He agreed with the colleagues' answers

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. AutoCAD identifies the problem and correct it by removing the corruption with the drawing parts. The poly-line provides only the provision of using one vertex and the vertex can be added on run. It involves adding of the vertices to the poly-lines with a provision to add additional vertices.

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.
