## Summary

- KetchUp is a free app for drawing 3D models with exact dimensions before building furniture such as shelves, tables, cabinets and workbenches. It is described as usable without an account.
- You draw board outlines with rectangles and lines, pull up faces to give them thickness, and enter lengths directly or add dimension marks to check the assembled shape and proportions.
- Installers are available for Windows (x64), Mac (Apple silicon) and Linux (x64). It also opens in desktop browsers that support WebGPU or WebGL2. It is said to be released under the MIT license and written in Rust.
- Work is saved automatically in that device's browser and can be downloaded as a .ketchup file. It can also import SketchUp (.skp) geometry and export OBJ files.

  O: The author suggests that anyone planning to build a shelf at home give the rectangles thickness and enter the real dimensions to check how the assembly will look before cutting any boards.
  X: Browser autosave stays only on that device and can disappear if you clear your browser data, so work you want to keep should be downloaded as a .ketchup file.
