when you do the loft lines as you did for the yacht, I note in the file that the lines are Shapes.

How did they get converted from lines?

And do the ends of the vertical-ish lines have to touch the horizontal-ish lines. (Sorry, I don't know the proper ship building terms for them... )

The original drawing was JPEG image.
So I had to redraw all the section curves over this image in Inkscape.
Then SVG import in FC, and manual Placement for each object.

And do the ends of the vertical-ish lines have to touch the horizontal-ish lines.

No. Not here.
All the curves (profiles and the 2 rails) are discretized to points.
And this Point cloud is approximated to a surface with the Reverse Engineering workbench.

Hi Wilfried,
I looked at the video.
I see what you ask for.
This should be possible pretty easily.
I lack free time, but I'll give a try when possible.

Hi Chris,
I see you're currently working on the curves. Maybe my request from January 9, 2020 is now appropriate:

Many greetings

... 3 years ago this yacht was one of my first boat fevers as an FC freshman.
Today I tried to do this halfhull with Gordon - no result.
The same with a Loft on some or all frames - catastrophic.
ChrisG's shape is up to now the only form able to work with.

Hi Wilfred,
I remember I did a try, that didn't work well ...
Do you have access to the FreeHand BSpline Curve ?
It can do what you're looking for.
Select the vertexes, and create a FreeHand BSpline Curve.
It goes straight into Edit Mode.

You can then :
- hide the sketches, to have better view
- select the desired blue segments

Cbris_G, do you mind adding this to Curves_Workbench?

Hello, Chris,
thank you for the answer. This works great, just as I wanted it.
Are there any other functions besides the L button?
I figured out that T changes the curve.
Many greetings
