“Use DrawCompare to compare all entities between two drawing documents. The differences between the drawings are displayed in color codes. You can also compare a detached drawing to its associated fully-loaded drawing. DrawCompare compares the bitmaps of two drawings at the bit level. Only visual changes are captured when the drawings are compared. For example, if you move an annotation 2mm to the left, this change is reflected in the comparison. Conversely, if you change a custom property such as the Description, this does not reflect in the comparison.”
