I recently adopted a dwg created by someone else. S/he make tonnes of surface and backup surface may or may not be useful which makes the file supper big, I have a hard time move around. So I am trying to delete some surfaces. But before doing that I wonder is there away to take a quick look of whether or not if a surface might be a dependent of another?
For example in excel when you click on a cell, you could Trace Precendents or Trace Dependents to see if that cell is related to another.
Is there an analog in AutoCAD to this?
