You could use another plugin has similar functionalities. (86.7 KB)

OK thanks!

But how do you select your surface, I can’t select here, can you show me please??

thanks again!

My new surfaces were internalised in the surface params connected with S1 & S2 inputs.
Bake them and verify if you want. And beware they should be “Untrimmed Surface”.

I explodes it before and select the S1 & S2 but the result is not OK!

can you do a video please!


I already mentioned about that.

Yes I saw well but how should I make the surfaces linear?

I Don’t know very well Grasshopper, I’m new!

If you’d like to know about the Trimmed or Untrimmed surface, see the link bellow.

Hello HS_Kim!

I read what you recommended me but until now, I can’t seem to understand the processus!

Please can you sent me a vidéo showing the processus to select the surface S1 & S2, because here I am Always having the same result , thanks!

Preparing “Untrimmed Surface” isn’t that difficult right? Just use Edge Surface or Ruled Surface whatever you like… (55.0 KB)

Ok thanks a lot!

it’s working know…

Hello HS_Kim!

Does this program work if I have to intrude into my main model??

I’d like to make the cut of my main model like:

But the problem is when I bre my cut surface I can’t have the same result like before:

can I have to modify Something ??

I don’t know how you made your base brep so, as long as you change your base brep every time, I can’t show you one general solution. You should change some parameters by yourself. (49.6 KB)

Your solutions seems great but here I can’t have the same result, I Always have discontinuities Lattices along my brep surface like:

Have you add Something else to give that:


I already said.
I’d like to advise you to make two untrimmed surfaces directly from rhino using your Brep edges.
You can simply use Loft or Ruled Surface command in rhino.


I did not even yet select my surface I just loaded the program and the rendering is as we see below:

and when I select, I have that:

I also tried to use loft and Ruled surface but the rendering is not good
