Is there any way to get the extents (bounding box) for an attribute (and/or a block). i.e. the MinX, MinY, MaxX, and MaxY values |

Right now you have to loop through all the entities and calculate that yourself. You will also need to account for blocks and inserts, including rotation & scale, to get the full extents. When I've needed to calculate the bounds in the past, especially multiple times, I've used QuadTrees to query the objects extents. |
