Hi
Henniger123, it's the way to measure the parallelism.
Here, you measure the parallelism of the cylinder to the axis of A, in a plane parallel to B, so the defect in the other axis is not dimensionned (it's like a 2D parallelism, from a projection)
(the tolerance zone is oriented from another feature, established from an extracted feature of the workpiece, identifying the orientation of the tolerance zone.)
You can find the same symbol, with only one arrow (triangle) which is an intersection plane, with an arrow which is the direction feature indicator or a circle which is the collection plane indicator.
