Place mesh from surveyors data detail level

Hello, I am trying to create a mesh from a point cloud that I've simplified in another project to have points with a spacing of 0.1 m, but when I import into ArchiCAD using the "Place mesh from surveyors data" it seems that ArchiCAD does a simplifcation as well, and I can't manage to get a more detailed mesh than with 1 m between points, especially in the z-direction. The result is thus a choppy mesh with "shelves" not at all the level of detail I would like and have in my point cloud.

If I put the surveyors unit to say millimeter the same simplification takes place, but now the distance between points are 1 mm (and the model scaled accordingly).

Any ideas on this?
This is the ArchiCAD mesh, with exactly 1 meter between points.
This is the original point cloud, with 0.1 m between points.
