Advice - Large drone scan mesh into Archicad

[Aazmatazz]

Hi guys,

Im looking for a bit of advice.  
We have survey drone data from a site, which has been supplied to us as a 2023 sketchup file.  
Archicad throws up errors when trying to open (AC can only open skp files from 2019 and beyond).  
I opened the file in sketch up and it runs fine.  I saved the file out as an earlier skp file, imported that into AC and it worked!

The problem is the mesh is just over 1 million polys, so it grinds AC to a halt.  The mesh seems to work absolutely fine in both Sketchup and Blender though so im wondering if I've missed a setting or im approaching the import wrong?

Any advice would be much appreciated as im pulling out my hair on this one.

Hi Mike 96,

Please take a closer look at CloudCompare. The output can be point files (xyz, txt etc.) as well, not only Point Clouds.

The goal is to reduce the number of points in a way that Archicad and your hardware can handle it. AC needs point files with only 3 columns (x,y,z) in it and no additional point data. With this AC can create a mesh which you can work on.

I agree that a mesh with a million points makes AC slow down....but do you need this density to get some buildings placed?
