In OpenPlant Isometrics Manager 2024 there is a technology preview for pushing generated isometrics to PlantSight. Currently, what you can do with isometrics in PlantSight is view it in the same port where 3D model is presented and reading properties from the physical schema when you click on a piping component.
If this technology preview makes it to an official functionality, what about adding cross-probing to it, so when you select the pipieline from the isometric, it zooms & highlights the according pipeline inside the 3D model or P&ID (and vice versa).
