very large (normative) bending radius representation

[antonio_sc]

Good morning, I have a question about the technical design...I have a component with a very large bending radius compared to the other dimensions. . .
...if you want to use a sheet a4 and represent the location of the center,the same would go out of the sheet...I usually am used to do this way (leaving that the location of the center is on the symmetry plane of the component):
In this way I would be able to represent another view in sheet a4.. but I was "invited" to represent the whole in this way:
using a sheet a3 or a2 (just see that the center falls on the symmetry plane). Now.
what does the legislation provide for? can one exclude the representation of the center of the arc if it falls on the symmetry plane (indicating only the radius size)? even because if I had an even greater curvature radius I would risk taking the first stratagem anyway..you want what you say about it?

thanks for the answers

2 is correct.
you can also represent the center of the arch and quote its position (in case it is not symmetric).

the norm provides for both representations. If you do the broken one, I suggest you put in the center quotas, even if for use and customary if not indicated they are on the axis.
only one demente uses an a2 to show the center....it is important to use sheet sizes with intelligence.
