It sounds like an issue with the video processing.
Make sure the video card has the latest drivers, check to see if it is on
the Certified Hardware List for AutoCAD 07.
Make sure that Hardware Acceleration is enabled (type 3dconfig & hit the
Manual Tune button), it's disabled for my video cards out-of-the-box.
I have never had a great deal of luck w/ polyface meshes, especially on
large or complex tins. They have always dogged my pc down fast. Do you have
the issue if you view 3dfaces instead of a polyface mesh?
SP 2A was just released and it suppose to address a number of root AutoCAD
07 bugs. Do you have this installed?

I'm running Land Development Desktop Companion 2007 and I'm getting an
error, "Heap error detected. Would you like to break in the debugger?" It
happened after I created an Alignment, then ran the profile. It prevented
saving the drawing, and came up when opening another drawing within the same
application. Now it appears whenever I try anything.
