Make SolveSpace parts, assemblies, and linkage positions easier to present.
Open-source parametric 2D and 3D CAD for constrained sketches, solid parts, linked assemblies, mechanism studies, and fabrication-oriented exports. SolveSpace users can build compact mechanical designs with extrudes, lathes, helixes, and Boolean operations, then use a clean model view to explain the finished form.
Open-source parametric 2D and 3D CAD for constrained sketches, solid parts, linked assemblies, mechanism studies, and fabrication-oriented exports. SolveSpace users can build compact mechanical designs with extrudes, lathes, helixes, and Boolean operations, then use a clean model view to explain the finished form.
SolveSpace is a strong starting point for visualizing compact mechanical work that begins with constrained sketches and becomes a solid part, a linked assembly, or a mechanism study. A designer may use it for a bent bracket, printable enclosure, small fixture, linkage, or set of interlocking parts, then choose a view that makes the working geometry understandable. Its assembly workflow can link files and position parts with constraints, while its mechanism tools can help identify a meaningful open, closed, or intermediate position. RENDERCAD can turn that prepared SolveSpace viewport into a clearer product-style image for a concept review, build guide, portfolio, product explanation, or customer conversation. It is especially useful when the viewport already establishes the correct silhouette, hole pattern, moving-part position, and assembly relationship, but needs more deliberate lighting, material cues, and a presentation-ready background. The resulting image should communicate the intended design, not replace the CAD model or validate fit, clearance, dimensions, or mechanism behavior.
First, solve the sketch and complete the part or linked assembly in SolveSpace. For an assembly, set the constraints and select a position that clearly shows how the parts relate; for a linkage, use a representative mechanism position rather than a cluttered in-motion view. Choose an isometric or orthographic camera that keeps important faces, openings, and interfaces visible. Hide dimensions, construction geometry, workplanes, and unnecessary entities, then capture a clean shaded viewport image with a simple background. Submit that view to RENDERCAD with a concise description of the intended material and presentation context, such as anodized hardware, molded plastic, or a workshop-ready fixture. Review the output against the SolveSpace viewport and return to the CAD model for every geometric or engineering decision. Use the finished visual beside drawings, measurements, or CAD exports when those remain authoritative.

RENDERCAD uses a maintained selection of image-generation models for different rendering tasks. Results can vary by model and input, so compare generated output with the source design before relying on geometry, materials, or dimensions.
| Feature | RENDERCAD | SolveSpace |
|---|---|---|
| Engine | Generative AI | Parametric 2D and 3D CAD with constrained sketches, extrudes, lathes, helixes, Boolean operations, linked assemblies, and mechanism analysis |
| Output | Images + Video | 2D drawings and vector exports, shaded image views, triangle meshes, and CAD exchange geometry for fabrication or downstream visualization |
| Resolution | HD / 4K | Viewport and export resolution depend on display settings, export format, and any downstream visualization tool |
| Image Speed | Image renders complete in 60 seconds. | SolveSpace focuses on interactive CAD modeling; photorealistic rendering is usually handled outside the core modeling workflow |
| Video Speed | Videos complete in 2-5 minutes. | Mechanism studies can inform a sequence of presentation frames, but video rendering is not a primary SolveSpace output path |
| Scene Set Up | No separate local scene | Complete the part or linked assembly, choose the visible groups and a clear orthographic or isometric view, then use RENDERCAD when the shaded viewport needs product-style lighting and material definition |
| Input | Screen Snip | SolveSpace files based on constrained sketches, workplanes, solid features, imported geometry, linked parts, and assemblies |
| Hardware | Cloud GPU | Desktop CAD workflow on supported Windows, macOS, and Linux environments, with package options varying by platform |
| Install | None | Open-source desktop installation from official releases or supported package channels, depending on operating system |
| Cost | from $9/mo | Free and open-source software distributed under the GPLv3 |
Read the numbers. We trust you to know theirs.
Skip a separate local scene build. Pick a condition, material, and background while RENDERCAD handles the image-generation step. Image renders complete in 60 seconds.

Get StartedCommon solutions for SolveSpace users
Mask the visible label area and attach authorized artwork as a reference to guide the generated mockup. Verify spelling, shape, color, placement, and perspective; add exact production artwork afterward in a graphics or packaging-design tool.
Reuse the same source image with authorized daytime and night lighting references or instructions. Compare both outputs with the source because lighting changes can also alter generated details.
Upload a clear image, choose the Realistic engine, and describe the intended glass type, tint, and lighting. Transparency and reflections can vary between generations, so inspect the output before use.
Add phrases like "Light from left," "Backlit," or "Top down lighting" to your custom prompt in RENDERCAD.
Yes, use the "Details" field in the video tab to describe elements like "Steam rising" or "Lights flickering."
Submit a clear viewport screenshot to the web workflow instead of running a local scene render. The generation request runs in the cloud while your source application remains separate.
Open the current desktop app or browser extension, select the viewport region, and send the captured image into the screenshot-based workflow. Availability and device requirements are documented on the current download pages.
Add a familiar scale cue such as a person, hand, or furniture item, then verify the generated relationship against known dimensions in the source model.
It supports fast visual feedback from a clear viewport capture. Image renders complete in 60 seconds.
The current desktop app or browser extension can capture a selected viewport region and send that screenshot into the image workflow. The web upload path remains available without a CAD plugin.
Choose a background or describe the intended environment and lighting. Generated reflections and illumination are visual interpretations, not a scene-based light simulation.
4K is an optional output-resolution step. It increases pixel dimensions but does not restore missing source detail or guarantee print suitability.
