please ta a look at these ttwo pictures
i am trying to reproduce the cavities seen on the faces at the first image.
so far i have a
1.curve on the face (that came from a sketch projection on that face)
2.a sketch (with the grey lines, hope it isnt hard to see)that it is on a plane below the face.
the cut loft asks me sketches and not curves as end conditions.what am i doing wrong?
how should i aproach this?
