Height difference of an exported 3D-model (3Dface dxf)
« on: March 06, 2021, 12:53:29 PM »
Hi everyone,

my exported 3Dface dxf files seem to have a height difference to the real world of about 2.5 metres. The project is geo referenced with GCPs and I don't know what is wrong.
The export coordinatesystem is EPSG 31467, Gauß-Krüger 3

Can you help?

Thanks in advance.
Best regards
Sebastian

Hello Sebastian,

Do you observe similar height difference, if you use ruler tool in Model view to get the coordinates of some point, for which the altitude information is known?

Hello Alexey,

no, if I look at an GCP with the ruler tool, the height is nearly the same (about 1cm difference, but I didn't click exactly on that point).

Sebastian
