How do I use filter selection

We have discussed about using Quick Select before. But there is one more utility that you can use, not as pretty as QSELECT. FILTER command offers a dialog box that might also scary when you first see it. But after you use it for a while, you may don’t want to use QSELECT anymore.

The advantages of using FILTER are:

1. You can set multiple conditional filters at once. QSELECT only allow you to apply one conditional filter at a time. Then you need to apply another filter to your selection.

2.You can save the filter setting and use it again later. Let’s see how it works.

Using Conditional

You can open your drawing. Type FILTER then [enter]. Filter dialog box is loaded.
Now if you want to select all objects that the color defined other than by layer. You can simply add this line.

**Begin NOT

Color             = 256 - By Layer

**End NOT

You can do this to select all objects that’s not using ‘ByLayer’ color, and change them to ByLayer.
You can add more conditional for complex objects. Let’s say you want to quickly select all circle and lines, and the color must be red. Then the conditional lines in the filter must be:

**Begin AND

**Begin OR

Object           = Circle

Object           = Line

**End OR

Color             = 1 - Red

**End AND

Saving Filter

Now, after you save some filters, you can quickly select your objects with selective properties in just a few clicks!
