Modify densified point cloud ? (delete parts)

 how can i remove/delete the trees in my model ?  When i calculate the volume, part of the trees are include in the volume.  See picture :

I already tried to remove them in the raycloud with succes (edit densified pointcloud and assign to ‘delete’)

Then reprocessed step 3.  But when i go back to ‘volume’ the trees appear again.

Can someone explain what i do wrong ? 

(Sorry for my english)

Hi Herman,

Typically, after the points are assigned to the “Disabled” class and Step 3 is reprocessed, the removed points should not be included in the volume measurements. 

Can you confirm that all the steps from this article were completed: How to remove Objects from a Stockpile for the Volume Computation?

Best,
