Export & Share

Carcassist exports to several formats — from the project file through CAD/3D to CSV and PDF/DXF — and can share a plan via link.

3D export (button in the 3D view)

The 3D export menu offers three 3D formats:

What it does: Creates parametric BREP solids via the replicad/OpenCascade kernel — true solids, not triangle meshes. The bodies are named in the surface language and folded into an assembly structure that follows the parts list: one sub-assembly per carcass (plinth/worktop standalone), with a folder per role inside (side, bottom …); the parts of a drawer form their own "Drawer N" sub-assembly.
When to use it: Further processing in FreeCAD/Fusion and others — opens there as a clean component tree.
Pros & cons: Fully CAD-capable (dimensions, boolean machining). The export loads a several-MB 3D kernel (WASM) only on demand and shows a progress bar (load kernel → build bodies → write STEP). The joint clearance controls the fit of the joinery in the STEP.

What it does: A triangle mesh of the model.
When to use it: 3D-printing slicers and the free SketchUp web app (the only 3D format it imports).
Pros & cons: Readable everywhere, instant (no CAD kernel); unitless — on import choose "as millimeters". No parametric geometry.

In the toolbar (or the mobile menu):

Export (JSON): Saves the entire project as a .json file.
Import (JSON): Loads such a file back in.
Pros & cons: Lossless, complete backup/handover of the plan; usable only in Carcassist.

For spreadsheets, ordering, or handover to a cutting service.

In the Drawing tab: Print / PDF (multi-page scale drawing) and DXF (CAM) for CNC/CAM processing.

What it does: "Share" saves the project server-side under its ID and copies a link to the clipboard. Whoever opens it sees exactly your project.
Note: Every plan is continuously saved locally and server-side anyway (the ID is in the address bar) — "Share" only makes sure the server-side state is current, and hands you the link.
