not as smooth as Autocad on large projects but I really surprised how good it is. definitely worth a shoot. I'll be keeping eye on the future updates. and did I mention it's only 30mb!

Powerful Open Source Creative Softwares

Ever wondering about free great open source software to start your idea? Here's a list for you to get started. Also mentions several rarely known and newer software as well! Please note that almost none of these alternatives are 1-to-1 replacement with exact some features. Most of these software might have entirely different scope of project.

What is Open CAD Studio?

Open CAD Studio: a modern, Open Source 2D + 3D CAD application that reads and writes DWG and DXF natively built in Rust, with GPU-accelerated rendering.

Starts < 1 second. Size 30 MB

No license. No converters. No workarounds. Just open, draw, save.

What's in it: Full 2D drafting — LINE, PLINE, CIRCLE, ARC, ELLIPSE, SPLINE, HATCH, OFFSET, TRIM, EXTEND, FILLET, MIRROR, ARRAY, ROTATE, SCALE, EXPLODE… the entire AutoCAD-style command set

Native DWG & DXF (R13–R2018) read/write — the de-facto industry-standard format, without third-party library licenses

3D modelling with ACIS solids tessellation — BOX, SPHERE, CYLINDER, EXTRUDE, REVOLVE, LOFT, SWEEP, ARRAY3D — and 3DSOLID/REGION/BODY entities from DWG render correctly

Paper space + layouts — multi-tab model space, viewport projection with inline MSPACE overlay, VPORTS presets, plot styles (CTB/STB), PRINT directly to system printer

Full dimensioning — linear, aligned, angular, radial, diameter, ordinate + DIMSTYLE with everything (DIMASZ, DIMSCALE, DIMEXO, DIMEXE…) MLEADER, MTEXT, tables, GD&T tolerances, MLINE — with dedicated style managers

STL, STEP AP203, OBJ import/export, PDF plot, WBLOCK, XREF — everything you need to fit into an existing CAD chain GPU-accelerated via wgpu — scales smoothly to large models with many solids

Under the hood: Rust for memory safety and performance, iced for the UI, wgpu for the GPU rendering. Cross-platform: Windows, macOS, Linux. GPL-3.0 license.
