What are the features being corrected by AutoCAD?

- AutoCAD identifies the problem and correct it by removing the corruption with the drawing parts. - It involves adding of the vertices to the poly-lines with a provision to add additional vertices. - The poly-line provides only the provision of using one vertex and the vertex can be added on run. - The corruption can be neglected or corrected by finding out the exact location of the poly-line that has zero vertices. - The objects can be deleted after there is no use of it or can be removed if there is no use of them in the system.
