"2d construction drawings are usually enough to reason about your mechanical problems and I wish there was an open source software that would augment the worklflow based on a pencil-and-paper metaphor." Last year I was looking for something with the same use case in mind. Quick 2D drawings, with modular blocks, and preferably open source. The closest thing I found is qcad [1]. It has a lot to offer, but not everything is intuitive. So for me it was necessary to do a few of the tutorials. There is also LibreCad [2]. A fork of qcad, which looks more modern (I did not try this one). Still I did not yet find something that "augment the workflow" of the pencil and paper metaphor for mechanical applications. This would be really cool. Maybe even something compatible with the newest eInk devices. [1] https://qcad.org/en/ https://qcad.org/en/ [2] https://librecad.org https://librecad.org
