No doubt there are already quite a few explanations everywhere, but too much does not allow us to choose anymore.
I never worked, 20-30 years ago, with a CAD program for architectural plans.
Today, I need to draw projects again, so I would like to try my hand at the Draftsight program. (I also worked a few hours with Solid Edge 2D)
This seems easy enough, except perhaps for the choice of hatching, which is quite different in the 1:1 scale worksheet than in the scales for paper outputs.
But I'm afraid of getting confused quickly with the line thicknesses, the adjustment of the slaps, ... In short, to start in a clumsy way .
where could I find a guide "to get started with the drawing of an architectural project in 2D CAD"
http://abouthouses.eu/fr/node/478: this is a small reminder pad for functions.
http://fr.tuto.com/draftsight/draftsight-fondamentaux-et-creation-plan-architectural-draftsight,33948.html: it's a paid video tutorial, of course, but it includes an arch plan from A to Z.
I think that by following it to the letter, it can be extremely interesting because it summarizes all the "key" functions in this field.
But I see that you offer me documents related to industrial design in general, or to the design of the building. On that side, I'm quite served. I worked for nearly 20 years as an architect, drawing plans, facades, technical details, .... on paper, with my little rotrings
What questions me more with a CAD program is to start well with the layers, to handle the line colors of the sheets rather than the line thicknesses, to solve the hatching problems, ... and probably many other things that you probably need to know better when you start rather than having to rework everything when a project is already well advanced.
In fact you need a basic tutorial on how to use layers, strokes and other features of a software, knowing that on this point all software is equal (or is close).
In this case, I advise you to watch some video tutorials, and skip if this is something you already master, example of research:
Or here's a quick tutorial (which is not on the same subject, I concede) that seems to answer your question about layers and line weights, i.e. how to manage the basic tools:
