Getting the actual size of an object in Vue programmatically isn’t as easy as you’d think. You essentially have to get the BoundingBox of the object and work with that. So here we have a wind turbine object, and we have selected the pole and need to know (programmatically) how tall this pole really is. If you look at that z-value in the size pro…
