I don't have experience with a slotted hole.  In the picture attached I'm trying to stress test the feature. Is is only providing a singular point in space at the equator of the feature?  Does this mean I can measure a position in both X and Y separately?  It appears it does not create any axis or line like a cylinder would so a positional measurement wouldn't pick up the slot if it is out of perpendicularity right?

 

In the second picture I'm using a method that seems to be working so far...I'm measuring an external slotted feature as a cylinder and applying minimum circumscribed to pick up the length via a diameter. Gets complicated passing along MMC to a planar position check, but I just use the user defined settings to do that.

Hi Tim,

The first thing to note is that the slotted hole feature is intended for use with sheet metal style components .

They then can be used to drive a grey value capture of the slot.

It was the case that mmc wasnt supported on this feature , i dont know if this has changed in recent times , but it does provide a possibility to return its position based on its point/line that it creates
