I’ve tried repeating and I’m not seeing anything to suggest other than Persistent on Mesh not working with the 3DFace. This is in both Single face and Multiple Face modes of 3DFace. Seems fine in 6.27.20147.8371, 26/05/2020, example is in 7.0.20147.12475, 26/05/2020. OnMesh tooltip disappears after the first pick.
Whilst on the topic, maybe it would be good to extend persistent options to SubDs too, for ‘draw on’ options as well. (take a vote on whether a SubD is a surface (extract surface) or a mesh…) - actually, I see it works as a polysurface already which is cool.
Also, Cursor Tooltip > Command Prompt disappear after orbiting the camera. Maybe that’s by design. But the command prompt tooltip remains after orbiting if it has another tooltip alongside, such as ‘point’.
