Good evening, everyone. I'm a mechanical engineering student and I'm practicing technical drawing. can I kindly ask you an opinion on this design? I had to extract the particular n°1 from that together. Thanks to who will answer me!

The wrong design. errors are always the same starting from the unreadability of the design.

instead of starting new designs wouldn't you want to finish those already started?

If you want to learn, study well on the drawing book.
However, in our times that we could not ask about the forum that looked at the drawings, we modeled with a cad and we made the table and tried to figure out what was missing and why comparing with the explanations of the book.

brown on brown you see very well... .
there is flash and a minimum of photo correction to make readable.....bah

I have two technical drawing books, but unfortunately I see that beyond the norms and exercises, there are no solutions or at least the drawings in assonometry in order to be able to control. for this I will treasure your advice and learn to use a cad to compare and understand if the "third view" is correct.

still wrong. start learning the use of lines (visible, hidden, axles, etc.) otherwise you will never make a correct design.
I have already said that the forum is full of commented drawings that you can study and try to remake, material to study the projections, the use of the lines, norms and anything else, also I have reported to you resources from which to start drawings and compare them with the solution.

I take advantage of it to ask you, what is a cad that I can download for free from which to learn and of which there is perhaps a course on youtube that I can follow?

Hi.
first a question, these drawings of assemblies, from which to extrapolate the components, choose you, or are exercises given by the professor?
This is because, if they are exercises chosen by you, I would try to change approach by taking a step back. .
begins to take a design of a particular simple single, seen in assonometry, and project it on the floors,
and away always with more complex details.
so begin to get used to the mind to create a connection between flat object and 3d view and then shape objects.
In my opinion, this system allows you, when you look at an axial section, to extract mentally in 3d the component and then to be able to reproduce it.

Thank you very much for the advice. No, these are exercises that I am taking for practice, as the exam will ask to extract a particular. In the meantime, I'm also doing exercises like that. in the meantime I send you the design I tried to correct. I tried to remake the view from above, although from that view you should not see the holes

and what do you do when an entity is not visible? draws in hidden line.
You're almost there, scattered notes:
- insert section line
-The plant lacks hidden entities
- in the right view there are hidden entities
-no axes
please improve image quality because you struggle to read it to monitor, figure on a mobile phone; not all have 20 years and 10/10 of view

Estrazione particolare da complessivo
Se provi a disegnarlo in assonometria (vista 3D), uno schizzo a mano senza misure o proporzioni corrette, di come te lo immagini, magari ti può aiutare..
with these you do your design, then compare it and do an autoanalysis of your work on which I recommend you write to yourself what were the errors so as to check not to give it back to the next exercise.

Thank you very much. for the hidden lines, the prof always stated that it was better to dissect , for this I tended not to make them ( but in this case dissecting I would not have seen other details, but I could have seen the holes for example) . I understand the advice of doing the adenometer, but my problem is to imagine the piece in 3d , for this I am doing other exercises as suggested by another user. I will now make the drawings you propose.

You don't understand. Absonometry is contained in the drawings, you don't have to do it.

in all the drawings that I am doing there are only the views in 2d, there is never the piece in 3d close, otherwise I would have solved many problems already. I should imagine seeing the view, but that's where I have the greatest difficulties

in the link I had already given you a couple of weeks ago there are also the assonometries and I had already written it! ! ! ! ! ! ! !

in these drawings are there and I have seen. Unfortunately, there will be no examination. I meant that. Now a question arises spontaneously, is it necessary that I make the view from above? in the previous design for example, could I quote in the view in the plant and the one from the right and end there?
