Installation and first drawing

Install Ichno from Blender, then click Make Plan: the PDF opens on its own.

Install

1. Edit ‣ Preferences ‣ Get Extensions, search for Ichno, click Install.
2. Requires Blender 4.3 or newer (tested on 4.3, 4.5, 5.0 and 5.2), on Windows, macOS and Linux.

Your first drawing

1. 3D Viewport ‣ Sidebar (N key) ‣ Ichno tab.
2. Objects: Visible (everything shown in the viewport), Selected, or one Collection.
3. Click Make Plan. A progress bar shows each step; Cancel stops it at any time.
4. The PDF opens when it is done. The folder button next to Make Plan opens the last drawing again.

The drawing is computed by a second Blender in the background, from a temporary copy of your file. Your scene is never modified and you can keep working while it runs. Save your .blend first: the default output folder //plan/ sits next to it.
