Solid modeling / parametric CAD / 3D solids
Create precise, editable 3D solids with sketches, constraints, feature history, drawings, CAM, and PDM.
solidSF is built for mechanical solid modeling: closed volumes, editable features, design intent, manufacturing drawings, and parts that can move from concept to production without turning into dead meshes.
Solid modeling is the CAD foundation for mechanical design. A solid model represents a part as an enclosed volume with measurable faces, edges, dimensions, and topology. Engineers use solid modeling to create brackets, housings, fixtures, mechanisms, molds, machined parts, sheet-metal parts, and assemblies that need to be manufactured.
That precision is why solid modeling is different from general 3D modeling. A mesh can look right but fail under a dimension change, tolerance stack, drawing export, or machining workflow. A solid model should survive edits because design intent lives in the feature tree.
| Need | Solid modeling | Mesh modeling |
|---|---|---|
| Precise dimensions | Native | Approximate unless heavily managed |
| Feature edits | History-based and parametric | Manual surface or vertex edits |
| Manufacturing drawings | First-class | Usually indirect |
| CAM and machining | Built for it | Often needs repair or conversion |
| Rendering and animation | Possible but secondary | Strong fit |
Browser solid modeling removes the install and licensing friction around a traditional CAD seat. A team can open the same model on macOS, Windows, Linux, ChromeOS, or iPad, and the workspace can still use local GPU acceleration through WebGPU and WebAssembly. That means the tool feels modern without giving up the core requirement: precise solid geometry.
solidSF also connects solid modeling to native AI agents. An agent can create a bracket, change a hole spacing, shell a body, or generate a drawing through the same CAD API used by the workspace. The result is still editable solid geometry.
Open solidSF and build a precise solid part in the browser. The useful test is simple: change the dimensions later and see whether the model still behaves.
