It appears that the arcpy.env.XYTolerance and arcpy.env.XYResolution settings do not influence the arcpy.3d.ExtractLas tool. Irrespective of the values assigned to these parameters, the outcomes remain consistent, suggesting that the default values (arcpy.env.XYTolerance = 0.001 and arcpy.env.XYResolution = 0.0001) are being utilized.
Therefore, it would be beneficial to enable the integration of arcpy.env.tolerance and arcpy.env.resolution settings within the ExtractLas Tool to enhance its versatility.
In my recent ExtractLas process, I identified that some las points are outside the designated Extraction Boundary (Optional). However, this issue wasn't present when using the Clip Tool with the same arcpy.env.XYTolerance and arcpy.env.XYResolution settings.
