• 3D_Kernel_iO

    CAD Interface Libraries Make all current formats available in your Software

CAD Translator SDK

Embedding our API makes 24 CAD formats available in your application - cost efficient and within the shortest space of time. Deploying 3D_Kernel_IO software developers benefit from the entire expertise and experience of the leading CAD interoperability experts.

3D_Kernel_IO's precise, reliable and fast Interfaces handle assembly structures, attributes like names, and layers as well as all entities like points, curves , B-REP Solids, Skins and also tessellated models. Furthermore, Features and the history-tree, PMI, attributes and metadata are directly accessible.


3D_Kernel_IO also provides our unique Advanced Healing Technology to assure perfect model quality. During the conversion process, the 3D Models can be adapted to the tolerance and the mathematics of the target system to provide exceptional quality. If activated, the Healing Functions will automatically correct failures, such as gaps, overlaps, twisted and mini-faces.

In addition the API offers many interesting functionalities that have been developed to satisfy all the specific needs of our customers developing leading CAD, CAM, FEA, Virtual Reality and Metrology Softwareproducts.

CAD Interoperability API

Embedding our API – makes all current CAD formats available in your application – Cost and time efficient. Today engineering software companies and their customers are looking for new ways to read a variety of 3D CAD data formats. 3D_Kernel_IO is the leading API with native readers based on the C ++ programming language. Allowing efficient, precise and independent access to all native and standard formats.


In addition 3D_Kernel_IO provides unique and proven functions and modules with automatic healing, PDQ-Checker, Assembly Manage-ment, Precision Tessellation and Model Comparision to expand the capabilities of your software.



Native Interfaces

All standard and native interfaces are developed and maintained by CoreTechnologie ensuring a guaran-teed support of the newest CAD format versions. 3D_Kernel_IO reads assembly structure, attributes like names, curves, or layers; entities like points, B-Rep solids and skins as well as tessellated models. Furthermore, features with history, PMI, attributes and metadata (e.g. DC Master, publications) are directly accessible without a CAD license or application. Supported Formats:


• NX™ • CATIA® • Creo® • SOLIDWORKS®

• ProE®/Wildfire • Inventor® • IDEAS™

• JT-Format • XT-Format • STEP AP 203/214/242



• and many more.....


During the conversion process, 3D models are adapted to the tolerance and mathematics of the target system to provide exceptional quality. Healing functions will automatically correct failures – such as gaps, overlaps – twisted and mini-faces. Even a set of single surfaces can be sewn together automatically into watertight solids with user-defined accuracy.

Easy to Intergrate

Available on Windows, Linux, Mac and ARM Platforms. The interrogation functions are standardized for all formats. Therefore, 3D_Kernel_IO can be embedded very easily and rapidly available in your application.

3D_Kernel_IO also includes a simple sample application, easy to use and useful to verify the results of your integration and test various options and commands that the API offers. It also comes with complete documentation as well as descriptive programming samples.

PMI Information

3D_Kernel_IO native interfaces also reads PMI information like dimensions, tolerances, annotations, datum’s and text. All links to the geometry provided; is mandatory to use PMI in Metrology and CAM applications. Generalized interrogation functions allow easy access to PMI data of any CAD format providing important information for a seamless PLM process.

Special functions

Providing specific functionalities for CAD, CAM, CAE, VR and Metrology. 3D_Kernel_IO is worldwide the unique tool for history and features. The extraordinary tool maps the construction history and parameters directly from the binary file without requiring access to a license of the source CAD system. Additional 3D_Kernel_IO native interfaces read featured information and PMI of threads, holes, chamfers, filets, patterns, drafts, pockets, extrusions, other feature types as well as assembly features. The data structure represents all feature types used by today ́s CAD systems.


The associated faces of each feature on the B-Rep model will be indicated by 3D_Kernel_IO and can be traced easily. Threads information is provided, which is important for annota-tions and PMI that reference construction elements like sketches, planes or datum axes.




3D_Kernel_IO can find geometric differences between two objects. The Kernel conveniently allows for comparison of objects to part solid, body or face; while setting minimum distance detected. The parameters can be set for the comparison of distance of minimum and maximum color variance by the type of part solid, body or face.


The accurate and fast tessellation of 3D models as well as healing functions for triangulated models opti-mize CAD data for digital mock-up, virtual reality and high-end rendering. Parameters for maximum chord deviation, triangle size, and the angle between adja-cent triangles are used for B-Reps or the recalculation of triangulated models. VRML, JT and STL are available.

Flexible Licensing

3D_Kernel_IO allows software editors to satisfy all their interoperability needs, dealing with only one vendor, one API and one predictable and affordable annual licensing fee or per license cost. The licensing system can be adopted as an open library with code protection, or optional locked API based on Code License service.
