I have updated to Designer 2017 on PC. In files created in 2016, the 3D representation of the plants do not appear in the model when updated to 2017. Plant objects work fine in files started as 2017 files. This has been reviewed by Tech Support and their recommendation is to not bring my 2016 models into 2017. Is anyone else experiencing this? Many of my jobs span multiple years and going back and forth between multiple versions of vectorworks is a pain in the dark side. I'm hoping that they are working on this for the next Service Pack, but am unsure. I have seen different threads that say don't bring older models into newer drawings, but I don't plan to keep every version of VW on my computer just so I can work with old files. I did wait until service pack 2 before upgrading in hopes of minimizing bugs. Any thoughts?
