How to realize the evaluation of orientation plane in Hexagon?

ISO 1101:2017 new symbol Orientation plane how to evaluate in Hexagon？

  • As other people have already explained, the orientation plane modifier controls the tolerance zone orientation. In this case you have a per-unit flatness over a 75x50 rectangular area. The orientation modifier is stipulating that this 75x50 rectangular area needs to be orientated with the longest side of the rectangle parallel to datum C. To achieve this in PC-DMIS, you need to create an alignment and then set the unit orientation accordingly - see my example below...

    NOTE: PC-Dmis does not support a per-unit flatness on it's own, we only support the per-unit aspect as a refinement of a general flatness tolerance which is why my example shows two segments - the per-unit is the lower segment.
