Hello, I'd need help on the projection on 3 floors: p.o.
I leave the figure with relative quotas.
the thing that I do not understand is the diameter of 108 and 110 mm towards the base of the mechanical piece that connect in the same place.
Thank you very much.

that design is already present mel forum
still attach your interpretation r then discusses it.

It is not very clear, but it seems to me that the ø108 identifies the final (virtual) edge of the conical tract in grey (long 95), while ø110 is the diameter of the cylindrical tract 8.
 
better if you learn to do the projections yourself instead of copying them, without even knowing if they are correct, because if you can't do this particular "banal" when you need to do one that really needs 3 views will be huge swarms... Let's figure out if you have to extract it from an overall.
 
the diameter ø108 is an apparent continuation of the cone until depth 8 of the worked area of the final part of the cone. serves to define the corner of the cone, which is not expressed.
if one is redesigning the component, it comes to the point that he lacks something, the angle precisely.

That's right.
However if he designed it especially with any cad it would clearly notice that the sketch does not remain completely defined.
 
I agree that the quota of 108, represents the theoretical point of the maximum diameter of the conicity, as reported by the drawing.
However, this is an internal point, which cannot be reached, not even for control, one can put in a program, but the tool does not reach it.
the r6 connection, then, is so great that it even more shortens the conicity.
it was more logical to quote the length of the conicity, which is about 83 mm, from which point the radius of 6 mm, up to obtain the altitude of 8 mm on the diameter of 110 mm.
as the maker of the piece should not be forced to make calculations, it was necessary to put the quota of 95 mm and at least the angle of 2,5° of conicity, which is the most important.
would have baptized the 83 mm quota, as seen from my design, without quotating its diameter of 108 mm.
I think they have created a kind of puzzle, it would be enough to ask where the tool stops when it performs the conicity.
