Exporting

Getting the drawing out - pictures, film, and shapes.

Ctrl+E, or /export.

Pictures

PNG - any size, or one of the ready-made sizes for wherever you are posting it. It can have nothing behind it, so it drops onto a page cleanly.
JPEG - smaller, and always on a solid background.
WebP - a little film that swings around the model, lossless, so every line is as sharp as it is on screen. See recording a move.

PDF plans

Choose PDF in the export dialog, then the paper, portrait or landscape, and print scale. ISO A0–A5, ANSI A–E, ARCH A–E and E1/E2/E3, Legal and Engineering F are available. The drawing's print scale is selected initially. The preview shows the drawing area: right-drag to position the drawing. Anything outside it is cropped; it is never silently shrunk to fit.

Use PLAN or a square-on elevation for measurable plans. A turned view shows projected lengths. The PDF includes a matching scale bar, 10 mm margins and a footer. Print using 100% / Actual size, not Fit to page.

PDF uses the same vector geometry as SVG: lines, segmented arcs, face outlines and holes, notes and dimension labels. It stays sharp when enlarged, and text remains selectable. Like SVG, it exports entities in drawing order, not the shaded screen renderer's hidden-line result. The preview is a framing view; shading and hidden edges can differ. Output is one sheet; tiling is not implemented yet.

Lines

SVG - this view as vectors, at true size. The file says how many inches or millimeters across it is, so it opens at the right size in a drawing program, at a print shop, or on a cutting machine, with nothing to scale by hand. Export from PLAN and the size on the paper is the size of the thing.
DXF - this view flat, or the whole model in three dimensions, for somebody else's CAD.

Shapes to print

STL - triangles in millimeters, which is what a 3D printer's slicer wants. It tells you whether the shape is closed before you find out from the printer.
OpenSCAD - a polyhedron per solid, to cut and union in OpenSCAD.

Both arrive centered on the bed and sitting flat on it - centered across X and Y, bottom at Z zero - which is where a slicer expects to find a thing. There is nothing to move before printing. See solids and 3D printing for what makes a shape printable in the first place.

PDF support uses Free Pascal's library with its linking exception and library license. The application remains MIT.
