Remove Raster Using Existing Vector Geometry

The Remove Raster Under Vector tool allows you use existing vector geometry to remove portions of the underlying raster image.

For instance, you could use AutoCAD tools to trace a complex spline in your image, then use the Remove Raster Under Vector tool to remove the traced raster.

Depending on the settings in the Raster Design Options dialog box, the removal is accomplished using either rub or raster entity manipulation (REM) methods. If you choose the REM removal method, raster intersections are preserved. For more information, see Remove Under Method.

Note: The Remove Raster Under Vector tool does not remove raster data within the selected vector, only around the selected vector. For instance, using a vector polygon will only remove the raster around the polygon segments, ignoring the raster data within the interior of the polygon.
