 Topic: AutoCAD 2007 problem - BIG circlesPosted: 09.Aug.2007 at 10:30 |

Hi there
Assistance would be gratefully appreciated!!
I'm working in AutoCAD2007 with a layout drawing for a construction site. The drawing consists of a hierarchy of external reference files, and in total is around 35MB.
I have a problem that in some areas small circles as part of an external reference appear in the main drawing much larger than they should be, both on screen and when plotted.
I have previously googled and found this problem described elsewhere, but without a prescribed remedy! The drawing is in milimetres scale for around 50Ha land, so it could be rounding errors for very large numbers describing circle parameters far offset from the origin.
I have tried to move the WCS in the main drawing (by selecting All and moving the would-be origin to 0,0), however the display order of the xrefs becomes jumbled and I admitted defeat at trying to resolve it.
Any advice would be gratefully received, as the problem makes the drawings look unprofessional!!
Thanks
Marcus (Lamplighter)

You should find the entity type of these circles (by opening the xref directly) - they are probably POINTs or block INSERTs. Scaling or PDSIZE can be the problem.

Vladimir, Papus
Thanks both very much for the replies. The circles appear as different sizes every time I modify an xref (even by drawing then deleting a line), so for sure it is a calculation problem in AutoCAD. I followed your suggestions. The system variable PDSIZE I discovered to be set as -2.0 - I changed it to 0.0 and the problem still existed, however when I changed this to +2.0 the problem disappeared!!
 I'm not sure exactly why this is so, but I'm happy nevertheless!!
Many thanks again.
Marcus
