Just like available in the Microstation and Bentley Civil environments, it would extremely valuable if Terrains brought into Design Review had the same options to toggle on/off Triangles, Contours, Flow Lines, Breaklines, Spots, etc.
This would be an extremely valuable aid for Design Review and add an exponential amount of design information available to the reviewer.
Couldn't agree more. Have created scalable terrain meshes for the last 2 iTwin project and having the ability to enable contours (and set intervals and symbology) - just like in MicroStation - would make that data object so much more valuable.
