When working with swept features that have more than one path and cross section, you should consider drawing sketches first, rather than drawing the profiles as you construct the feature. This approach can make it easier to construct and edit the feature.
You can use a different method for each path and cross section in the same swept feature.
If you use sketches, you can only select elements from one sketch for each cross section, and you cannot combine elements from a sketch with model edges in any cross section.
Regardless of the approach you use, the feature is associative to the elements you select to define the paths and cross sections.
