AutoCAD Solid Volume Errors

[gtilt]

Hi, I would just like to find out if anyone else is having similar problems with AutoCAD 2004

When subtracting a solid from another (i.e. decreasing the size of the original solid), it sometime happens that the volume of the original solid increase (by as much x10 000 in my case) rather than decreasing as is should. Seems a little strange. The file has been audited, purged etc. but the problem still persists

I've been doing a lot of volume work with solids recently for a project I'm working on.
I can't say that I've noticed the problem you mention.

can the problem be repeated ?

I think the file may have become corrupted, even though there were no errors when an audit was done.
I was able to repeat the problem (actually couldn't stop it from occuring) and eventually had to copy and past the solids that didn't have any problems into a new drawing and continue.
Strange thing was that if I copyed the solids from the new drawing into the corrupted one say three times, I would get different volumes for exactly the same solids and these volumes would also differed from volumes calculated in the new drawing

I am a mining engineeer, and I will like to learn, the procedures and/or be re-directed to the appropriate links, to calculate the volumes of excavation and /or ramps using Autocad 2000. Thanks-any help would be appreciated.
