Is there a feature that can rutomatically remove objects/trees from DEM data ?

You need to do the classifying in the point cloud - either with the automatic process, manually or both.  Then from workflow "build DEM" and select the point classes to build the DEM from.  If you just select the ground classified points you will have a DEM without trees etc in it.

Thank you.
So I classified the point cloud, visually, , by color, I see only houses/buildings , on top of brown (ground level) and no low (<1m vegetation)
Is there a way to display all detected classes, one by one ?
