Creating topo from CAD (.dwg) file w/ spot elevations

Hello everyone, I am new to Sketchup (3-4 months) and have run into a problem. I need to make a topo surface (Of existing hillside) that I can place my model onto. I have a CAD (.dwg from my civil engineer)file that has spot elevations x,y,z axis(located in 1 of 20+ layers)but no contour lines. Can anyone please explain how I get these spot elevations into a topo surface?

I have tried messing around with "TIG Triangulate Points plugin" but no luck.
I imported CAD file in Sketchup
Deleted all layers leaving only the layer with spot elevations (Layer 0)
Attempted to use plugin on spot elevations - received "No Guide Points in the Selection!"
Noticed spot elevations were actually circles w/ lines in them
Attempted to edit spot elevation (component) to a guide point (this is where I am stuck)
I hope that once all 163 spot elevations are converted to "guide points" the plug in will work.

not sure if I am even started in the correct direction. please help
