Hi there, I'd like to know if there is any way to extrude a mesh like this :

mesh {
triangle { <1,13.2146,-23.2146>, <3,14.286,-24.286>, <17,14.286,-24.286> }
triangle { <17,14.286,-24.286>, <19,13.2146,-23.2146>, <1,13.2146,-23.2146> }
triangle { <19,13.2146,-23.2146>, <17,14.286,-24.286>, <17,18.2146,-28.2146> }
triangle { <17,18.2146,-28.2146>, <19,19.2861,-29.2861>, <19,13.2146,-23.2146> }
triangle { <19,19.2861,-29.2861>, <17,18.2146,-28.2146>, <3,18.2146,-28.2146> }
triangle { <3,18.2146,-28.2146>, <1,19.2861,-29.2861>, <19,19.2861,-29.2861> }
triangle { <1,19.2861,-29.2861>, <3,18.2146,-28.2146>, <3,14.286,-24.286> }
triangle { <3,14.286,-24.286>, <1,13.2146,-23.2146>, <1,19.2861,-29.2861> }
triangle { <3,15.7146,-25.7146>, <17,15.7146,-25.7146>, <17,16.786,-26.786> }
triangle { <17,16.786,-26.786>, <3,16.786,-26.786>, <3,15.7146,-25.7146> }
triangle { <5,14.286,-24.286>, <7,14.286,-24.286>, <7,18.2146,-28.2146> }
triangle { <7,18.2146,-28.2146>, <5,18.2146,-28.2146>, <5,14.286,-24.286> }
triangle { <9,14.286,-24.286>, <11,14.286,-24.286>, <11,18.2146,-28.2146> }
triangle { <11,18.2146,-28.2146>, <9,18.2146,-28.2146>, <9,14.286,-24.286> }
triangle { <13,14.286,-24.286>, <15,14.286,-24.286>, <15,18.2146,-28.2146> }
triangle { <15,18.2146,-28.2146>, <13,18.2146,-28.2146>, <13,14.286,-24.286> }
}

I'd like to extrude it following the y axis.

I know I can do it using the "prism" fonction by keeping only the triangles
points without the y coordinate, but it's kinda boring to do it manually.

Maybe there is a solution to extrude every kind of 2D or 3D objects along an
axis !?


Thanks in advance for your reply.
