I want to align a city model with too many mesh volume building on a flat surface. They stand on topographic mesh so their bases have different heights. Normal for mesh points i use SetPt and select Z or Align from bottom but both did not work on this case? is there a way to define all bases and select all objects and say that align all on zero from their base points? Only way i know is to select them individually and align but with hundreds of buildings its kind of tricky. For any kind of help i would be really be appreciated!
