octodraw
A downloadable CAD modeler
OctoDraw 3D is a fast, tool-driven 3D modeler for direct construction and editing.
100% private - your models stay on your computer storage.
Highly portable : android, windows,linux or mac desktops same file format.
Sketch with lines and faces, use precise snapping, dimensions, and transform tools, then build higher-level elements like walls, slabs, stairs, frames, voxels, and HVAC runs.
Dynamic User defined Objects will help you implement many advanced features by yourself without programming knowledge.
Extensible through plugins you can adapt it to your workflow ( exporters, custom tools ).
Includes vector text, object prototypes with hotspots, and practical import/export workflows. On Android, external mouse + keyboard are strongly recommended for best control.
at base being a java application it can be run on any OS java 21 will run.

the app is available on snap store https://snapcraft.io/octodraw
the app has also a dev console thats a bit similar with the chrome dev console, you can expore the model, launch commands, move the camera or draw geometry in a way that is reminescent of autocad ( there are some command aliases but at its root it is a groovy console that 'sees' the object model.
on Windows the console is a bit quirky : you need to press enter after launch if you want to see the TUI above.
the android app supports touch handling of the camera, the feature is quite new and still need to undergo more UX testing ( though as it is right now it is imo quite good ).
the documentation is really lagging albeit the basic tools and handling have not changed even though the UI structure is organised different.
