Hi,
i have some dwg's that should only be about 15k in size. they are about 1mb all purged, wblock the whole plan out and the new dwg is 1 mb. I can erase everything in the dwg and it is still 1mb purged. It is not all dwg's just some. i can't find what is loaded that is making them so large. ever here of this? i am on 2002
it is a real problem as the dwg's are xrefs of unit plans and have to be e-mailed.
thanx
Dave
Answer -
Some drawings could have originated with a product that puts proxy objects that are invisible into the drawing. It's data that is meaningless without the original AutoCAD vertical product that made it.  Such programs are Land Desktop, Architectural Desktop, Mechanical Desktop, etc.  There is no way you can purge these objects out.  It's best to start fresh than to SAVEAS from one drawing to another.  You might try inserting the WBLOCKed objects into a new drawing session to see if that reduces the file size.

Answer
You got lucky.  Sometimes that stuff doesn't get purged via DXF anymore.  Count your blessings. And good for you that you were resourceful enough to figure out what to do.  I probably would have not worried about the file size, since HDD's are so big now.
