01 / SKETCH

Constrain your sketch.

Set dimensions, angles, and geometric constraints.

02 / BUILD

Build a solid.

Extrude or revolve a sketch into a 3D part.

03 / REFINE

Edit earlier features.

Change parameters and rebuild the model.

04 / EXCHANGE

Import and export files.

Save editable designs or export STEP and mesh files.

PARAMETERS AND FEATURE HISTORY

Change dimensions.
Rebuild the model.

Use named parameters for dimensions such as board width, wall thickness, and enclosure height. Change a value to rebuild the features that depend on it.

Start with a constrained sketch.

Define the sketch’s dimensions and geometric constraints.

Add features to the timeline.

Keep the sketch, features, and parameters in an editable timeline.

Change the enclosure height.

The recorded enclosure changes from 24 to 32 mm in height.

AI AGENTS / MODEL CONTEXT PROTOCOL

Model with an AI agent.

MCP lets a compatible AI agent run modeling commands, measure geometry, change parameters, and export files. You can open and edit the resulting design in SolidCraft.

AI is optional. SolidCraft works without a connected assistant.

MODELING TOOLS

Sketch, model, and assemble.

Explore the features

Sketches and constraints.

Draw lines, arcs, and splines, then add dimensions and constraints.

Solid modeling.

Extrude, revolve, fillet, and edit features in the timeline.

Assemblies and joints.

Combine components, define joints, and create configurations.

Import and export.

SOLIDCORE / GEOMETRY KERNEL

SolidCore.
A Rust geometry kernel.

SolidCore is a Rust port of SMLib, NVIDIA’s open-source C++ geometry library. A geometry kernel represents 3D shapes and performs modeling operations on them.

About SolidCore

SolidCore is being developed for use in SolidCraft.
