StepToSVG

Step to SVG opens STEP and IGES assemblies in your browser and exports clean vector line art for manuals, work instructions and technical drawings. It reads the exact edges of the CAD model and works out which ones you can see, so you get a real hidden-line SVG rather than a traced screenshot. Visible, tangent and hidden edges each get their own color and width. Lines are grouped by part, so the file opens cleanly in Illustrator, Inkscape, Figma or a documentation tool. You can also export a PNG render. Set up standard views, exploded views and sections yourself, or ask the AI assistant in plain language, for example to explode an assembly along a shaft, cut a section through the middle, or make a housing transparent. It can set colors, transparency and SVG line styles. One click undoes a change. Saved views can be exported again when the model updates. Your model never leaves your computer. Files are processed locally in the browser or the desktop app. The AI only sees a short summary of file and part names, sizes, positions and current settings, never the model file itself. It is free to use and does not require an account to start. Exports carry a small mark. Step to SVG Pro removes the mark and adds a Windows desktop app for very large assemblies, more section planes and a higher daily AI allowance (2 requests a day on the free account, 50 a day with Pro).

SupaVoxel

SupaVoxel is an AI 3D generator that turns a single image into a 3D model in seconds instead of hours. Upload a PNG, JPG or WebP up to 10 MB - a photo, a sketch, concept art or a screenshot - and SupaVoxel reconstructs the mesh and textures automatically, with no modeling skills or software installs required. Models can be previewed in the browser and exported as GLB, OBJ, STL, USDZ or 3MF for game engines, product mockups, AR scenes, 3D printing and classroom projects. The free tier includes 3 generations per day with GLB export and no credit card; paid plans start at $25 per year and add full textures, all export formats, a private commercial license and higher queue priority. SupaVoxel is used by indie game developers, product designers, educators and makers who need usable 3D assets quickly.
