3d shape curves

[User1]

help! I do not understand the operation of the curved silhouette command! you use to make plastic molds, calculate the partition line between piece and mold! Can any of you please give me some examples of its operation? on what type of model can you apply? Thank you!

In short, how should the command be used?

serves to determine the horizon line on a surface compared to a direction.
Imagine an egg depending on where you look at it has a different horizon curve.

so in this egg image the yellow line must be the direction of extraction, while the purple one is the line of partition?
