CADfix removes the barriers that prevent re-use of solid models. By providing an extensive set of geometry manipulation tools for importing, repairing and exporting data, CADfix maximizes the re-use of CAD data in downstream applications.
By detecting and repairing a range of CAD geometry issues, our user-friendly wizard interface ensures that the model is correctly defined and suitably flavored for the downstream application. CADfix also offers model de-featuring utilities, which are popular with CAE analysis users who require automated de-featuring operations.
CADfix is packaged as a desktop or server solution, with extensible modular functionality dependent upon the end user’s source and target systems. The application may be integrated into PLM or workflow automation tools. CADfix also serves as a pre-processor within proprietary CAE-centric OEM applications.

CAD re-use for CAE
CADfix offers CAE analysts the ability to automatically and interactively repair and transform CAD geometries prior to analysis and ensures that solid or surface models are translated effectively into target systems. In addition, CADfix offers a full range of import and export functionality for pre-processing CAD data from native and neutral formats.
Master model-driven FEA, CFD, EM solutions
With ever-shortening product design cycles, the emphasis on simulation tools to provide timely results is greater than ever. This pressure dictates FEA, CFD and EM analysis being driven off the master model CAD data. While CAD provides the geometry, a great deal of time is still spent preparing it for analysis.
CADfix for Geometric Exchange is uniquely positioned in the CAD-to-CAE data flow with its ability to read and write multiple geometric formats, repair and heal poor quality geometry and de-feature and simplify complex geometric definition. This results in more robust geometric definitions for analytical needs.

Advanced geometry processing
The powerful and extensible CADfix framework facilitates the development of advanced geometry processing tools to meet the demands of today’s leading engineering enterprises. Examples include the automatic morphing of CAD models to match analysis results, and the reverse engineering of faceted models into usable CAD geometry.
CADfix uses CAE analysis results on a deformed mesh and applies them to morph the original CAD model geometry. CADfix accurately morphs the original CAD surfaces to generate smooth, well-defined surface geometry that can be exported back to CAD as a usable model, or to CAE systems for re-meshing and further analysis.
Reverse engineering of faceted models
CADfix can import a faceted model representation, e.g. JT, STL, 3D PDF, CATIA V5 CGR or CATIA V4 SOLM, and reverse engineer this to a general CAD BREP defined by NURBS and analytic surface geometry. CADfix automatically splits the imported faceting into regular regions of triangles and creates new BREP CAD geometry and topology from these regions. Full automation is possible where the original faceted model contains predefined facet groupings or when clear detectable feature lines exist in the faceted model. The reverse engineered BREP geometry can be exported to CAD as a usable model for design purposes, or to CAE systems for meshing and analysis.
CADfix helps manufacturers prepare 3D CAD models for different downstream applications and minimizes expensive CAD model re-work. CADfix tools for Additive Manufacturing and 3D Printing include high accuracy slice generation with intelligent compensation for different manufacturing processes, comparison of manufactured part scan data to the source CAD model, and component placement tools for Build Box optimization.
CADfix ensures that your products are manufactured with the highest quality and efficiency that your manufacturing processes can deliver.
CADfix additive manufacturing and 3D printing features
CADfix geometry processing and model preparation utilities for Additive Manufacturing and 3D Printing include:
- Import, repair and preparation of 3D CAD model geometry
- CAD model feature removal tools to improve manufacturing process efficiency
- Manufacturability checks to ensure that the product can be produced
- Generation of good quality watertight STL files
- Model orientation tools to maximize Build Box density and manufactured part quality
- Automatic generation of 2D slices with intelligent compensation for different AM processes
- Highly accurate 2D slices for a superior manufactured part finish

CADfix for process plant
CADfix is used for the automated simplification of large complex CAD assemblies before import into Process Plant software applications. The goal of this simplification is to leave enough detail to accurately represent the model structure, while removing unwanted intricate detail to reduce file size more than 90%.
Simplification of equipment installations for process plant applications
CADfix simplification tools can be run in an automated batch process or with manual user interaction. General operations can be run in the automated environment, whereas manual interaction is normally required when the user must control the layout. Typical operations include:
- Filter and remove small parts based on bounding box size
- Filter and remove internal detail
- Simplify complex parts to minimum volume bounding boxes or cylinders
- Remove holes, protrusions and internal cavities
- Remove design features such as fillets, rounds and chamfers
- Join faces or bodies
- Delete user-selected entities
- Convert geometry to simplified lightweight forms
