Scan2BIM modeling from a point cloud

[sophie_schleiermacher]

Hello,
I recently carried out a Scan2BIM process and created a model of a building with Revit based on a point cloud. The version is 2024.1. I had big problems with loading the point cloud, it has a size of about 2GB and the computer has very good performance. The point cloud is only loaded extremely slowly or sometimes not at all, the individual steps (e.g. placing a wall) take forever.
I tried to solve the problem by giving Revit more access to the RAM, but that didn't help either.
When I saved the project and wanted to close it, I had to close Revit via the Task Manager because the program could not shut down on its own and at some point the computer hung up.
What could be the reason for this? Is it due to the point cloud link?
Many thanks for your help!

It a  is a large Point Cloud file and the level of information could be causing the issue.  I would suggest trying the suggestions in the following link.

A rule for working with computer specs for data models is;

1. CPU

2. RAM

3. MEMORY

3. GPU

I have worked with point clouds in excess of 35Gigs with no problems.  Probably 32Gigs of Ram min. Also, point cloud needs to be loaded from local C drive (no spinning disk) or over a server. This will take forever.

Having the point cloud on a local (and fast) SSD drive definitely helps. I've also heard from a lot of people who split or thin out their point clouds, e.g. using ReCap. Additionally, there are several plugins available that address Revit's limitations regarding point cloud size and visual quality, which might be worth exploring depending on your specific needs.
