Import Point Cloud to a Shell Model

[TGS4]

I have a point cloud from some laser scanning that I want to use to generate a shell-element model in Abaqus/Standard. Does anyone know of any good third-party software or any good python scripts in Abaqus that will accomplish this import?

My data consists of ~2million tuples of x,y,z point data.

How are the points gonna join together and make the shell elements? It would be very helpful if you put a small part of the file and describe the relation between the points.

As a first pass, I would say that the laser scan data is in a regular grid pattern. The shell elements would likely be generated using the data points as corner points. There's no way to upload a "small" portion - it's a massive file.

As an update, I have written my own python script, which modified an existing mesh based on the point cloud. I generated a model of the un-deformed item. Then this python script calculated the deformed location of each node, based on interpolating from the poitn cloud.

Hi TGS4!

I am also working on scans.

Was wondering, is your resulting part an orphan mesh or a geometric part?

Thanks in advance!

Neither, it's a modified mesh.
