Problem when i try to run "Convert Point cloud to revit element mesh" with large point cloud file

I have a problem when i try to run the below example but with large point cloud file

Convert Point cloud to revit element mesh by using python 3 and Open3d

Point_Cloud_To_Mesh.dyn (57.5 KB) Hi I need to share with you how to convert point cloud to mesh by using use python 3 and “Open 3d” Package in dynamo 1- load Open 3d packedge in to your dynamo 2- voxel_down_sampl downpcd=pcd.voxel_down_sample(voxel_size=0.05) 3- used dbscan to cluster point cloud and remove the noise point labels1 = np.array(downpcd.cluster_dbscan(eps=0.05, min_points=10)) 4- create mesh TriangleMesh by using point cloud ball pivoting algorithm o3d.geometry.TriangleMes…

translate error: “an error occurred and dynamo crashed. we ask for apology”

My guess is that (Dynamo + Revit + CPython + Open3D + LargeDataSet) > the amount of RAM needed to process the model. Moving over to recap to preemptively clean the point clouds, or segment the points into smaller subsets is likely advisable. If you have a data set to share (just the point cloud file really) I can try and look into this later, but no promises as your Python code is quite specialized.

large point cloud file

14k points is large? I want to try that

[RMohareb]

@ruben.romero 14 k is not large. Also you can downsize the point cloud from recap when you export it to *.pts file

[ruben.romero]

@RMohareb

*.pys file

What fioe formats of point cloud can read Dynamo? I thought the point cloud link is RCP

[RMohareb]

.pts

What fioe formats of point cloud can read Dynamo?

Technically you can work with most formats if the standard is open, or if the authoring application has an accessible API. PTS is definitely the easiest to access though.

Thanks a lot for sharing the file.
Can you also share the pts file?
Is it possible to create a mesh with only a txt file containing x,y,z?

[RMohareb]

@rbasirat-wbi Mesh need also the vector. if you do not have vector in the pts file you can use Open3d to Vertex normal estimation

Hi @MiguelGT17 if you use PTS format the file already include the normal vector as shown in the below pic. if your file not include the normal vector you can use Open3d to estimate it. http://www.open3d.org/docs/release/tutorial/geometry/pointcloud.html#Visualize-point-cloud [TPS] [image]
