If you only need 2D, there is LibreCAD.

I think everyone's got the CAD/3D programs covered, so a slightly "out there" answer:

If you're just doing 2D blueprints for yourself, do you actually just need a 2D vector program for doing a scale drawing with measurements?

I've done a lot of floorplans / layouts/ site maps etc using Inkscape, for instance.

It depends on exactly what you're wanting out the other end - so you may be lacking a lot of the features in a full CAD program, but the learning curve is comparatively so shallow that you might have a working plan by the end of the day, rather than the end of the month.

It's not perfect, but for that stuff, I'd use SweetHome3D.

Onshape has a free tier, though all the cad files you make in it are publically available. That being said, it's easy to use and, since it's browser based, completely comparable with linux

Qcad is a good one for drawing blueprints

I never tried it, because it is 2d only: https://flathub.org/apps/io.github.dubstar_04.design

Sketchup 2022 works flawlessly. Arch

I’m in need of a CAD program with an easy aproach for someone with zero experience on this type of software.

If you have zero experience with CAD, but some experience with programming languages or things like LaTeX, JSON, XML, HTML, etc., I'd suggest giving OpenSCAD a try. While it is definitely for more advanced users, it managed to instantly click with me, in contrast to FreeCAD and others I just couldn't get into (or rather back into, since my AutoCAD lessons back in school >20 years ago). That it allowed me to work work on CAD drawings in Emacs helped too...

If you want to do accurate calculations, wall thickness, exact angles, window sizes etc., I would recommend FreeCAD, especially the draft workbench and possibly the BIM workbench if you want to go 3D afterwards.

If you are more looking for a rough planning where you can test furniture placements, floor designs and see fast results, I recommend The Sims 4 (no joke!). The base game is free (also available on Steam) and it's quite easy and intuitive to move stuff around, change a wall, place decorations etc.

So far I used SweetHome3D, Onshape and Qelectrotech (for electrical) for the renovation of my house.

However if you are planning to do some heavy renovations in your house I would advise you to get an architect to do a proper blueprint of your house and a blueprint of what your house would look like after renovation.

It's not necessary, it might feel like it's extra money up front that you don't use directly for renovation but in a big project you save so much in the long term. This is what we did and there is so many (expensive) mistakes that we avoided because we had an expert eye at the beginning of the project.

For what you are doing SketchUp might be the best tool. Its easy to work with and good with architectural stuff.

Look at QCad. They have a paid ($40), and a free version that is fully functional and open source. It's the most autocad-like app out there, so learning that has the advantage of learning the UI of autocad too.

LibreCad that others suggested was forked from Qcad about 15 years ago and hasn't moved much in terms of features. While QCad has. So in my opinion, it's the best solution.

Then there's Freecad, but that's more about 3D cad, and it's more complicated overall.

If it's 2D then use AutoCAD on the web.

I did something similar recently, old house, wanted floor plans for renovation / idea generation.

Initially I started with FreeCAD and used the BIM functionaly, worked well, but a few bugs at time.

I've done a few smaller scale models of some rooms recently in [Bonsai](https://bonsaibim.org/(formerly BlenderBIM), and found the process a little more pleasent. This could be due to my previous blender experience and the hotkeys being more on my bones.

I've been doing amazing stuff in FreeCAD. It has a lot of power that lets me do things I never thought I would be able to do. It's also riddled with bugs that will make you want to throw your computer out the window.

My success with FreeCAD comes from extremely strict version control and years of use. I've learned to live with a few specific bugs. For example, external geometry doesn't work and hasn't for 14 months. Don't believe the forum when they say it works. It does not. In any given sketch, you will be able to make is 0 or 1 external link work properly without breaking your drawing. If you have more than one external link, even if you aren't using any of them, it will give you a "wire not closed" error when trying to pad or pocket.

Oddly, the subshape binder works perfectly and it is the illegitimate brother of external links. It even uses the external link tool to define import links from the binder object. Using a master sketch and the subshape binder is absolutely brilliant and wildly productive.

It comes down to having several tools to do any given thing but only one or two may be working.

There is a decent architectural plug-in for FreeCAD. I think Yorik wrote it, some time ago, but it's brilliant. I've used it for doing exactly what you describe on several house projects and it's helped quite a bit with renovations.

SweetHome3d is also a decent app but extremely primative and it's not going to create professional looking blueprints for anyone. It's really just a toy but can be extremely useful for mocking up a design or room layout. I have used it for years with great benefit. It's simple, quite powerful, and a brilliant visualization tool.

Honestly, if you want to create real blueprints to give to a builder, you're going to need Windows or OSX and one of a handful of applications, preeminently AutoDesk REVIT. REVIT is probably over specified for your purpose but it's the adult table. At least, know it's there if you find linux apps have too many shortcomings.

As a professional 35 year draftsman, I would recommend you buy an 11x17 gridded notepad, a pencil, an eraser, and then make numerous sketches. Do an plan view of each floor to create the general arrangement and the room-to-room relationships. Sections will be required at each elevation to show heights. Then sketch each room on its own sheet. Here you can supply more detail, using matchlines, etc. In this manner, you don't have to bear the burden of drafting and accuracy until you are behind the screen. You can just sketch the idea, and provide the numerics. Sketches need not be pretty or to scale or made by someone with any drafting talent at all. Use placeholders. A square with 'TLT' in it is just fine for a toilet. Later, the sketches can be redrawn in cad via a scaled floorplan and your placeholders detailed as required. This is generally how I would proceed when I had to draw up large steel furnaces in which the OEM drawings were lost.

With that in mind, Id suggest paying cash to someone else that has cad software and knows it. This is not a large or even complex project. They can take your sketches and recreate them into a 2d drawing set assuming you did your sketches right. While it will be a great accuracy check, I recommend this just so you don't have to run CAD on Linux, an endeavor that is sure to cost you that cash in time and frustration alone. It's just not suited for the heavy throughputs of CAD.

Consider this. If your choice of tools does not matter, you could replace your screwdriver with a butter knife for this renovation. As well you could use a rock in place of a hammer or some eco-friendly hemp string in lieu of your tape measure. If the choice of operating system, the base for all software to run on, is a negligible detail you may as well remove your foundation while you are at it. It's just going to crack and leak in 200 years or so.

If you don't know any starving draftsman or doing it yourself is an additional goal, then at least go buy a cheapie beater windows laptop and get a mainstream cad software, even if it's free. You'll be needing something mainstream to get good search results as you learn to run it.

And please, if this comes off as rude, I assure you that it's borne from my first hand experience. CAD drafting is not difficult, but it is tricky. There will be many moments where things can get off the tracks without you realizing it. It's disheartening to say the least when you realize that many minutes, hours or days ago you punched a bad number, misread something, phone rang and you got distracted, etc. And then when that happens, you have to know how to fix it since some of the drawing is right and some is now wrong, and a wrong drawing isn't necessarily worth the paper it's printed on. A good cad guy will avoid most of these traps for you entirely.
