SolveSpace can split intersecting entities via a separate tool. Users can make it active and draw basic primitives such as lines, circles, arcs, dots, and other points of references on the workplane, and constrain them to specific dimensions and relations. A workplane is plane with an origin for the new sketch where the SolveSpace draws entities. Modeling in SolveSpace is done by way of sketching in a workplane. When the model is complete, it is either exported to one of the supported CAD formats or into a document for further processing. The basic shapes of a new physical part is sketched out and constrained to specific dimensions and locations. SolveSpace workflow starts either with opening an existing file or creating a new one and usually involves sketching. SolveSpace is able to export models in STEP, STL, and G-code for reuse in third-party CAM software. Polygon meshes can be exported as STL and Wavefront OBJ NURBS as STEP. Wireframes can be exported as DXF and STEP files. SolveSpace v3.0 is able to export 2D sketches and surfaces into DXF/DWG ( AutoCAD version 2007), PDF, SVG, EPS, and HPGL file formats. The DXF/DWG file format AutoCAD (version 2007) is supported for opening and editing. SolveSpace can open and import its own textual *.slvs file formats for both editing and assembly. In 3D it is possible to use basic Boolean operations (union, difference, intersection), though as of version 3.0, SolveSpace had limitations on the order of application of these operations. 3D Solid Modeling Drawing, extrusion, rotation and revolution along a helix are supported in both modes. SolveSpace is shipped with the following basic features: 2D Sketch Modeling SolveSpace supports parametric 2D drawing of lines, circles, arcs, Cubic bézier curves etc datum points and lines are also supported for general, reference based modeling. SolveSpace is free and open source software distributed under the GPL-3.0-or-later license.
On September 22, 2020, Whitequark stepped down as a maintainer with the possibility of occasional contributions. The codebase at the time was about 30,000 lines of code and it took Whitequark almost 2 years to familiarize herself with it. In an 2020 interview article with a major maintainer named "Whitequark", SolveSpace was described as being very conservative in terms of backward compatibility. A previous software package called SketchFlat, also developed by Westhues, was replaced by SolveSpace. Development of SolveSpace started in 2008.
