Place mesh from surveyors data - slow performance

[Anonymous]

Hello!

I'm wondering why Archicad file and the performance becomes so slow, when importing point clouds and creating the terrain (Place mesh from surveyors data). When I open this in other GIS programs for example, it works very fast.

I don't have much experience, but I believe this terrain made out of these points include more information, then I actually need ...
Is there any way to increase Archicad performance, maybe if I simplify the terrain or transform it in any different form?

Any advice will be appreciated

I use Archicad 22.
Thank you.

Huge point clouds do not work very well or not well at all, at least on my computer.
