How to use IfcConnectionGeometry?

Hello guys! I am modeling information between two parts. From this modeling I would need to create “ppoints” (points to make the logical connection) between the parts.

Studying how to determine the relative coordinates of the points in relation to the “parent” item, I came to the conclusion that the ideal is to use “IfcRelConnectsWithRealizingElements”, because the connections have auxiliary elements such as screws, clamp, etc.

Thus, the attribute that specifies the origin point of the part and the connection point relative to this origin is “IfcConnectionGeometry”, which is optional.

However, I’m having a hard time understanding the ConnectionGeometry representation. I couldn’t assign value to it through modeling tools.

Could someone help me understand this?
