The SSX command is a handy alternative to Quick Select (Qselect) when you want to group similar entities (that is, objects that share a particular trait). SSX is listed in the Express Tool Help, but doesn’t appear on the menu. If nothing happens when you type SSX at the command line, try loading the command by typing:
Type SSX at the command line, or type (ssx) at any object selection prompt. Then select the property you want to match. AutoCAD creates a selection set that contains all objects in the drawing that share the property. For example, suppose you want to select all BOLT-14 blocks in your drawing. Once you start SSX, choose an instance of that block with the selection box. Press Enter. AutoCAD will display the number of BOLT-14 blocks it found.
If you press Enter again instead of selecting an object or text, SSX offers several filter options you can use to create your selection set:
Block name: Block name to add or remove
Color: Color number to add or remove
Entity: Object type to add or remove
Flag: Toggles the Entities Follow flag
Layer: Layer name to add or remove
Ltype: Linetype name to add or remove
Pick: Select objects
Style: Text style name to add or remove
Thickness: Thickness to add or remove
Vector: Extrusion vector to add or remove
Once you create a filter list, you can remove any filter by selecting its option and pressing Enter. If you select an option that is already in the filter list, your new value will overwrite the old value. You can have only one of each type of filter in a single filter list.
Caption: In the example above, the layer filter “pear” is changed to “apple,” and then removed entirely.
Once you’ve used SSX to create a selection set, you can run a new command and type P (for previous selection) when prompted to select objects.
Here’s a few more examples of things you can do with SSX.
Suppose you want to delete all Wipeout objects in a drawing. Type SSX at the command line. Press Enter twice, then E for entity. Type in Wipeout, then press Enter twice. Now type Erase at the command line and press Enter. Type P, then press Enter twice. AutoCAD will erase all of your Wipeout objects.

Suppose you want to export attribute information to a text file for import into Excel. Use SSX to group all the blocks whose attribute information you want to export. Start the Export Attribute Information Express Tool, then enter P.
