extraction of a particular from together

[andream12]

Hello everyone, I am a student at the first year of vehicle engineering in modena, and I will have to give the industrial technical drawing exam. are at the very first weapons with this matter, never having practiced it until 2 months ago. In particular, I have a lot of trouble interpreting how the piece is done starting from drawing together. In this exercise I was asked to extract piece n1 from the axieme. I attach to you what I have tried to do and I ask you the kindness to report to me any kind of error, (I know there will be many) , ideas, ideas and observations to try to gear in this matter. Thank you in advance to those who want to help me.

to me comes the headache to see the rotated drawing of 90°.
please put it turned correctly and if possible from a bit of contrast so that you can read well without straining the view

However ask yourself how those m10 screws do (pos. 10/n) to stay stuck if you made a 20mm central socket. eye projections are also wrong.

who arrives at university and has never seen the technical design, which is the alphabet of the mechanic, must by force of core try to make repetitions and take to step with the course of studies.
I suggest you take drawing books from the superiors and do those exercises. You will see that one step at a time you will begin to understand and learn the rules of technical design.
on the forum we have also arranged online material.
It is important above all if a tomorrow you will make the designer... .

I tried to take the picture better, at least in vertical position. what is difficult to me is to understand how to represent the piece in the view from above, that is how this base is made in the part we say "central", starting from the section a-a

I own the two volumes chirone backincasa and there are exercises, the only problem is that there are no solutions, so I would have no way to check if they are right. Moreover it is the same book from where the prof takes his exercises. If you had any material with the possibility of verification, I would be very grateful.

I reload it more readable

 

[MassiVonWeizen]

as I had guessed the projection lines are completely wrong, then as you did to get the b-b section, which is not at all a section, but the copy that is in the original design, without making traces is a mystery.

you always start from the bases, so learn first of all to make the correct geometries, then you will be a little easier to read the drawings.

 

[andream12]

Thank you very much, the b-b section I got it from the a-a section to try to show the different heights. I hope I haven't made any more big mistakes besides projecting the lines, although I realize that it is already very serious.

 

[andream12]

I tried to represent that "rizo" that you see from section to -a in the view from above, is there that I found myself in difficulty

 

[MassiVonWeizen]

other error for one who has just started and position the view of a section on the opposite side to the cutting direction; you cut up and position the view down. It is not a technical error, because if necessary the views can be put, with good sense, wherever so there is the arrow to indicate the direction of reading, the error is logistic because you who can not read a design you are complicating your life and instead of analyzing the exercise you have limited to copy what you saw by placing the views where it happened.
If with a compass I tried to track the projections maybe you could understand how the object is made, what is that rise of which the silhouette is seen in the view in the plant (left under the knob)

do this: take a colored or similar pencil and track all the contours of the object, then, as the particular has two heights, with two other colors highlight the lower part and the upper part.

how the piece is done in itself I think I have imagined it, it is difficult to represent it with the right lines and in the right position in the view from above. And I think that's a very basic thing, I remember in the middle school and I repeat only in the middle school, they made me project the lines on one of the planes, maybe something now comes back, and that's where I'm wrong. but these things rightly in class have been given for granted.

It seems to me that the piece is not quite clear to you.
in addition to the suggestions of massivonweizen, I would tell you to remake the a-a section from your view from above and without seeing the original.

However ask yourself how those m10 screws do (pos. 10/n) to stay stuck if you made a 20mm central socket. eye projections are also wrong.

I don't know how you got the central oval shape. If you look at the axieme plant view, you will see that, on the side of the flyer, you see the rows of the central rise. then that rise is passing through the whole piece and acts as a guide for support 3 (which in turn will have a channel that will welcome that rise). then there will be a single central slot for the vines.

a clarification: in the annexed table No 1, naming: base,
the overall design is mistakenly called, in the first line of text: (against).
it is necessary to highlight that it is the total of counterhead of a lathe; the counterpoint is the detail n. 8 referred to in the drawing and the relative table.
