Paramétrer la vue et une face de maille

[Loïs1 (Loïs)]

Bonjour,

Je suis nouveau sur grasshopper donc je découvre lentement comment l’utiliser.
Ma question est peut être bête du coup, mais je cherche faire avec grasshopper la même chose que sur rhino quand on sélectionne une face de maillage avec ctrl + shift, comme sur la photo ci dessous, et définir la vue du plan C (avec les petits avions) en vue du dessus

Merci d’avance !

Ou sinon est il possible de savoir quelle face j’a sélectionné sur rhino avec grasshopper ?

hi Lois, welcome to the forum
the forum language is English, so anyone can participate, I guess there might be a dedicated French-language equivalent somewhere?

I tried google tranlsating your message in english and italian, but I’m not able to understand what you are looking for… Grasshopper uses the very same Rhino viewport to show you geometries

My question may be stupid, but I’m looking to do with grasshopper the same thing as on rhino when you select a mesh face with ctrl + shift, like in the picture below, and set the view of plane C (with the small planes) to top view

You cannot reference subfaces with standard Grasshopper components other than with a Get Geometry component set to “surfaces”. Normally you select the entire Brep and then solve for the particular face using the Deconstruct Brep component.

Is it possible to select one face of a brep?

I’m trying to write a C# script that works on one face of a brep - I need to extract the plane of a planar face and check to see if some points are on it - and if some other faces are coplanar with it. But is there any way to reference a brep face in to Grasshopper? The obvious ways - ctrl-shift selecting in Rhino window to reference in Surface or brep primitive - don’t work. I know I can explode the brep and access the faces individually - and could then use a number slider for instance to sel…

Hello, sorry i saw a french message in a preview post, so i thought mine will be on a french server or something like that

And i dont know if i had to create another post for this, bt i want to create a button which appear on rhino and allows users to set an integer value, and another one to set a boolean value.
i didn’t find something like that, even with a plug in, but maybe i just dont use it well
Do somebody have a solution for this ?

Well, using GrasshopperPlayer in this instance would be ideal then, no?

You place a Get Integer and Get Boolean on the Grasshopper canvas (the Get Integer component vertically above the Get Boolean component on the canvas), and save the Grasshopper definition.

Then, from within Rhino, the .gh file can be called with the _Grasshopperplayer command in the command line, and the Grasshopper file will execute, asking for the integer and boolean values.

You can skip over the file selection dialogue by including the filepath in the command call: _GrasshopperPlayer “C:\path\to\your\file.gh”
