The Selection filter feature Selection Filter button allows specific selection of drawing entities based on various entity properties. For example it is possible to select all lines that are red and located on a certain layer (i.e select only red lines on the 'detail' layer), or select everything that is not a line or an arc. This allows selection of entities based on the defined criteria whereas the only other way to do this would be by normal selection techniques (one at a time and by area).

The selection criteria set applies to the current Selection set (so it is possible to apply your selection filter to part of the drawing) or the entire drawing if no entities are selected. When selected the following dialog box is displayed.

Selection Filter dialog box        

For an entity to be selected it must match ALL of the filters listed in each row of the window at the top of the dialog box. In the example above the first filter is  'Entity = Arc' . The second filter is'Colour = 1'. If the 'OK' button is clicked with this selection criteria then only red arcs within either the Selection set or the entire drawing will be selected. The colour number refers to the colour currently assigned to that Pen number.

The area of the dialog box below the top window entitled 'Select Filter' is used to modify the list as follows.
