Problems with Curve Bevel

Hi guys,

I’m having problems with the curve bevel while building the baseboard for a room. I have the room perimeter curve, and the baseboard profile; when I apply the curve profile as bevel to the curve perimeter, sometimes it works as expected, but others it is facing the wrong direction. I’ve tried Tilt, but that seems to just rotate the curve around its pivot (I might be wrong here, for I didn’t fully understand the feature).

Is there any way to change the direction of the curve bevel is facing (in/out) without moving the curve, much as we can flip a face normals?

Thanks in advance for all your help.
