As you might have already noticed the Layer dialog box has changed in AutoCAD 2005. It takes many of the things that were hidden in nested dialog boxes and brings them to the top. Not only did they redo the Layer dialog boxes, but they expanded the ability of the Layer Filter dialog box so it allows easier access and setup of Layer Filters.
The left side of the Layer dialog box is where the Layer Filters are now at. AutoCAD by default now builds a layer filter for any Xrefs that are loaded into the drawing which makes the organization of Xrefs much nice in AutoCAD 2005.
Tip: Select the Xref branch in the Layer Filter tree and then check the "Invert Filter" box in the lower left corner of the Layer Properties Manager you can supress the display of all the layers associated with an Xref that is in the drawing. Then check the "Apply to layers toolbar" box and click the OK button.
Tip: You can display or hide the Layer Filter Tree by right-clicking over the Layer list and selecting the "Show Filter Tree" option at the top. This will give you more room if you are someone that doesn't like to see the Layer Filter Tree on screen. The Layer Filters are still available by right-clicking over the Layer list. If you right -click and go down to the Layer Filters selecttion, it will open up and display all the Layer Filters that are setup.
To create a new layer filter follow the setps below:
1. Launch the Layer Properties Manager dialog box by typing in the command "LAYER" at the command line or any of the other methods that you know.
2. Click the "New Property Filter" button located in the upper left corner of the Layer Properties Manager.
3. Provide a name for the Filter. This is the name that will appear in the Layer Filter Tree.
4. Change the other properties according to the types of Layers you want to appear in the Filter. The botton protion of the Layer Filter Properties dialog box gives you an idea of what the Layer Filter looks like in action so you don't have to go back and forth to see it in action.
