Each individual object in a drawing cannot exceed an uncompressed size
limit of 256MB. For example, a mesh object, when saved to a file and
compressed, might be 75MB in size while the same object when
uncompressed might be 257MB.
In these situations, the drawing cannot be saved to an AutoCAD 2007 or earlier
file format until the issues are resolved. You can resolve the size limits by
breaking the drawing or objects up into several drawings or objects.
NOTE When working with the 64-bit release of AutoCAD, you can work more
efficiently with large objects and drawings. However, the drawing files you create
might be too large to open with the 32-bit release of AutoCAD.
