hi david, thanks for the reply. looking forward for the both sides option.
let me clarifiy my cap problem. i uploaded a screenshot here: http://grasshopper3d.googlegroups.com/web/GH_ExtrudeCap_question_.jpg?hl=en&gda=kKq9d00AAAC19Ve3i4OoV9kZmG4Q4mscTPHNrS-HQS0FPHv2VOlJXEqBPVXaIbE-8D9fMzu99UdSl2-HdnkvTZuwNn829p6E5Tb_vjspK02CR95VRrtmeQ if the planar surface has holes GHs extrude component refuses to work because "the BReps edges could not be joined to a single border curve for extrusion." if this is a condition, then it's obvious why this setup cannot work. see the result of what rhino _Cap does for comparision. that's what i try to achieve. is it just me, am i missing sth? BTW, this was done in version 0.50099! best, frank On Apr 3, 12:40 pm, David Rutten <[email protected]> wrote: > > add an option for °cap° and °both sides° to the extrude component. > > explanation: > > If you extrude a surface instead of a curve it will be capped at both > ends.
