Thanks for all the suggestions, Benson! I have tried to go through all your suggestions, but I'm still not able to correct it
the point cloud geometry is still present on the v2022 design layer
not showing after making all classes visible, both in the viewport and the sheet layer.
the cloud is not outside the viewport area either. See the screenshot below. When hovering over the viewport, the edge of the point cloud is shown with dashed lines both before and after the viewport is updated. I can even see the preview-snapping of points in the cloud when resting the cursor. But the points themselves is not visible... arghh
Clip cube settings? I'm relatively new to vectorworks, as you might suspect but as far i can see the settings are OK. I can go to the design layer and see the clip cube perfectly fine. From any angle.
I think this has to do with the clip cube combined with the viewport in some way. The point cloud disappears when the viewport is updated int the OIP. The point cloud displays nice in a viewport where the clip cube is not used. And like @Tom W. suggests, the size of the points are affected by the sheet layer DPI setting. I have tried to play around with the other settings for the viewport as well, but with no result. ...
