Extrude object in both directions

by Andrea Mosca

Hi to everyone!

I'm new to grasshopper,

I've extruded a group of objects along a vector, but i'd like the extrusion to work in both directions.

Can anyone help me?

 

Many thanks

 

Andrea

    I prefer this way, preferring to type as little expressions as possible in my definitions, that's just me tho.

      Hallo everybody,

       

      the ways our friend made are useful, but results always 2 geometries.

       

      i am wundering if there are some elegantly solution to extrude a brep in both direction but as ONE geometrie?

        "i am wundering if there are some elegantly solution to extrude a brep in both direction but as ONE geometrie?"

        The given solutions work but then trimming with breps doesn't work anymore - so that is good reason to develop an extrude function with 'two-sided' option as many CAD programs have as well. You keep the original curve as input and generate a single geometry.
