When working with models that require complex or free-form geometry, such as those with multiple paths and cross sections, you may want to experiment with swept, lofted, and BlueSurf features, and compare the results. Depending on the input geometry and options you set, one feature type may you give more desirable results than the other. The following outlines the major differences between these features.

• Swept features must always have at least one, but not more than three path curves. They can have one or more cross sections.

• Lofted features must have at least two cross sections. They can have no guide curves, or one or more guide curves.

• BlueSurf features must have at least one guide curve and one cross section, or at least two cross sections and no guide curves. You can also create new guide curves and cross sections dynamically within the command by intersecting a BlueSurf feature with a plane.
