Kubotek3D releases version 4.0 of K-Display and K-Compare products

Improved software with updated CAD file readers, additional support for mesh objects, and improved large assembly visualization capabilities

MARLBOROUGH, Mass. – April 7, 2022 – Kubotek3D, a leading supply chain software provider, today announced version 4.0 of Kubotek K-Compare and K-Display software products. This major release provides CAD file reader updates, user interface improvements, and several new features for each product. New versions can be downloaded immediately by customers.

Updated CAD readers

To ensure that customers are prepared for all CAD files sent to them, the playback of 3D CAD files in all Kubotek 4.0 software programs has been updated to support new versions of ten file formats CAD:

• Autodesk Inventor 2022

• Dassault Systemes (DS) CATIA V5 R2021x (R31)

• DS V6/3DExperience R2021x

• DS Solid Works 2022

• DS Spatial ACIS 2022

• PTC Creo 8.0

• Software Siemens Digital Industries (SDIS) NX 2000 (1980 series)

• SDIS Solid Edge 2022

• SDIS Parasolid V34

• SDIS/ISO JT 10.7

Support for the Solid Edge .psm sheet metal part format has also been added to all K-Compare and K-Display products. Kubotek KeyCreator support in K-Compare products has been updated to CKD 2022 file format.

Major K-Compare improvements

Kubotek’s K-Compare Revision and Validate products enable absolute clarity in engineering changes and moving 3D data with confidence. Both products are able to quickly read the structure of large CAD assemblies from all major CAD applications. With version 4.0, K-Compare products now offer users the ability to open/view selected parts from the assembly parts list.

Version 4.0 of K-Compare Validate adds support for several types of 3D data requested by customers. The first data type added is the stereolithography (STL) mesh commonly used in 3D printing and additive manufacturing. With the Premium tier of version 4.0, STL files can now be compared to the CAD file they approximate. K-Compare Validate will alert users if the STL file deviates from the original within a user-defined accuracy and records that this verification has been performed for quality compliance requirements. The second type of data with additional support is Product Manufacturing Information (PMI), such as tolerancing attached to faces in STEP AP242 models. K-Compare Validate 4.0 provides a complete semantic comparison of STEP AP242 PMI to confirm that these annotations have been correctly transferred from the original CAD file. The last new data type supported for comparison is 3D wireframe entities stored in the KeyCreator CKD format.

Major K-Display improvements

K-Display View and Convert are easy-to-use cross-platform applications that allow anyone to open almost any CAD file and repost models in standard formats. Version 4.0 adds the ability for users to review properties such as volume and center of gravity of lightweight 3D objects saved as mesh entities (sometimes referred to as tessellated or triangle/polygon 3D models or shells). File formats that these meshes can be read from include STL, CGR, 3DXML, STEP, and KFW. This functionality works similarly to examining the properties of specific 3D objects saved as solid entities. In either case, this information can be useful in estimating the quantity or weight of materials for cost estimating or process planning.

A new ability to move and/or rotate objects relative to each other has been introduced. Moving objects away from each other allows users to better visualize a complex assembly where certain part and sub-assembly locations in the original CAD assembly file obstruct the view of other parts.

The ability to export files to a 3D PDF file was also added to K-Display products in version 4.0. 3D PDF files allow K-Display users to share 3D information with others who do not have CAD viewer software installed. The exported PDF includes a Universal Compressed Mesh (U3D) 3D model, including 3D annotations. Browser software such as Google Chrome will display a shaded static version of the 3D model and annotations. Standard PDF viewing software such as Adobe Acrobat DC enables 3D data to be activated and manipulated with extensive viewing and navigation capabilities.

A new ability to discover assembly structure allows users to quickly improve understanding of a complex set of parts saved in a single file by automatically sorting identical sets of solid entities into a single reference entity linked to each location. This feature saves time and avoids potential errors when determining component counts on large assemblies.

Free trials of Kubotek software are available. Kubotek3D is also looking for referral partners and qualified resellers for these products. For more information, visit kubotek3d.com.
