Cross-Section Studio

The figure every homework write-up needs and nobody wants to redraw: a true-to-scale 3-D pavement section with real layer thicknesses and eighteen procedural materials — FAA P-401 through P-501, SMA, OGFC, CTB, FDR, open-graded stone, clay and weathered rock. Build it, frame it, and copy the PNG straight to your clipboard — with or without a background — instead of hunting for a downloaded file.
