Cable List Maker from Schematics for Panel Shops

Cable and from-to lists out of DXF schematics, for small panel shops.

Panel shop drafters copy every cable ID from schematics into Excel by hand. This tool turns a DXF schematic into a from/to cable list.

The pain point it solves: CAD to Manufacturing Gap

Users struggle to convert CAD models, scans, and photos into clean, accurate, and manufacturable files for 3D printing, CNC, and casting.

Why those fall short

  • still slow; subassembly-only work causes misalignment rework
  • imported threaded parts still carry heavy helical geometry; suppression is manual
  • No time-based creep simulation setup; anisotropic print properties not modeled
  • tracking lost on shiny, black or low-feature parts; scans incomplete and inaccurate
  • unknown
