How to design and construct a complex product?

Question

Do it yourself

Recently, in the backyard of consciousness, the thought flashes of how to make yourself a comfortable workplace for programming. I would like not just to pick up and buy a table with a chair, but to create it myself.
There are some interesting photos on the Internet:

It would be interesting to work through the whole cycle. Starting from the design of the chair and monitor holder, ending with the keyboard.
The algorithm looks like this:

1. Come up with
   
2. Design in drawing
   
3. Turn the drawing into reality with the help of machines
   

The problem is that I don't know anything about the last two points. What software to design? What machines are needed? Is there a place in Moscow where you can come with a drawing and work with a tool?
In general, whoever has a similar experience or who does it professionally, please share. A couple of tips, links, what tools you use and all that.

Answer 1

scetchup, kompas, nanocad, autocad, solidworks, catia - there are many CAD systems and they all represent different possibilities. Choose according to what you do and how you do it. For example, catia (not only it) is used in the aircraft industry and allows you to simulate and build CNC programs for various technological processes (milling, stamping, turning, casting, bending, etc.) scetchup cannot do this, but it is incredibly easy to learn.
It’s probably worth starting with a sketch in paint or on paper, deciding on materials and possible methods for processing them, then choosing a system, solid work is probably the golden mean, get a model in it, cut off everything superfluous, recycle something - for example, if you need plastic of a complex shape, and you understand that casting is not financially feasible, or change the model or choose other technologies (3D printer, milling). At the same stage, you will find out and calculate all the costs and their order (you need to order a bearing from China - we order in advance, because it will take a long time, and after turning it would be better to check the part immediately; choose several possible performers for each of the processes)
The design is finished - let's get down to implementation - here you yourself google what, where and when. If vkrtace, then in Moscow there are several carpentry workshops where you can come and for denyuzhka or order a part or make it yourself. Find lathes, cnc machines, etc. it won’t be difficult for metal processing either, although most likely no one will let you in without preparation, so the execution here should rather be delegated to the craftsmen. Plastic molding is expensive, time-consuming and unprofitable for small-scale production. But the manufacture of plastic parts and products using additive technologies is a feasible task. You can even stumble on a 3D printer now, so you will find it yourself. Ordering glass parts is also not a problem, you can find those who cut and those who blow. Leather, fabrics - appropriate ateliers. There are also exchanges of performers, such asthis one . In general, decide on the project, if there is finance, it is not a problem to implement it. And it will cost much more than standard ones. Keep it up and keep us posted.

Answer 2

any CAD programs, solidvorsk for example.
Not the most difficult things you can try to do in fab labs
