Solid modeling / parametric CAD / 3D solids

Solid modeling software in the browser

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.

What solid modeling means

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.

Parametric solid modeling workflow

01
Sketch and constrain
Define profiles with dimensions, relations, construction lines, and equations.
02
Build solid features
Extrude, revolve, sweep, loft, shell, fillet, chamfer, pattern, mirror, and cut.
03
Release the part
Create drawings, CAM setups, part numbers, revisions, and project records.

Why browser solid modeling matters

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.

FAQ

What is solid modeling?
Solid modeling is a CAD method for representing a 3D object as an enclosed volume with faces, edges, features, and measurable geometry that can be manufactured and inspected.
How is solid modeling different from mesh modeling?
Solid modeling stores precise faces, edges, dimensions, and feature history. Mesh modeling stores polygon surfaces, which are useful for visual assets but weaker for mechanical edits, drawings, tolerances, and manufacturing.
Does solidSF support parametric solid modeling?
Yes. solidSF supports sketches, constraints, dimensions, feature history, assemblies, drawings, CAM, and PDM in a browser workspace.

Start solid modeling

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.
