I am having trouble placing curved semilandmarks through resampling. After creating my curve and resampling (making sure to select constrain to surface), the new curve is beneath the model. ![Screenshot (1)](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/0/4/048b5bae3ffd433ba2e9bf0c9c1c3d2a43465e53.png) ![Screenshot (2)](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/0/2/021ba9e0522e073a222739997e973f7a79eaf14c.png) Also, I am unsure of how to place surface semilandmarks only on the distal articular surface. I am not sure if I need to combine the landmarks into a single dataset or place the curved semilandmarks first to delineate the surface I want covered. ---
