How to create a face following the geometry of a body?

[Anonymous]

So I have a model of a car that I am trying to section to create molds. I have a sketch projected onto the car body to show where a sample section could be, but am not sure how I could create a face that follows the geometry of the car body properly.

You can use the Split body command to create sections.  The command can use planes or sketch geometry for the splitting tool.
