The Advanced Selection tool is a precise way to select objects with shared tags, categories, part numbers, or levels. Besides being used to move, delete, rotate, and edit, selections are used to apply Schemes and Part Tags, or new categories. 

A simple way to select objects is simply by clicking them in the drawing area. You can also use the rectangle select or lasso select tools. But the Advanced Selection tool is best for when you need more control or are in a vast drawing.

Get to the Advanced Selection tool from the Tools drop-down menu, or click Alt + S. 

Once it is open, it can be expanded or collapsed: 

Expanded		Collapsed

Use the double arrow icon next to the X to collapse or expand.

Click-and-drag the header of the dialog box to move the tool anywhere on your screen.

There are three parts to the Advanced Selection tool: Selection Criteria, Selection Query, and Selection History.

Selection Criteria

In the Selection Criteria section you will see the types of criteria by which you can pick objects in your drawing. You can choose by Categories, Part Tags, Levels, or Part Number. If you do not see one of these criterion present, just click Add Criteria to add it to the list.

If you do not need to filter selections by a certain criterion, simply hover over the name of it and click the red X that appears.

Click or hover over the name of one of the criteria to filter which objects will be selected. For example, if you want to select all dimensions in the drawing, click Categories, then find Dimensions and turn the toggle switch on.

You can select by multiple criteria at once. For example, if you want to select all seating found in the Room1 Part Tagged area, you can filter your selection with Part Number and Part Tagging. Follow these steps:

1. Open the Advanced Selection tool from the Tools drop-down or with the shortcut Alt + S. 
2. Click Add Criteria to add Part Number to the Selection Criteria.
3. Click Part Number and turn on the toggles for the seating you want selected.
   
   
   
   
4. Click Part Tagging and turn OFF Room2 and Room3.
   
   
   
   Trying to select Room1 by turning all off and just turning Room1 back on will negate the Part Number selection from before. Simply turn off the unwanted Part Tags to keep the Part Number criterion active.
5. The result is that all symbols with the chosen part numbers that are in Room1 will be selected. 

Selection Query

The Selection Query is a powerful selection tool that allows you to set your own parameters. You can type in criteria and decide if you want your selection to equal a certain value, NOT equal a certain value, and other operators. 

Selection History

The five most recent selections are stored in the Selection History section. This includes selections done with any other selection tools as well as selections made with the Advanced Selection tool. Click on any item in the list to repeat that selection.

When the Advanced Selection tool is in the expanded mode, all five stored selections are listed:

When collapsed, only the one most recent selection is available:

Click on the tag icon that appears to the right of an item in the Selection History to keep it pinned to the history. This makes re-selection even easier!

Closing the dialog will not clear your selection history, but it is updated as you continue to select different components in your drawing. Each drawing has its own selection history, so it will change when you switch between drawings.
