Export issue model and point cloud position

Hi Team,

I’m experiencing a strange issue when exporting both a 3D model and a point cloud of the same object. They should share the same coordinate system, but after export the 3D model is perfectly aligned, while the point cloud appears shifted in Z as well as in XY. The export settings are identical and export from the same reality scan 2.0.1 project. I’ve attached some images to better show the problem.

Thank you

I can try to help. Can you provide the asset IDs for the exported model?

sure

the 3dmodel is 3859178 coordinate system epsg 3004

the point cloud is 3860951 coordinate system epsg 3004

both are exported from Reality Scan 2.0.1 with the same parameters

hello to everyone, any news?

A small update: I tried another object, exported directly from Revit using the plugin with coordinates in EPSG:32632. The point cloud is also in the same coordinate system. However, I found out that most export tools don’t actually write the coordinate system information into the file header. So I injected the EPSG code into the LAZ file using PDAL.

Even though this reduced the misalignment, it didn’t eliminate it completely — there’s still a noticeable offset. In Revit, the point cloud and the BIM model are in the same position, with a maximum difference of about 3 cm, much smaller than what appears in the Cesium scene.
