From a single dimension,
to a set of connections.

Operations are centered around the model.
Every step, see what is being changed.

Editing the shank length on the 3D model highlights the affected geometry.

New Operating Method

3.2 Continues the Modeling Direction of the V3 Series,
Put Dimensions, Objects, and Feedback Back into the Same Work View

3.1From parameter definition to thread mesh
3.1 MJ Thread Parameter Input Interface
Enter geometric and mesh settings by parameter group
3.2Edit and observe on the model.
Direct 3D dimension editing in 3.2
Click on the dimension to get feedback at the corresponding geometric location.

Two generations of software interface; respectively, MJ parameter example and M12 direct editing example.

editing is more intuitiveDimensions and geometry correspond, input and errors are feedback at the operational location.

work is more coherentProject tree, connection list, and model selection work together, with common actions concentrated.

observation is clearerThe shape, mesh, cross-section, and quality shading each represent one side of the model.

3.2 uses native Python, Qt / PySide6, and OpenGL for the desktop application. An independent Python Thread Kernel handles modeling. The software colors elements by scaled Jacobian, a mesh quality metric. The browser's 3D view displays previously generated project data. Mesh computation runs outside the browser.

Along familiar directions,
proceed forward

3.2 is an iteration of the V3 series.
TD Forge is the next generation of the complete connection engineering.
