it's enough for me. the center will be equal to that of the cap so with a tastat is obtained automatically, at the most put it as an auxiliary quota.

Thanks for the answer.
I must represent in 2d the various views, possibly with some view in section. What angle should I quote? and where should I put it in? I can't tell you about the car. this piece is educational, so it should not be realized, even if it must be feasible!
I only care to represent it correctly according to the technical design rules.

but do you have the basics of technical design?
the axes of the holes intersect in a hypothetical center, which in theory is the same as the radius of the cap (in theory because for functional reasons it may also not be so). in which view would you draw these axes? if the axes intersect means that they are not parallel then form a...
concrete
b angle
c sandwich with scamorza
But if you had drawn the views and studied them, you wouldn't have asked such a question.

Obviously my question has not been understood.
Fortunately I am not permalous, but at this point I would like to tell you that I am a three-year mechanical engineer graduated with 110 and praise and that at the technical drawing examination I was rated with 30. I can't boast of being a technical design expert, but of course the basics I can say I have them.
I repeat trying to explain myself better.
the axes of the holes intersect in the center of the cap as you say and certainly are not comlanaries. right from here my question: where do I go to write the quota?? I don't understand what's difficult in my question. It's obvious I've got a corner. But where do I go to write? (e.g. if the axes were comlanaries I would make a view in section that contains the axes of the holes and there I would put the angular quota).
I hope to be explained and the invitation in case you could answer not to assume the preparation of others on the basis of his incomprehension of the questions or the confusion deriving from the hours near the meals (see the aforementioned sandwiches with scamorza coat also I with humor).

If you ask me what view you have to put angular quotas a doubt about the knowledge I allow myself to have it.
I read student, not mechanical engineer, which then a title says little.
I did not give a direct answer with all the steps, put a sketch, because reasoning and the best way to learn.
But since...
in the side view draws the axes
quote the angles between the axes and put the quotas at a suitable distance, to the scale of representation, from the spherical edge.
do a decomposed section on one of the holes (or do a detail) and quote the hole diameter.
If you prefer, and can replace it, instead of side view do the section.
It seems to me an all-somato banal piece that does not require great maneuvers and not even so many odds to cross and create trouble. if I still have not understood your question I am going to and wait for the continuation of the post and your result
I came to the coffee and digestive so... prosit

you have three views:frontal (in which you see the central ferritoia), lateral (in which you see the radius of the cap), plant.

you have two axes that intersect at one point and that of course they are not comlanaries.
Do I understand?

I think we're almost there.
in what she defines side view, she tells me to draw the axes of the holes and to quote the angle between them. That's what I thought I was doing in the first line. There is a problem though:
It seems incorrect to represent the axes in the side view, since the side view is a flat view that does not contain the axes of the holes. So you're proposing to draw some fictitious axes?
p.s. student law in my profile because I am currently pursuing a master's degree, so I am a student already graduated, but still a student and for me humility is a value.

exact! i have 10 normal holes at the spherical surface so 10 non-complanaries axles!

How much did you get in geometry?
Come on, I'm sorry, I'm trying to get rid of it, too. two axes intersecting at one point are common always. you can follow three roads:
1. take two holes and quota the angle between the axes on a view is the section of the object made on the passing plane to the center of the cap and the centers of the two holes. then put a note and write that the holes are all like two to two.pro: you have a mathematically elegant and impeccable representationagainst: you will be taken by your ass to life by the shop boss who, trivially, will have no way to measure and/or verify those odds.
2. in plant quoti the distance from the center of the floor sphere [equatoriale] on which all the holes lie, and then quoti the length of the arc between the centers. in a note write that the holes must have the axis pointed towards the center of the spherepro: continue to have a geometrically unexceptionable representation and give the operator the possibility to make a trace using simple mechanical blades.against:the workshop leader will come looking for you with the key of 24 and a false smile and will kindly ask you what the fuck you need the holes facing the center of the ball.
3. you realize that, given the reduced thickness of the sheet, the fact that the holes are with axes towards the center of the cap, or that they are towards the center of the above equatorial circle, at facts nothing changes, and then you do a section directly on the equatorial plane where you will draw and quota the various boards. on each axis you will put a central tolerance of 0.5° and so the operator will understand that the holes can do them with the hand drill and do not need a five-axis working center and an aerospace engineer to realize that set of holes.pro: for today you will avoid meeting the chief workshop, which notoriously is part of a bad category of people. you will also pay the realization of that piece at least one third.against: you gave up a requirement that could be of vital functional importance.

30 also in geometry :d
Of course taken at two to two, the axes are flattered, but taken together, they are at all!
However geometric disputes aside I think that you have centered in full the answer and probably in the end I will follow the third road that indicated, in order to avoid shoots of wrath by shop leaders (it is perhaps the most rational way since the convergence of axes in the center of the spherical cap is not a functional requirement)!

In fact, they lie on the surface of a cone of which you could quote the opening in steradianti...no, I'm joking!
Well, I'm glad, but on the forum let's say you.

Well, I didn't realize that they converged towards the center and considered them all on a floor.
