I've noticed a change with the representation rules. When two edges overlap in the model, it seems like Draw is now prioritizing geometry that is higher in the model, rather thank the order of the RRULs in the RRST.
For example:
1) A concrete pier is drawn first as a light grey line.
2) the concrete slab profile goes around the profile of the pier. This is drawn heavy (pink-ish color)
Traditionally I would expect the concrete slab line to be the priority and "draw over" the light grey lines of the piers and curbs. But the opposite is happening even though the slab rrul is higher in the RRST. I feel like AVEVA has added new functionality to handle overlapping lines.
