Creating a detailed 3D FE model of a slope in PLAXIS 3D


Dear GeoWorld community

I want to create a 3D Finite Element model in PLAXIS3D based on a fairly detailed UAV mapping of a slope. To reduce the size of the file, the point cloud has already been sub-sampled to a 1m spacing (~20,000 points). Is there an efficient way to import the point cloud into PLAXIS3D and subsequently create a numerically stable 3D FE model?

Best Regards,

Hi Sally

Interesting question.

You can import the UAV map via the point cloud functionality in PLAXIS 3D. See e.g. this video (second half):

If this does not work, please reach out via https://apps.bentley.com/srmanager/ProductSupport where our Technical Experts are ready to help you out.
