I am a bit confused about a basic issue - what is extrusion and why we need to develop such a geometry type?
I remember at the early version of grasshopper we don’t have ‘extrusion’, we only have ‘surface’ and ‘polysurface’(brep). That is easy to understand. But now I realize that sometimes there is a type ‘extrusion’ (eventhtough it is just a simple surface with 4 edges extruded by one line. You cannot use a surface parameter to set it and you cannot use evaluate surface button… I have explode it to achieve what I want… and sometimes my old script fails now because this ‘extrusion’ type appears
I just wonder what is the benefit of bring this ‘extrusion’ object type.
Thanks for any hint.
