New mesh generation class, threaded hole feature, and improved unfolding algorithm in Manufacturing Toolkit 2025.4
Generate meshes for all shapes or selectively, try a new threaded hole feature for CNC machining and evaluate more accurate unfolding of complex sheet metal geometries.

Here are the highlights:
- New ModelAlgo::MeshGenerator class for advanced mesh creation;
- Added CNC machining feature: Machining_ThreadedHole for simplified thread design;
- Improved sheet metal unfolding for B-spline surfaces and shell-based models.
New mesh generation class
We are excited to introduce mesh generation through a newly implemented algorithm. The ModelAlgo::MeshGenerator class enables generation of triangulations for B-Rep shapes with user-defined granularity. You can now generate meshes for all shapes or selectively for those lacking existing triangulation. The generated mesh can be useful for basic computations or if you want to visualize it on your side.
New threaded hole feature for CNC machining
From this release, list of features for CNC machining has been enhanced with one more to represent holes produced by threading operations. The Machining_ThreadedHole feature has the following parameters: minor and major radius, pitch, thread length, and depth and supports three variations—through hole, blind hole, and flat bottom hole.
Improved sheet metal unfolding
The Unfolder now delivers higher precision for B-spline surfaces, ensuring more accurate unfolding of complex sheet metal geometries. Additionally, we have resolved issues with shell-based models, eliminating incorrect unfolding behavior.
Web enhancements
Web examples have been completely refactored with a cleaner folder structure and architecture—shared functionality is organized into reusable components and classes. Additionally, you can now try a new molding process in MTK Explorer example, demonstrating manufacturing workflows in web applications.
