Missing 3d lines on Cameras
« on: January 12, 2022, 06:47:42 PM »

I have a project where I created DEM. I added 3d lines describing borders of parcels (plot). The point is to update the altitudes and to show borders on pitched cameras, taken along the building site.

However, for no reason some of the lines disappear and appear on neighbouring cameras. First I though, that it was due to "hiding under dem", but as I can see it is not a rule.

How to cope with it so that all the lines appear on cameras? What is the reason for them to disappear?

Looking forward to getting any clue :)

Hello Damian,

Can you please check, that all the "disappeared" shapes have all their vertices above existing DEM surface, if they disappear after using Update Altitudes feature.

Maybe you can also share a project copy (to with the camera alignment, drawn shapes and DEM surface, so that we could try to reproduce the problem and investigate it?
