data from the display. To reverse a rub, use the AutoCAD UNDO command.

2 Click Image menu  ➤  Remove  ➤  Polyline.

3 Select the first point of the line segment you want to rub.

■

Select additional points to rub more line segments.

Right-click and click Enter to end the polyline and rub the raster
underneath it.
