Hi All, Just thought I would chuck this out there for you all to experiment with, as I am looking to inlcude revised point cloud functionality in my next :snowflake: Sastrugi Package :snowflake: update :slight_smile: This graph takes an input XYZ list of pointcloud points, and sorts them into grou…

Woah! Been following your posts for awhile. This one is really impressive and incredibly useful.

@Ewan_Opie could you share your new Python RANSAC Code which doesnt need NumPy?

Hi folks, im looking to create one line on the centerline of pointcloud pipe but when i try to use any examples of sastrugi package they return null everytime. Can anyone explain to me how to avoid this? Thanks in advance (i’m already see the “How to Determine Centreline of a Pipe from Point Cloud…

Hi @diegorodriguesK33MF Can you post your graph, and point cloud sample for trouble shooting? There may be an issue with the projection of the clipping box which selects the points. If so, I can test this on Tuesday next week.

So I found it to #share . :+1: There are a few minor hoops to jump through to format your input point data, but hopefully everything is explained well enough. [Ransac IronPython Share] IronPython RANSAC Plane Detection Share.dyn (39.3 KB)

Hi Ewan, im stuck on this problem at the moment, when i use the “Select points by region” im getting no point info at all. I’ve see that the problem has ocurred with other people but i cant figure how to solve this by myself. Im from Brazil and here we use meters and mm as units (not feet), could y…

Hi @diegorodriguesK33MF I have made a minor revision to the code and updated the :snowflake:Sastrugi Package:snowflake: to v2.0.2 :slight_smile: [image] The nodes for Pointcloud selection look to have had a naming conflict within them that may have been preventing the output, and I have also fix…
