AcDbEntity and Audit

[Anonymous]

Hallo!

Have a drawing with a 'corrupt' block reference. Runing audit fix the error.
But I want to handle the 'corrupt' drawing element in my arx program (there
are too much drawings and the 'currupt' efffect is very, very seldom, so it
is a performance problem to audit every drawing manually or by program).

I can catch the 'corrupt' block reference, because, the
AcDbBlockReference::blockTransform() (need the transform matrix for further
calculations) results to '1.#QNAN00000000000' in the dialgonal matrix
entries. But how can I 'heal' the block reference?

Thanks, Tim
