Part IV: Creating and Using Libraries
The next step is to select the configuration, as shown in the image to the right in Figure 18.2. Not
all library features have multiple size configurations, but these do. The configs in this case are
driven by design tables. Select configuration 330.FIGURE 18.2Placing the feature and selecting the configuration
When you select the configuration, the interface changes. In this case, only a sketch relation
locates the feature; it is not located by dimensions. Notice that in the References panel shown in
Figure 18.3, there is an Edge entry with a question mark, which becomes a check mark after you
select the edge. This means that the library feature needs a circular edge to locate it. Notice that a
small window appears, displaying the library feature. You may not be able to distinguish it in
Figure 18.3, but the circular edge around the face that the library feature is on is highlighted in
green. This indicates that you need to select an edge that has the same relation to the library fea-
ture as the highlighted edge. Pick the circular edge of the part on the end of the cylinder where
you want to place the library feature.Next, use a rectangular part where the library feature is located by using dimensions rather than
sketch relations. Create a rectangle 1.5 inches by 2 inches and extrude it to about 2 inches in
depth.
