Arrant Engineering

Senior SolidWorks Designer + CAD API Developer.

For 14 years, I have engineered sheet metal, weldments, enclosures, and large assemblies in SolidWorks. When the same repetitive CAD work kept slowing every project down, I started writing the C# add-ins and macros to skip it. Today I do both — I design products that ship, and I build the SolidWorks API tools that help other CAD teams ship faster.

Two ways I help engineering teams ship.

Mechanical Design

For hardware founders, product teams, and engineering managers who need production-ready CAD.

  • — Sheet metal, weldments, and IP-rated enclosures
  • — Large SolidWorks assemblies (proven on 8,759 components)
  • — ASME Y14.5 GD&T manufacturing drawings
  • — Design for Manufacturing (DFM) reviews and 2D-to-3D conversions

SolidWorks Automation

For CAD managers and design teams losing hours to repetitive modeling, file management, and drawing tasks.

  • — Custom SolidWorks add-ins (C# / SolidWorks API)
  • — VBA macros for repetitive workflows
  • — Batch processing — drawings, PDFs, DXFs, BOMs
  • — Pack-and-Go automation and EPDM workflow tools

How projects run.

  1. 1

    Brief Review

    Send sketches, files, or workflow notes. I review scope and flag risks early.

  2. 2

    Scope + NDA

    I work under NDA before detailed files are shared. Clear deliverables, clear revision boundaries.

  3. 3

    Build

    Direct communication with the engineer doing the work. Structured checkpoints, no handoff chains.

  4. 4

    Delivery

    SolidWorks files, STEP/IGES, DXF, BOMs, drawings, or packaged add-ins — ready for fabrication or rollout.
