ThreadMeister – Heat-set Insert Creator for Fusion 360
Copyright (c) 2026 Andreas Kircher

SPDX-License-Identifier: MIT

This add-in automates the creation of heat-set insert holes for 3D printing,
using the dimensional specifications from CNC Kitchen.

Author: Andreas Kircher (Andreas.O.Kircher@gmail.com)
Created with assistance from: Claude (Anthropic) / Perplexity
Insert specifications from: CNC Kitchen (cnckitchen.com)
Version: 1.2.5

Features:
- Creates heat-set insert holes at sketch points
- Hole creation with CNC Kitchen specifications (M2-M10, 1/4"-20) – customizable via config.ini
- Blind holes and through holes
- Automatic chamfer for easier insert installation
- Automatic bottom radius for blind holes
- Timeline grouping for easy management
- Direct subtraction from target body
- Clean temp sketch approach for reliable profile selection

Usage:
1. Create a sketch with points where you want insert holes
2. Click "ThreadMeister" button in SOLID > MODIFY menu
3. Select target body and sketch points
4. Choose insert size and options
5. Done!

Known Issues:
- Not tested with Apple macOS
- Overlapping bores may cause incomplete extrusions (no chamfer/radius)
