Position tolerance of an axis?
Position tolerance of an axis?
(OP)
Hello all,
In your opinion can I give a position tolerance of an axis?
I have defined the axis through 3 angles and one point (defined by 3 coordinates x-y-z), since this axis refers to a complex inclined geometry. So the next step would be the definition of the position tolerance on a diameter. Unfortunately I do not have a real diameter due to the complex shape. I can find much more easily an axis.
Thank you!

Generally tolerances are applied to features, not theoretical axis or planes etc.

There's also the option of using profile of a surface, which controls the location (and form) of the physical surface.

RE: Position tolerance of an axis?
You can only apply position tolerances to real features (of size). Can you apply profile tolerances to faces?

RE: Position tolerance of an axis?
The overall surface is a mix of splines which lead to a sort of ovoid-shaped tube.
Profile of a surface is surely the best way, but for the measurement a kind of "reference" axis or point is needed to begin with the measurement. That's why I'm trying to use an axis.
I hope I made myself clear. Thank you very much for your replies.
