★★★ How to select objects according to specified conditions in ZWCAD

Issue:

How to filter the selection set based on object properties or object types so that only the objects that meet the specified conditions are selected, and other objects are excluded from the selection set?
For example: How to quickly select all yellow objects in the drawing:

Solution:

• Solution 1:
  Input smartsel in the command line and press Enter to open Smart Select panel, then we can quickly select objects based on the specified conditions.
  
• Solution 2:
  Input QSELECT in the command line and press Enter to open Quick Select panel, then we can quickly define selection set based on the specified filter conditions.
  
• Solution 3:

1. 1. Input FILTER in the command line and press Enter to open the Graph filterlocate panel. then we can quickly define selection set based on the specified filter conditions.
   2. Create a list of requirements. We can add requirements from Object Type, Prop, Oper and Value, then click Add To List. We can also get object properties from the graph by clicking Add select object button;
   3. After clicking the button from Search in, Graph filterlocate panel will exit and promption Select Objects will display, we can select the objects that need to filter to create a selection set, then click OK to select the specific objects.
      
      Note for Solution 3:
      1. The filter can be named and saved for future reuse.
      2. When selecting the specific color in the Value item, the object color won't be filtered out if it's Bylayer even if it shows in the color we select.
      3. Compared to Quick Select, the  Filter way can provide more complex filtering conditions, such as you can use AND, OR, XOR and NOT to combine the different filter settings.
