Everything you need to draft and model

One tool for 2D drawings and 3D parts — precise, fast, and entirely on your machine.

✏️

2D drafting

Lines, arcs, circles, polylines, splines, hatch, text, blocks and dimensions — with object snapping, layers and exact keyboard input.

🧊

3D solid modeling

Primitives, extrude, revolve, loft, sweep and push/pull, plus booleans, shells and edge fillets & chamfers.

🎯

Exact or mesh

Build precise analytic bodies with true curves, or freeform meshes. (Analytic bodies are still work in progress).

🔄

Import & export

Import DXF, STL and OBJ.
Export to STEP (exact surfaces), DXF, STL, OBJ, images and print. 3D‑printing ready.

📐

Real units

Work in millimetres or inches and switch anytime — your geometry never changes, only how it reads.

💾

Yours & offline

A native desktop app. Files stay on your machine, and autosave recovers your work if anything crashes.

It's a public beta — and it's free. Expect the occasional rough edge. Your work is saved automatically and recovered after a crash, and you can send feedback or suggestions any time from Help ▸ Report a Bug/Suggestion in the app, or email support@zentekstudio.com.

Contact us

Questions, bug reports and suggestions all go to the same place.

Found a bug, hit something confusing, or want a feature? Tell us. During the beta that feedback is the most useful thing you can send. You can also report from inside the app under Help ▸ Report a Bug/Suggestion, which attaches your version automatically.
