Solid Body Export

At a glance

STEP AP214 — exact B-Rep geometry, mm or inches. Opens in any CAD tool.
STL — tessellated mesh for 3D printing. Binary or ASCII, mm or inches.
3MF — compressed mesh archive for modern slicers.
Right-click any body in the browser panel → Export

Any solid body can leave JetCad3 as a real CAD or mesh file: right-click the body in the browser panel and choose Export. A small dialog picks the format — the last-used format is remembered — and the unit selector defaults to Settings → Preferred Units on every export.

STEP — exact geometry

STEP (AP214) writes the body's true B-Rep straight from the OpenCascade kernel — exact cylinders, planes, and curves, not a mesh — in millimeters or inches. This is the format to hand a machine shop, a customer, or another CAD system; it opens cleanly in Fusion 360, SolidWorks, FreeCAD, and everything else that reads STEP.

STL and 3MF — meshes for printing

STL exports the tessellated mesh in Binary (compact, the default) or ASCII encoding, in mm or inches, Z-up. 3MF packs the same mesh into a compressed archive that carries its own unit metadata, so slicers import it at the correct size with no unit guessing — if your slicer accepts 3MF, prefer it over STL.

Sketches export separately as DXF or SVG from the same browser-panel right-click — see Sketch Import & Export.
