Complex sketches need disciplined constraint management
How to use it well
Start with a simple sketch and add only the constraints needed to express the design intent. Check remaining degrees of freedom before extruding or assembling parts. Make a small dimension change to test whether the model behaves as expected, and verify exported geometry in the tool that will use it downstream.
This is best suited to mechanical concepts and small parametric designs. Before committing a larger project, account for these trade-offs: less extensive than large CAD suites; complex sketches need disciplined constraint management.
A few things you might be wondering.
Is SolveSpace free?
The GPLv3 software is available without a license subscription and includes Constrained sketches and Parametric solids. This covers the downloadable application, while optional support, third-party services, and separately licensed materials have their own terms.
Can SolveSpace use dimensional constraints?
Yes. Constrained parametric sketches are a core capability.
Should every sketch be constrained arbitrarily?
No. Use constraints that express the intended geometry without contradictory restrictions.
Where can I check the latest prices?

How should I compare this tool with alternatives?
Choose tools for the same task, then compare their feature limits, platform support, and total cost for your team. The Compare button helps you keep a shortlist.
Are the user reviews moderated?
Yes. New reviews are submitted for moderation. We show published user reviews separately from the editorial overview and never assign a default user rating.
LibreCAD is a two-dimensional CAD application for creating technical drawings with layers, dimensions, and standard drafting tools. It serves users who need editable 2D geometry without a subscription, while remaining distinct from full parametric 3D modeling systems.

OpenSCAD creates solid 3D models from scripts that describe geometry and transformations. It is particularly useful for dimension-driven parts and repeatable variants, offering a code-centered modeling workflow rather than a conventional interactive sculpting or drawing interface.

BRL-CAD is a solid-modeling system with geometry editing, ray tracing, and analysis tools. Its long-established constructive geometry workflow serves technical users who need explicit solid models and computational geometry capabilities rather than a purely artistic modeling interface.
