project a line on a surface

I try to project a line on a surface. I expect that the resulting curve would be connected to the line. But it's not the case.
 
Why? Thanks!

Hi,

 

In order to understand why you get what you get you could create a law extension surface normal to the surface through the projected curve. 

Another thing that reveals more info is using trim sheet. This will only work when you use "Extend Bounding Objects to Target Edges".

Ciao @surfactant,

 

Project Curve has many Projection Directions.

 

Look at the attached examples.

I guess, length of projected line before projection and after projection would be same over a projection surface!!!

Hi @DickBaardse   Thanks! A law extension surface is a great tool helping understand the issue.

 

Hi @Cesare   Thanks for your bonus examples! Very helpful!

 

Hi @Devraj_Mendon   I think youe guess is not correct. Please study @Cesare's example file carefully!

I know that this may sound lame, but have you turned OFF shading to see if the projected curve actually does come-up short?

Hi @JohnRBaker  Yes. The projected curve is too short to be connected with the original line. It's due to the shape of the surface. Thanks!
