SolveSpace is not your typical computer-aided design (CAD) software; rather, it is an experience that is freeing, and the fact that it is free and open-source adds an additional layer of appeal to the product. Considering that I am someone who places a high value on both utility and versatility in design tools, SolveSpace has become my solution of choice. The constraint-based parametric design is one of the most notable elements of this product. This design enables a smooth integration of two-dimensional and three-dimensional modelling.
This makes it more than just a design tool; rather, it is a companion in the process of problem-solving because of the straightforward nature of its mechanical modelling capabilities, which lend a practical dimension to the creative process. The wonderful aspect of SolveSpace is its flexibility with multiple operating systems; regardless of whether I am working on my Windows computer, my Linux setup, or my macOS environment, it is always there to meet my creative requirements.
The ease of use that snap packages and native packages provide for a hassle-free installation experience is something that Linux users, in particular, would appreciate. For the purpose of importing and exporting files, the software is compatible with a variety of file formats, including STEP and DFX. Despite the fact that it saves models in its own proprietary.slvs file by default, the fact that it can export to a variety of formats, including PDF, SVG, and Encapsulated PostScript (EPS), ensures that my creations are not limited to a single ecosystem.
SolveSpace Specifications
SolveSpace is that fun. But I agree with this. I have used AutoCAD, Pro/E, Fusion 360, and other CAD/modeling program for a long time, but I don’t know much about FreeCAD. There may be something about the system’s simplicity that makes you feel like it only has the features you need to get the job done.

What is SolveSpace?
SolveSpace is the premier free and open-source computer-aided design (CAD) software. If you start using it, you will be able to enjoy stunning 2D and 3D designing at a minimal cost. The live dimensioned drawing of the solid geometry and the plane geometry may be delivered by it, and it can also prepare CAM data.
SolveSpace review: Features
Here are some of the most basic features that SolveSpace has: 2D drawing modelling Parametric 2D shapes like lines, circles, arcs, and cubic Bezier curves can be drawn in SolveSpace. In general reference-based modelling, datum points and lines can also be used. 3D modelling of solids It is possible to draw along a helix, extrude, rotate, and rotate in both ways. You can use simple Boolean functions in 3D, but since version 3.0, SolveSpace has limited the order in which they can be used.
Design and study of machines You can use the built-in constraint solver to see links on a flat surface or in space with pin, ball, or sliding joints, follow their movement, and save the results as CSV files. setting up You can load solids into SolveSpace in a special mode that doesn’t let you model them. It is possible to limit these imported solids to make sure that the designed model’s measurements meet the needs. Solid and flat shapes Instead of doing math or spreadsheets by hand, use live dimension drawings.
SolveSpace review: Workflow
Through the use of SolveSpace, you are able to quickly perform 3D modelling, which begins with the capability to open existing files or create new ones. It is common practice to begin the procedure by sketching at the beginning. In this section, users will briefly describe the fundamental geometry of the physical component. After that, these sketches are restricted to particular dimensions and locations, which guarantees that the design is accurate. Users have the ability to manage and improve the geometry of the model by utilising a variety of restrictions as the object takes shape.
Once the design is complete, SolveSpace makes it simple to convert it to CAD formats that are supported. Being able to easily add to larger projects or collaborate with other tools is made possible by this simplicity. Due to the fact that it is capable of performing a wide range of tasks, SolveSpace is an effective tool for rapidly creating and distributing detailed 3D models.
SolveSpace review: Sketching
SolveSpace’s modelling process is accomplished through the use of a technique known as sketching on the workplane. The entities that serve as the basis for new sketches are drawn on the workplane in SolveSpace. The workplane is the plane on which drawing is performed. After activating it, users will have the ability to create fundamental primitives on the workplane, such as lines, circles, arcs, points, and other reference points, and then constrain those primitives to specific dimensions and relationships.
Also, they will be able to draw other reference points. The division of overlapping entities can be accomplished by SolveSpace through the utilization of a wide range of tools. Users are able to add snap points to the grid that they manage. There is no limitation whatsoever placed on the number of work planes that a user is able to generate from within the software for themselves.
SolveSpace review: 3D modeling
It is possible to extrude the sketch into a volumetric model in order to continue modelling the three-dimensional component after the sketch has been finished. Further modelling of the component is now possible as a result of this. Some groups are formed along the normalcy that are provided by models that are extruded. These groups are produced along the normals.
Each of the groups in SolveSpace contains actions that are carried out on a particular sketch that was developed for a certain 3D activity. SolveSpace is organized into groups, and action items are contained within each of those groups. The actions that are included in these actions include the processes of extrusion, rotation, and translation.
Once the three-dimensional model has been developed, it is possible to further constrain it by making use of the fundamental tools that were stated earlier in this paragraph. Furthermore, by utilising Boolean operations, it is feasible to mix it with other models. Both of these possibilities are possible. Additionally, it is possible to draw a work plane on a particular “surface” of a different 3D model on the computer. This is called “surface drawing.” Users are able to take advantage of this opportunity. In general, the depiction of a surface is composed of two line segments that are joined to one another by a point. These line segments are connected to one another by a point.
SolveSpace review: Limitations
A disclaimer is included in the SolveSpace documentation as of version 2.1, which states that there is limited support for NURB surface Boolean operations, which may on occasion fail. As of version 3.0, SolveSpace does not have the capability to chamfer or fillet 3D solid bodies. However, there is a method that may be used to manually generate it.
The creation of fillets in the form of tangent arcs at corner points is one method for creating 2D sketches. SolveSpace is appropriate for CAM models that are straightforward, but it is not ideal for more complex models. Over the course of the journey, there is no extrusion.
Final Words
As I started my own journey with SolveSpace, I found a 3D parametric modelling program that was not only as flexible as I thought it would be, but also surpassed my hopes. This software became an important part of my design work because it had both easy-to-use features and powerful modelling tools. I realized that SolveSpace was carefully made with users of all skill levels in mind, from people who are new to 3D modelling to experienced artists who want more advanced features.
SolveSpace review: The Good and Bad
A previous software package known as SketchFlat, which was also developed by Westhues, was decommissioned and replaced by SolveSpace. With the release of version 1.9 in 2012, the software was made available as unrestricted freeware proprietary software. Additional support for Linux and MacOS was included in version 2.1. It is the goal of SolveSpace to be as backwards compatible as is humanly practical.
The Good
- Robust 3D modeling capabilities
- Parametric design for flexible modifications
- Seamless 2D drafting features
- Intuitive assembly modeling
- Powerful constraint solver for design accuracy
The Bad
- Learning curve for beginners
- User interface could be more modern
- Limited advanced rendering options
Questions and Answers
Simply dragging a spot on the new surface will allow you to know the extrude depth as well as the direction in which the extrude occurred. Once the extrusion depth appears to be approximately correct, it is possible to specify it precisely by making use of restrictions. One of the newly extruded edges, for instance, could have its length restricted depending on the user’s preferences.
The letter “REF” is applied to the length or angle that is being shown in order to create a reference dimension. Because the dimension is provided by the geometry and not by the user, it is not useful to write in a new value for the reference dimension. Double-clicking a reference dimension does not accomplish anything.
