Zlim vs CADfix VIZ at a glance
| Zlim | CADfix VIZ | |
|---|---|---|
| Focus | Any format → optimized GLB | CAD B-Rep → glTF specialist |
| CAD input | STEP, Creo, CATIA | STEP, CATIA, NX, SolidWorks, Creo, Inventor, JT… |
| Non-CAD input | FBX, USD/USDZ, STL, OBJ, PLY, 3MF, glTF | CAD-focused |
| B-Rep repair / healing | Tessellation-bounded cleanup | Advanced (stitching, error correction) |
| LOD | Preset-based output | Automatic multi-level LOD |
| Interfaces | Hosted API, local CLI, MCP server | Desktop / enterprise tooling |
| Determinism / reporting | Byte-stable + per-job metrics | Configurable pipeline |
| Pricing | $0 / $29 / $149 per month | Enterprise (custom / contact vendor) |
| Best for | Broad-format automated optimization | Deep B-Rep repair on pure-CAD data |
What is CADfix VIZ?
CADfix VIZ is the visualization-focused member of the CADfix family from ITI (a Wipro company). It takes native and neutral CAD — CATIA, NX, Creo, SolidWorks, Inventor, STEP, Parasolid, JT — and produces glTF/GLB through a configurable pipeline: import, tessellation tuning (polygon density, chord tolerance), advanced B-Rep repair, automatic LOD generation, and Draco-compressed export. It's built for engineering-grade CAD where clean tessellation and geometry repair matter.
How Zlim is different
CADfix VIZ goes deeper on CAD B-Rep specifically — repair, healing, and fine tessellation control that a pure-CAD workflow benefits from. Zlim goes broader: it optimizes CAD, but also FBX, USD, STL, OBJ, and glTF, through one API/CLI/MCP interface with deterministic, reported output and public pricing.
If every input is complex B-Rep CAD needing repair, CADfix VIZ's specialization is valuable. If your inputs are mixed — CAD plus meshes and DCC files — and you want an automated, developer-first optimizer with transparent pricing, Zlim fits better.
When to choose which
Choose CADfix VIZ for pure-CAD pipelines that need advanced B-Rep repair and precise tessellation control.
Choose Zlim for mixed-format, automated CAD/FBX/USD/STL → GLB via API, CLI, or MCP, with deterministic output and self-serve pricing.
FAQ
Does Zlim repair broken CAD geometry like CADfix?
Zlim tessellates and cleans CAD to produce a valid optimized GLB, but CADfix VIZ offers deeper, dedicated B-Rep repair (stitching, error correction, normal alignment) for problematic engineering CAD. For heavy repair on pure-CAD data, CADfix specializes; for broad-format automated optimization, Zlim is the fit.
Which handles non-CAD formats like FBX or USD?
Zlim. It ingests FBX, USD/USDZ, STL, OBJ, PLY, and 3MF in addition to CAD, all to optimized GLB. CADfix VIZ is focused on CAD B-Rep input.
Is Zlim API-first?
Yes — Zlim is a hosted REST API plus a local CLI and an MCP server, so it drops into automated pipelines and AI agents. CADfix VIZ is oriented around desktop/enterprise CAD tooling.
