Depending on the surface geometry, the silhouette surface may or may not be selected. Creo is pretty good about it, but some still can't be used.

You can, however, make a copy of the surface and use the trim tool to trim it back to the silhouette edge. You need to select the surface quilt and a plane first, then look for the silhouette button on the trim toolbar.

could you please provide a image or a part file.

i do not think there is any issue with use edge option...it can surely pick outside curved edge.

    Try hovering over the the edge you want projectet, then right click and then left click.

    Sometimes I need to right click before left clicking to get the edge that I want.

    Thank you for all of your responses, i think all methods is helpful. but i would like to say it will works on a simple curved surface, not works on a little complicated surface. kindly please download the Creo 1.0 part file i uploaded:https://www.box.com/s/i3kv06yw8h1meqhssbsr, i would like to trim the looped surface and by utilizing the silhouette edge when viewing from front plane. but the silhouette edge seems like a looped 3D curve, so the trimming with a plane would not works. what tool can be used? please let me know if you have any ideas. thanks for all of your help.

    I think you are trying to extract the silhouette curve which is not an edge. However, I can see many ways that you can make this work for you.

    I would suggest making an extrude surface in profile and then intersecting the two surfaces. Not you have a feature you can project.
