using the CHANGE
REFERENCE DIRECTION button.
You can ask to project the curve
on all faces of a shape using the ALL
FACES button.

you to sew together the resulting curves.
In order
to make the sewing possible, all the

When you choose normal as the projection
direction, the projection is made normal to the face.
When you choose a projection
on one or several faces, the contour is trimmed on the faces.
