01 / SKETCHING

Sketches, dimensions,
and constraints.

Draw a profile and add dimensions. Use constraints to keep lines parallel, connect endpoints, or control angles.

Lines, arcs, circles, splines, and construction geometry.
Dimensional and geometric constraints, with solver feedback.
Sketches on origin planes, offset planes, or supported planar faces.

02 / SOLID MODELING

Edit features
in the timeline.

Extrude or revolve a sketch into a solid, then add features such as fillets and shells. Edit an earlier feature to rebuild the model.

Solid features & limitations

Supported operations.

The feature guide covers extrude, revolve, sweep, loft, fillet, chamfer, shell, patterns, and other supported operations. Features can be edited, suppressed, renamed, reordered, or deleted.

Supported geometry varies by operation. See the feature guide and issue tracker for known limitations.

03 / PARAMETERS

Named parameters
and configurations.

Give dimensions names, calculate values with expressions, and use configurations to store variations of a design.

04 / ASSEMBLIES

Components and joints.

Organize components and occurrences, define joints, and inspect how parts fit into a larger design.

05 / SHEET METAL AND PLASTIC

Sheet metal
and plastic parts.

Work with rule-driven sheet-metal features and flat-pattern output, or use plastic-part tools for housing details.

Flat patterns and DXF export.

Sheet-metal workflows include flanges, hems, fold and unfold operations, flat patterns, and bend information. The v0.12.0 release adds improvements to flat-pattern DXF and conversion.

A flat pattern is a modeling result. Check material behavior, dimensions, tooling, and tolerances before fabrication.

06 / IMPORT AND EXPORT

Supported file formats.

Native files keep editable features and history. STEP and IGES carry geometry; mesh formats carry polygon meshes. Import and export support are listed separately below.

Source-reviewed format inventory; not independent testing of each release artifact
Format	Import	Export	Representation	Scope & limitations
SolidCraft / JSON	Open	Save / export	Native design	Editable features, parameters, and history. File-version compatibility applies.
STEP	Import	Export	B-rep geometry	Imported geometry becomes a base feature; another CAD app’s original history is not restored.
IGES	Import	Export	B-rep / surfaces	Supported solids or surfaces sewn into solids. Review import limitations.
STL / OBJ / 3MF	Mesh bodies	Export	Mesh geometry	Imported meshes are not automatically editable solid features.
DXF	See guide	Flat pattern	Sheet-metal outlines	Flat-pattern output does not imply a general-purpose drawing editor.
URDF	Not listed	Export	Assembly description	Assemblies and joints for robot simulators; review the exporter’s scope.

Based on documentation at revision 843c548 (October 15, 2026). Package compatibility has not been independently tested.
