This list allows the user to select multiple areas for the functions Delete, Active, Passive, and Show selection <. If you want to change the area, only one region can be selected.

Object handling

Window handling



AutoCAD does not allow more than 255 lines in a list to be selected at a time. If more than 255 objects are selected, a message will appear at the bottom of the screen, that the list cannot be used directly. This means that more than 255 objects cannot be selected by clicking the list and that the functions Select All, Invert, Reset, and/or From screen have to be applied when more than 255 objects are to be selected. We cannot see from the list which objects are selected, but Selected will show the number, and the functions for the relevant objects do work!


In the box Filter, we may specify which hard ground regions are to be shown in the list.
