Hi Lorenzo,
Thanks for your feedback. These are all items on our list, but as they are coming later I can’t commit to a deadline when these will be available. We will continue to invest in Drawing throughout the year, so if there is anything else missing for you don’t hesitate to share it with us.
However, you can already achieve adding coloured 3D views to Drawings by creating a capture in the Visualisation space using the transparent background and then adding the captured image to Drawings with image import. Let me know how this works out for you
