Adesk::Boolean isModifiedGraphics() const;
Description
Returns Adesk::kTrue if the object is derived from AcDbEntity and has had either an assertWriteEnabled() called since it was opened (which would indicate that a member function that can change its data was called), or its recordGraphicsModified() function called with an Adesk::kTrue argument value.
Otherwise it returns Adesk::kFalse.
