Unfortunately, we don't have similar option in 2021 version. We still have the traditional way drawing temporary detail line to snap to its middle point, then deleting it. A bit longer, but still valid.
Hi Nuono, this is one of the topics I am currently considering. I don't have a proper Revit LT workflow now - to create good visualization I export the model to external software and work from there. This is not flexible enough. Using Autodesk cloud renderer is very tedious and slow. What seems most promising is using Twinmotion.
