September 30, 2026
CADEXSOFT announces the release of Manufacturing Toolkit 2026.6 — a CAD SDK for developers building quoting and MaaS platforms, with DFM checks, native B-Rep, feature recognition, and web visualization.
Manufacturing Toolkit 2026.6 highlights:
- STEP AP242 export with assembly structure and PMI.
- Oriented 2D bounding box computation.
- External chamfers and improved pocket recognition in CNC machining.
- Improved forming feature recognition and unfolding in Sheet metal.
- PMI support to MTK Workbench and MTK Web.
Read more about the changes in our blog.
STEP AP242 export with assembly structure and PMI
Manufacturing Toolkit now supports STEP AP242 export, including B-Rep geometry, assembly structure, and both graphical and semantic Product and Manufacturing Information (PMI).
Oriented 2D bounding box computation
The MTK API now provides Geom::Box2d and Measurements::BoundingBox2d for computing oriented 2D bounding boxes.
The computation supports both Drawing::CurveSet and sets of Geom::Point2d points as input. Depending on the selected criterion, it can determine either the minimum-area or minimum-perimeter bounding box.
CNC machining: external chamfers and improved pocket recognition
CNC feature recognition has been extended with support for external chamfers and additional pocket geometries.
The new Machining_Chamfer feature enables external chamfer recognition in Milling and LatheMilling operations, with chamfer length available as a feature parameter.
Pocket recognition now handles more complex geometries, including L-shaped, C-shaped, and S-shaped pockets.
Sheet metal: improved forming feature recognition
Sheet metal processing has been improved for forming features in both Feature Recognition and Unfolding.
Feature Recognition now handles sequences of bends and flat faces more accurately, avoiding cases where they could be incorrectly recognized as forming features.
Unfolding has been improved for enclosed forming features with a closed boundary fully contained within the sheet and no internal holes, providing more reliable flat pattern results for these geometries.
MTK Workbench and Web updates
MTK Workbench now supports browsing the PMI hierarchy, visualizing graphical PMI components in 3D, and viewing element properties.
Additional Workbench updates include:
- DFM analysis workflows have been improved.
- Chamfer features are now supported in Workbench.
- Workbench interface has been updated.
MTK Web introduces a new PMI API for accessing saved views, graphical and semantic representations, and their associations with model elements and B-Rep shapes.
Other MTK Web updates include:
- File loading and shared APIs in MTK Web examples have been reworked.
- Material management APIs have been reworked to improve resource handling.
- Several visualization and resource management issues have also been fixed.
