Kinda good PC, kinda bad performance (pointcloud)

Karol Argasinski — Sun, 31 Jan 2021 09:39:22 GMT

Dear all, especially dearest GRAPHISOFT staff,

I am writing with an issue, which I can't resolve:
I am running ARCHICAD 24 with newest updates. My workstation specs are:

AMD Ryzen 7 3800X
Nvidia Geforce RTX 2070
32GB RAM DDR4
Drives: SSDs and NVMe
Windows 10 Pro with newest updates

and unfortunately, archicad project, when working in 3D (pointcloud attached) is really slow. I am working with pointclouds for many years and I was filtering them always (the pointcloud attached is like just 1GB).
I reinstalled drivers for graphic card, it didn't help.
Maybe there is some kind of solution for that? I can send files to check.

Best,
Karol

Hi Karol,

Thank you very much for your question and I am very sorry for the experience!

From my experience, the Point Cloud module in Archicad is not very well-optimized. In some cases, you may experience some slowness when navigating in 3D. Nevertheless, it is not very clear to me what is the main factor for the slowness. A 1GB point cloud file can be as slow as a 3GB point cloud file. Nevertheless, I haven't encountered a point cloud that makes the file to slow to be usable (but of course it also depends on how complex your project is when importing the point cloud in).

When you have performance issue with point cloud, is it an empty project or is it a big project already?

Looking forward to hearing from you!

Best regards,
Minh

As you know very well I am sure, there is no need to import a pointclouds into ArchiCAD with PointCAB. And there is more and more software available all the time that automatically generates vectors, mesh, surfaces, etc... which is what we are really trying to get from a pointcloud.

So what are some reasons that you might want to import a pointclould into ArchiCAD if you are already using PointCAB software?

Hi Steve,

You're totally right . We know PointCab and we love it. The thing is, sometimes, it is crucial to check stuff in 3D and even show something to the client in a "3D world" .

I love Octree Filtering in PointCab and I am working on pointclouds on ARCHICAD since the module made it debut in v19. Still, file "that big" shouldn't make so much fuss to my PC. That's all I am concerned.

Best,
Karol

Hi Minh,

Thank you for reaching out.

I think there might be hardware issue, since it wasn't a problem on an old drivers. Also, maybe newest Windows 10 Update? Did you have any signals on that kind of matter?

Please send me PM, so I can contact you further on that topic.

Best,
Karol
