Zentek Studio

Zentek Studio is a free 2D drafting and 3D solid-modeling CAD application for Windows. It combines a full 2D drawing environment and a 3D modeler into one native desktop app with no registration, no accounts, no cloud lock-in, and pure local file storage.

2D Drafting Includes lines, arcs, circles, polylines, splines, hatching, text, blocks, and dimensions, supported by object snapping, layers, and exact keyboard coordinate entry.

3D Modeling Features primitives, extrude, revolve, loft, sweep, and push/pull, alongside boolean operations, shelling, edge fillets, and chamfers. Build models using precise analytic geometry with true curves or freeform meshes.

Interactive Design Draw directly in the 3D viewport using dynamic input fields, or drive your workflow via the command console. Seamlessly switch modes using the arrow keys, with step-based console hints guiding your next action.

File Compatibility Import: DXF, STL, OBJ Export: STEP, DXF, STL, OBJ, images, and printing

Prepare models directly for 3D printing, CAM workflows, or exchange with other CAD software.

Workflow & Performance Seamless Unit Switching: Work in millimeters or inches and switch anytime. Unit changes update the display representation without altering geometry scale. Auto-Recovery: Autosave background protection recovers your project if an application crash occurs. Lightweight: Ships as a single, self-contained binary with no runtimes or prerequisites to install.

System Requirements Operating System: Windows 10 or 11 (64-bit) Graphics: OpenGL 3.0 or higher
