I’m having an issue when I render topo of anything that is in the air basically. I can’t figure out how to stop rendering topo lines in an area where there isn’t anything. I always get contour lines from the top of the structure to the ground, no matter the elevation change. And the topo that I do get always has spikes in elevations.
That’s the way they look. I would like to have 0 contour lines between the bottom of the structure and the ground, so that when I go into 3D view in CAD I would be able to differentiate the structures from their surroundings. Also, what is causing the spikes in the tops of the structures? Everything around them are in good shape, but no matter what they always spike like that.
