Base Flange

The SheetMetalBaseFlange node is the foundational flat plate of a sheet-metal body. It extrudes a closed 2D profile by thickness and tags the result as a sheet-metal wall, so subsequent flanges and bends can be added with full parametric identity (preserved through Unfold).

You configure the project-level defaults — thickness, bend_radius, k_factor — once via SheetMetalConfig and every node reads them.
