FIGURE 1.17 Using a different order of features for the same part
FIGURE 1.18 Compare the FeatureManager design trees for the parts shown in Figure 1.16 and Figure 1.17.
You can read more about reordering folders in Chapter 11, Editing and Evaluations.
In some cases, reordering the features in the FeatureManager may result in geometry that might not make any sense; for example, if the fillets are applied after the shell, they might break through to the inside of the part. In these cases, SolidWorks gives an error that helps you to fix the problem.
In 2D CAD programs where you are just drawing lines, the order in which you draw the lines does not matter. This is one of the fundamental differences between history-based modeling and non- history-based drawing.
