MetalWB is a workbench for creation of welded frames and structures.
It uses profiles mapped onto sketchs as a base, and handles cut, trim, operations.

This repo and source code is heavily (like, really) based on the work of this repo: The work was done by Veloma and Jonathan Wiedemann.
In its final version, it should allow to cover the whole welding design workflow :
1) Skeleton creation with sketch lines or geometrical primitives; 2) Application of a profile on the skeleton, to create a part; 3) Adjustment functions (e.g. removal of overlaps) or addition of specific elements (gusset, weld bead, etc.); 4) Export of a spreadsheet that lists each part of the assembly, identifies the profiles and their length.
