Knee wall in cape cod roof

[Lee1113]

Am I wrong to assume that when I select knee wall for a wall, that it will be a shorter wall?

I'm trying to place dormers in a cape cod roof!

I have Home Designer 7.0

According to the software's Help:

Check Knee Wall to define an interior wall whose height is defined by the roof plane above it, not the ceiling height. Knee walls are usually found next to top floor Attic room areas.
