Thank you for your post.
We identified that the most likely and immediate need for detailed 3D is in relation to Specimen plants because these are likely to have a significant requirement for clash avoidance on projects. Adding more 3D content, the ability to control this per specification (above and below ground) and factoring in growth over time are all aspects we are researching and plan to include, initially within our KeySCAPE for Revit application that is planned for later this year. However, we are mindful of the impact on drawing speed and performance when modelling graphically complex landscapes in AutoCAD and/or Revit, especially when designing with large planting areas, mixed planting and when these are draped over a terrain.
