Dimviz vs KeyShot
Use KeyShot when you need photorealistic marketing imagery of an arbitrary 3D model and already have the geometry. Use Dimviz when the subject is a profile — an extrusion, pultrusion or rolled section — and you need a render plus a verified engineering datasheet generated from the dimensions, without building or importing a 3D model.
Both make images of products, but they solve different problems. KeyShot is a general-purpose photoreal renderer; Dimviz is a deterministic profile-asset generator. Here is how they line up for anyone specifying or marketing extruded and pultruded profiles.
| Feature | Dimviz | KeyShot |
|---|---|---|
| Primary job | Profile render + engineering datasheet | Photorealistic rendering of any 3D model |
| Input | ◆Section dimensions / CAD / photo — no 3D model needed | Requires an existing 3D model (STEP, OBJ, etc.) |
| Dimensional truth | ◆Silhouette is the exact section; properties computed | Looks right, but not tied to verified dimensions |
| Section properties | ◆A, Ix, Sx, weight/m computed automatically | Not an engineering calculator |
| Photorealism | Real-time PBR 3D (PNG export), non-photoreal | ◆Industry-leading photoreal materials & lighting |
| Arbitrary geometry | Profiles / constant sections only | ◆Any shape, any complexity |
| Catalog consistency | ◆Every size shares one template automatically | Manual scene setup per part |
| Time to first asset | ◆Seconds, in the browser | Model import + scene setup |
| Cost | ◆Free tools; paid generation | Commercial licence |
Where KeyShot wins
For a hero shot of a complex assembly with realistic metal, glass and lighting, KeyShot is superb and Dimviz doesn't try to compete. If you already have the 3D model and want a photoreal image, that's KeyShot's home turf.
Where Dimviz wins
When the subject is a profile and the audience is an engineer or a specifier, the render has to agree with the dimensions — and you usually want the section properties alongside it. Dimviz produces both from the geometry with no modelling step, and does it identically across an entire size range, so a 40-size catalog looks like one product family.
Can they work together?
Yes. Use Dimviz for the fast, dimension-true catalog images and datasheets, and reach for KeyShot when a specific flagship product needs a photoreal marketing render. They cover different points on the speed-vs-photorealism curve.
FAQ
Is Dimviz a KeyShot alternative?+
For profiles, yes — if you need a clean, dimension-true render and a datasheet from section dimensions without building a 3D model. For photorealistic rendering of arbitrary geometry, KeyShot remains the stronger tool.
Do I need a 3D model to use Dimviz?+
No. Dimviz builds the geometry from the profile's cross-section dimensions (or a CAD/photo of the section), so there's nothing to model or import.
Is Dimviz cheaper than KeyShot?+
Dimviz's core tools are free and generation is low-cost; KeyShot is a commercial rendering licence. They target different jobs, so cost isn't the only factor.
