Extrude object in both directions

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

Hi Mario!

Thank you for the answer.

I tried to make a both sides extrusion the way you show me but it doesn't seem to work correctly,

Maybe there is a problem in my definition..

Now it works!

I set the F imput of the vector to Graft...

Thank you Mario.

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

Thanks Michael,

It could be a good idea for large definitions..

Cheers for this, just used it. Had another thought for large definitions.. Could Move resulting extrusion by negative half the original vector. (x*-0.5)

That way just one extrusion moved to appear like an extrusion both directions.

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 think this may require a two step process...first move your geometry by your vector*-1, then extrude it by your vector*2

as david says, or join the 2
