Using the Layer Properties Manager

Knowing every detail about NCS is not necessary to complete the exercises in this book. As in the example you’re about to complete for working with layers,I’ll provide all the information you need to create layers inside the framework.
To begin creating new layers, take the following steps:
1. Open AutoCAD, and then open I05A-FPLAYO.dwg (M05A-FPLAYO.dwg)
—both imperial and metric versions are included in the Chapter 6
data folder. Make sure the Home tab is active and the Layers panel is
in the Ribbon, centered just above the drawing area on your screen.
2. Expand the panel and you will see that it contains several buttons,
two drop-down lists, and a slider bar for controlling layers, as shown
in Figure 6.4.

Several panels to the right is the Properties panel (see Figure 6.5),
with four drop-down lists for controlling colors, lineweights, linetypes,
and plot styles, and a slider for transparency. Once again, best
practices discourage changing the properties of individual objects to
anything other than ByLayer/ByBlock unless absolutely necessary.

3. Click the Layer Properties button on the left end of the Layers panel
to open the Layer Properties Manager (see Figure 6.6).

Notice the large open area in the middle right of the palette with
layer 0 listed at the top of the Name column. This is the Layer List
box. All the layers in a drawing are listed here, along with their current
states and properties. I05A-FPLAYO.dwg (M05A-FPLAYO.dwg) has
only one layer so far.
The Layer List box is where you will manage the properties for each layer in a
drawing. Status properties such as On/Off, Freeze/Thaw, and Lock/Unlock control
the visibility of a layer. By contrast, a series of appearance properties including
Color, Linetype, Lineweight, Transparency, and Plot Style control how a layer
will display in a drawing. Don’t worry if these properties are confusing right now;
the upcoming exercises in this section explore their functionality in detail.
To the left of the Layer List box is the Layer Filters tree view box, where you
can define which layers to display in the Layer List box. The Layer Properties
Manager has nine buttons along the top to perform layer and filter management
tasks. You’ll see an Invert Filter check box at the bottom of the palette.
The Layer Properties Manager is considered modeless because you can leave
it open while you continue to work on your drawing. This means that you can
leave the palette open and move it away from your drawing area, where it can
remain constantly open, waiting for you to input changes without having to stop
to open the palette each time. Being modeless also means that your changes are
instantly reflected in the drawing area, and you don’t need to close the palette to
see the effects of your actions.
