FLATTENSOLID

FLATTENSOLID projects 3D solids onto the XY plane (Z=0) as flat 2D geometry made of lines and arcs. Use it when you want a flat drawing from a 3D model, for example a top view as a line drawing.

Starting

Type FLATTENSOLID on the command line, or use the button in the ribbon on the SCAD Draw / View tab, Mesh / Solids panel.

How it works

1. Preselect the objects, or pick them when the command asks (the standard BricsCAD selection prompt).
2. Each object is broken down into separate faces and then into lines, arcs and polylines. These are projected onto the XY plane (Z=0). Splines are converted to a line (if they are straight) or a polyline.
3. Duplicate pieces of geometry are not added twice. OVERKILL is then run automatically on the result.
4. The command reports Flatten complete: N entities added, M duplicates filtered.
