    Yes, just select the polygon(s) with the Digitizer Tool, then right-click and select the Advanced Selection submenu option to select all points within the selected area(s), then press Delete to mark them as deleted.

    Let me know if I can be of further assistance.

    Typically, this is the sort of thing you would do using the EDIT_VECTOR command, but we don't currently have a way to apply the advanced selection operations in a script.  The best option currently available is to use the EXPORT_VECTOR command with a polygon crop file, and specify the POLYGON_CROP_EXCLUDE parameter.  This will export your data, excluding the features in the crop file areas, to a new file.
