OwlCAD Description

OwlCAD is a browser-based parametric CAD editor aimed squarely at 3D printing, giving hobbyists and makers real engineering tools without installing software or buying a professional license.

Designs are driven by dimensions you can revisit at any time; edit a number and the part updates. Solids combine cleanly, fit presets (press, slip, loose) account for FDM tolerances, and a print check points out overhangs, walls too thin to print and open meshes before anything reaches your slicer. Hollowing, lay-flat orientation and print weight and cost estimates help you prepare the part itself.

The toolset covers constrained 2D sketches, fillets and chamfers on individual edges, sweeps, lofts, patterns, datum planes, measurement, and assemblies with mates, an exploded view and a parts list. More than 30 generators build gears, threads, enclosures, hinges and Gridfinity storage. Bring in STEP, STL, 3MF, OBJ or OpenSCAD files; send out STEP, STL, 3MF, OBJ, GLB, DXF or SVG.

Your work autosaves locally and syncs to cloud projects with version history and share links. You can also publish a customizable model that others adjust and download. Whatever you design is yours to sell, prints and files alike, on every plan.

The editor is free. A Pro subscription adds AI that drafts either an editable parametric model or a sculpted mesh from a prompt, AI-assisted edits, and an MCP server so agents such as Claude Code or Cursor can model on your account. Pro users can bring their own provider key and skip credits. A desktop app is available too.

Open it and start designing; signing up is optional.

PolyWorks|Modeler Reviews
PolyWorks|Modeler
PolyWorks|Modeler™ is an all-encompassing software solution designed for reverse engineering, enabling the extraction of high-quality CAD entities, curves, surfaces, parametric sketches, and prismatic features from polygonal representations of scanned parts, which can then be utilized as a foundation for your advanced CAD modeling needs. The initial phase of the reverse-engineering process involves converting digitized point clouds into surface-based polygonal models, commonly referred to as meshes. These polygonal models are not only more compact and accurate but also less prone to noise compared to raw point clouds, making them suitable for industrial applications like milling, 3D printing, and aerodynamic simulations. It's crucial to implement effective scanning techniques that guarantee both quality and precision, utilizing real-time quality meshing technology. Users can enhance their models by filling in gaps, smoothing, and reconstructing surfaces, cleaning up boundaries, and recovering sharp edges to ensure surfaces are watertight. Additionally, users can extrude boundaries, offset surfaces, recreate fillets, and perform Boolean operations with CAD models, thus expanding the potential of their designs and applications. With these features, PolyWorks|Modeler™ significantly streamlines the reverse-engineering process, making it an invaluable tool for professionals in various industries.

A planetary gearbox from the built-in generator, with the 3D Print panel ready to check it or send a 3MF to Printables or MakerWorld. Every dimension is an exact value in millimeters. Parts combine with union and difference, and each one stays editable in the scene tree. Gridfinity generator: bins, baseplates and lids sized in grid units, with compartments and optional magnet or screw holes. Print check tints overhangs on the model and reports watertightness, thin walls, volume, surface area and center of mass. Browse community models and a parts library by category, then open any one to remix or import it.
