24/09/2026

✅ Now available: Manufacturing Toolkit 2026.6 💡The new version introduces STEP AP242 export, improved CNC and sheet metal feature recognition, and extended PMI support.

🚀 Highlights:
• Added STEP AP242 export, including assembly structure and Product and Manufacturing Information (PMI).
• Added oriented 2D bounding box computation with minimum-area or minimum-perimeter criteria.
• Added external chamfer recognition and improved recognition of complex and round pockets in CNC Machining.
• Improved forming feature recognition and unfolding in Sheet Metal.
• Added PMI support to MTK Workbench and MTK Web.

✅ Empower your software to generate flattened representations of sheet metal parts with MTK.

In some scenarios it can be useful to unfold a sheet metal part to get the original flat metal sheet which was used to produce this part, for example:
• computation the dimensions and perimeter of the original metal sheet;
• association of the current shapes of the sheet metal part with the original flat metal sheet ones;
• transferring the result to CAD systems to design documentation.

✅ Designing parts for CNC machining? Even seemingly simple drilling design elements can introduce manufacturability challenges.

Here are some common Drilling DFM issues to watch out for:

• Small Hole Diameter
• Deep Hole
• Flat Bottom Hole
• Non Standard Hole
• Non Standard Drill Point Angle
• Non Perpendicular Hole
• Intersecting Cavity Hole
• Partial Hole
• Small Distance Between Threaded Hole And Edge

✅ Read and manage semantic dimensions, tolerances, and notes embedded in CAD data with MTK.

The Manufacturing Toolkit implements a comprehensive data model for PMI, allowing developers to query, modify, and integrate it seamlessly in C++, C #, Python, and Java.

✅ C # examples migrated to .NET 8 in MTK 2026.5

All MTK C # examples have been migrated to .NET 8, replacing the previous .NET Framework 4.6.1 and .NET 7 target configurations.

The CMake-based build workflow has also been removed. C # examples now use only MTK libraries targeting .NET Standard 2.0, simplifying their build configuration.

✅ Reworked Visual Measurements API in MTK Web

The MTK Web Visual Measurements API has been reworked to make measurement workflows more flexible and extensible.

Measurements are now created from neutral measurement targets that can work with any data model source. Custom measurement types can be declared, registered, and used alongside built-in types without modifying the feature code, while measurement creation and replacement are now fully typed.

All interactive measurement capabilities also have corresponding options and API methods, allowing the same operations to be controlled programmatically.

✅ Markup Creating Viewer example in MTK Web

MTK Web examples now include a new Markup Creating Viewer that demonstrates how to build model review, annotation, and collaboration workflows into web applications.

The example supports model upload, review mode switching, object highlighting, and creating, editing, and filtering notes. You can also create pins in the 3D scene, attach them to model entities under the cursor, and add custom text.

✅ CNC machining: improved hole depth calculation in MTK 2026.5

CNC feature recognition now provides more accurate depth values for holes with complex or interrupted geometry.

For stepped holes, depth calculation has been improved for cases where sub-features overlap, such as a countersink combined with a threaded hole whose threaded portion extends into the countersink.

Depth calculation is also more accurate for holes interrupted by intersecting geometry. In these cases, a single hole may be represented by multiple separated coaxial cylindrical faces, which are now handled more reliably when determining the overall hole depth.

The updated calculation uses the overall geometry extent along the hole axis, providing more accurate results for both overlapping stepped-hole sub-features and interrupted holes.

🚀 Sheet metal unfolding is now available as an independent process mode in MTK Workbench instead of being part of the feature recognition workflow.

The new Unfolding mode includes a dedicated Flat Pattern structure tree and displays key dimensions, including width, height, thickness, and perimeter.

✅ Improved bend and detailed edge geometry processing for sheet metal in MTK 2026.5.

Sheet metal processing now handles detailed edge geometry more reliably. Improved geometry recognition and thickness detection provide better support for parts with fillets, chamfers, beveled cuts, and other features that alter otherwise simple sheet metal geometry. This makes processing more robust across a wider range of real-world sheet metal designs.

Bend recognition has been improved for models with a zero inner bend radius. In these cases, the inner cylindrical surface is absent, leaving a sharp edge while the outer bend surface remains curved. These bends are now recognized more reliably, improving support for a wider range of sheet metal model representations.

Bend length calculation issues have also been fixed in Unfolding. The updated implementation improves bend allowance calculation and K-factor handling, providing more consistent and accurate bend width and length computation across a wider range of sheet metal models.
