the model. A lot of the work I have done in Flow design usually needs to be continually documented and displayed near the end of any projects so I always use Flow Designs current image capture setting. The issue is that is just doesn't look professional. I realize that by adding an in-app renderer the download time would be massively increased so I believe there should instead be an option to export the model with the CFD data to render in another piece of software such as Autodesk Showcase.
