Deleting points with Orthomosaic showing as XY Plane Basemap?

[jazzyj]

I've been able to use the ground classification tool to remove about 80% of above ground objects. I have some areas of shrubs that I want to remove all points within the edges of the shrubs.  I've of course tried about 6 or more iterations of the ground classification tool using difference settings but it would just be easier to manually delete the points in the area of the shrubs.  Howver I can't get the point cloud and orthomosaic view to sync together so when I move the view in the X/Y plane it moves the view for both the layers.  Nor can I figure out how to select points while being able to view the orthomosaic as a base layer in the X/Y plane when editing the point cloud.  Is there anyway I can accomplish this?

So far it looks like the best I can do is delete vertexes from the contour polygons inside the bushes but this isn't optimal.  Also is the controur export a 2D or 3D DXF?
