I'd like to draw a vertical soil-bentonite slurry wall in 3D. To test the polyface I used the file below.
4 139807.0 583117.0 25.039922.0 583248.0 25.039922.0 583248.0 -10.039807.0 583117.0 -10.01 2 3 4 1
Nothing shows up. I can draw a polyline with the same coordinates.
I'll look into this and get back to you shortly.
