Summary

Prompt

Make a cross-shaped frame in the XY plane by fusing two rectangular bars at right angles. Bar A is 100mm long along X, 20mm wide along Y, and 10mm tall along Z, centered in X and Y with its bottom face on the XY plane (so it spans x in [-50, 50], y in [-10, 10], z in [0, 10]). Bar B is 20mm wide along X, 100mm long along Y, and 10mm tall along Z, centered in X and Y with its bottom face on the XY plane (so it spans x in [-10, 10], y in [-50, 50], z in [0, 10]). Union the two bars into a single plus-sign-shaped solid; the central 20mm × 20mm × 10mm overlap is counted only once. Output a single solid.
