You can choose a gradient that transitions between shades of a single color by clicking the One
Color radio button. This turns on the Shade And Tint slider and disables the Color 2 swatch.
When you select the Two Color radio button, the Shade And Tint slider is disabled and the Color 2
swatch is displayed.

As mentioned earlier, you can choose from a set of gradient patterns from the Color option.
The Angle pop-up menu gives you further control over the gradient pattern by allowing you
to rotate the angle of the pattern. The pop-up menu is set to 15-degree increments; however,
you can type in a value in the text box. The Centered option places the center of the gradient
at the center of the area selected for the pattern. This option is a toggle that is either on or off.
To place a gradient pattern, select a set of objects or a point in a bounded area, just as you
would for a hatch pattern.
Tips for Using Hatch
Here are a few tips on using the Hatch feature:
•u
Watch out for boundary areas that are part of a large block. AutoCAD examines the
entire block when defining boundaries. This can take time if the block is large. Use the
Select New Boundary Set option in the Boundary Set option group to focus in on the
set of objects you want AutoCAD to use for your hatch boundary. If you desire, you can
turn off the preview by using the HPQUICKPREVIEW system variable. ON turns the
preview on, and OFF turns it off. You may want to turn this off if you are doing a lot of
hatching in large areas.
The Hatch feature is view dependent; that is, it locates boundaries based on what is vis-
•u
ible in the current view. To ensure that AutoCAD finds every detail, zoom in to the area
to be hatched.
If the area to be hatched is large yet requires fine detail, first outline the hatch area by using
•u
a polyline. (See Chapter 17, “Drawing Curves,” for more on polylines.) Then use the Add:
Select Objects option in the Boundaries group to select the polyline boundary manually
instead of depending on Hatch to find the boundary for you.
Consider turning off layers that might interfere with AutoCAD's ability to find a boundary.
•u
Hatch works on nested blocks as long as the nested block entities are parallel to the
•u
current UCS.
Space Planning and Hatch Patterns
Suppose you're working on a plan in which you're constantly repositioning equipment and fur-
niture or you're in the process of designing the floor covering. You might be a little hesitant to
place a hatch pattern on the floor because you don't want to have to rehatch the area each time
you move a piece of equipment or change the flooring. You have two options in this situation:
You can use Hatch's associative capabilities to include the furnishings in the boundary set, or
you can use the Draw Order feature.
