I have a problem with creating a loft in Grasshopper.
I’m trying to generate a complex surface lofting a set of curves.
Everything looks fine when I look at all the curves that are joined (they are ordered).
Maybe a problem with curve directions?
Crenel’s direction seems to be good

Checking the individual Loft Options shows that setting Rebuild to 0 makes the difference.
Your photo gives the impression you will be using a clay printer. I’ve made several shapes like that with my FDM printer. For me the key trick was how to turn the horizontal Loft control curves into vertical ones. I did this without fussing with the seams at all, but that may not work for what you are trying to do.
So…Here is my initial structure with crenels associated with the Leopold concept…I think it’s ok.
Thank you very much for your help.

Thanks to Leopold and Arthur for showing a nice way to make and use crenelated curves. I had come up with an ugly approach the used substituted points in an initial smooth curve, but it wasn’t nearly as flexible as the one used above.
After some tweaking to support both XY and XZ planes I used this new method to make this:
It is a RailRevolve using different crenelated curves for both the rail and sweep curve. Because my printer cannot print unsupported near horizontal surfaces I may have to change the overall shape a bit, but this one looks pretty close to being OK.
By inserting the curves as you can see from the image you get a good result.
The vase is made up of two surfaces which, when joined, form a closed brep.
For the external part loft with Loose option.

ouahhhhh, your idea is excellent, i did the insert of curves but the result was bad…because i didn’t use a guide…points along curve after…very good…thanks a lot. you’re a master
