Use Section extraction tool from Command Line or with CloudComPy

[pizzettix]

Hi,

Given a point cloud and multiple polylines I want to perform an extraction as done with the "Segmentation -> Extract Sections tool", to obtain the points falling under/over the different polylines. I want to do it programmatically with CommandLine or CloudComPy and export the "Colud slice" in diferrent txt files for every polyline.
At the moment I find a workaround with CROP command in the CommandLine (I do an offset of the width/2 and get the coordinates of the closed polyline-rectangle), but the execution is very slow, because for every polyline the CloudCompare load the initial point cloud every time.

Any advice or different solutions?

Probably CloudCompy should give you more options... But I don't know it well enough. You could ask here: https://github.com/CloudCompare/CloudComPy/issues
