I think perhaps the intent of my post was missed ... it wasn't to debate the issue of "fixing" drawings, but rather why "fixing" in one aspect is regarded as acceptable. There have been at least 2 other discussions on this board (I'll not provide links ... I am sure those who are interested can find them) that were blasted by lots of folks. In those instances the data in the drawing was neither desired or required by the user (even if it is useful), but the mere idea that the data was put there by someone for some reason, thus it is given a sacred level. It is that inconsistency that I am having issue with ... and remember, I do agree with the decision to blast the AutoPlant data.
So far as the dictionary corruption observation is concerned, without corroborating data, I wouldn't know .. but I wouldn't dispute that anyway ... in my opinion, when AutoCAD (or any vertical app) allows data to be added into infinitum, I think the problem is more likely a corrupted application and not necessarily a corrupted drawing.
Anyway .. since it appears as though it is preferred to continue beating this poor equine, I'll comply for a bit longer.
