Working in U15 I've found two additions that aren't documented in the help
Microstation 08.11.09.919Power GeoPak 08.11.09.918Power InRoads 08.11.09.918
They have time to implement such changes no one asked for but can't add such change for which there is outstanding change request for years - https://communities.bentley.com/products/microstation/i/user_interface/place-cell-rotate-and-scale-interactive-method-missing
But nice catch to know when this is added just to not scratch head why it is not in earlier versions.
The Place Block Centered method was taken from another app and we cleaned up a few dialogs and tool boxes and forgot this one. THANK YOU!!
Will add to docs.bentley.com
