Fast Select
The Express Tools include two commands to create filtered selection sets. FASTSELECT creates a selection set of objects that touch the object that you pick. You can create chains of objects to include objects that touch other touching objects. Choose Express➪Selection Tools➪Fast Select. GETSEL creates a selection of objects of the layer and object type that you select. Choose Express➪Selection Tools➪Get Selection Set.
Quick Select
As its name suggests, Quick Select is a quick, flexible, and simple way to create object selection filters. Use the FILTER command, which is covered in the following sections, to create more-complex filters or when you want to save filtering criteria for future use.
Start Quick Select in one of these ways:
✦ Choose Tools➪Quick Select.
✦ With no command active, right-click in the drawing area and choose Quick Select.
✦ Click the Quick Select button in the Properties palette.
✦ Type qselect ↵ on the command line.
Filter
The advantage of using the FILTER command over Quick Select is that you can create more complex filters and save them.
To create a filter, type filter ↵ on the command line to open the Object Selection Filters dialog box. If you’ve already chosen a command, type 'filter at the Select objects: prompt to create the selection filter transparently. The box at the top of the dialog box lists the filters that you specified.
System Variables : FILEDIA
The FILEDIA system variable determines whether a dialog box opens for commands, such as SAVEAS and OPEN, that request filenames. When FILEDIA is set to 1, the default dialog boxes open.
Even if FILEDIA is set to 1, if a script or AutoLISP/ObjectARX program is active, the command
prompt is used instead of a dialog box. You can still set the FILEDIA system variable to 0, but
be sure to change it back again at the end of your script or program. (Scripts are available in
AutoCAD LT, but not AutoLISP or ObjectARX programs.)
