Last updated: October 21, 2026 · Built on the open-source Pascal editor · Free on all plans
What You Can Build in MNKI 3D Sandbox
1. Sketch Buildings in 3D
Draw walls, slabs, doors, windows, stairs, and interior furniture directly in your browser — no desktop CAD/BIM installation required.
2. Sun Study & Walkthrough
Switch to Present mode to evaluate natural daylight with an interactive sun study and walk through rooms from human eye level or elevated axonometric angles.
3. Export DXF & PDF Drawings
Use the toolbar's Export DXF and Export PDF dialogs to choose which floor levels and section cuts to include, or open the exported DXF directly in MNKI EasyCAD.
4. Render in 4K with MNKI Studio
Capture any viewport angle and render it in MNKI Studio using the 3D Massing, White Model, or 3D Plan module across 30+ architectural styles.

Frequently asked questions
Is MNKI 3D Sandbox free to use?
Yes. MNKI 3D Sandbox is included in MNKI's Free plan at no credit cost. You can draw walls, place doors, windows and furniture, walk through your 3D building, run a sun study, and export DXF and PDF drawings.
Can MNKI 3D Sandbox export CAD (DXF) and PDF drawings?
Yes. The viewer toolbar includes Export DXF and Export PDF buttons, and the export dialog lets you choose which building levels and section cuts to include. You can also send exported plan drawings into MNKI EasyCAD to add 2D annotations, hatches and dimensions.
How do I turn my 3D Sandbox model into a photorealistic AI render?
Capture any perspective, axonometric or elevation view in 3D Sandbox and send or upload it to MNKI Studio (using 3D Massing, White Model or Perspective View input) to render it in up to 4K across 30+ architectural styles.
