C3D-DRAWSW · Draw Sidewalk done

Draws 1 straight-chord 3D polyline(s) from 10 SW points on layer SS-V-SIDEWALK.

C# payload

// Draw Sidewalk linework from surveyed points. Chained by point number, broken on gaps.
// Straight-chord 3D polylines on existing layer SS-V-SIDEWALK. Host owns Tx/ModelSpace.
