Section along a curve

[Mikus_Zaurins]

Hello

Is there a way to create a longitudinal section along a curve, which displays a surface and the given curve. I will be using this section in piping to determine slope for the pipe.

Hei Mikus -

Is there a way to create a longitudinal section along a curve, which displays a surface and the given curve.

There is no tool in Rhino that will create that automatically, but you could place vertical planes and get the intersections from those. Then rotate those to be in the same plane.

There was a recent thread with a similar issue here:

Need Assistant - How to create unfolded Cut Section

I just let it go, it came out pretty unnecessarily convoluted, but it might be a starting point [image] unfold_cut_thing.gh (37.9 KB)

Hi Mirkus - if I understand what you need you can try this:

1. Project your base curve through the objects

2. Make a line the length of the base curve

3. Flow the projected curves from the base curve to the line.

Here’s an example from the thread Wim posted - is that what you mean?

Thanks for the reply,
The proposed solution by Wim is basically what I am looking for. The only issue would be that I would need to edit the curve in the section view - the two views need to be dynamic. The reason why i want to project a surface along a curve is so that I can edit that curve relative to the surface in a section view.
