I’ trying to a tapered extrusion in Grasshopper for a casting process. Using the “extrude tapered poly surface” in Pufferfish.
Which I guess is using the ExtrudeCrvTapered command under the hood i guess? But this fails for more complex curves.
Probably there is no better way to do this with Nurbs right? Is it possible with meshes somehow? Or does anybody know a trick?
Depending on your input curve, ExtrudeCrvToPoint may be a suitable solution.
Thanks! But I need the same angle everywhere.
upload an example geometry?
Its just generic letters coming form Rhino Text Object. I need to extrude relatively far here compared to their overall size, (about 1:1 ratio between hight and extrusion length) and also with a fairly large angle of 15 degrees, and many of the extrusions are missing as a result.
can you -manualy- do it for just one letter? to show?

would like to extrude the letters of this size by 3 mm and 15 degrees
second one is with a failed extrusion

i think this is not possible. geometricaly

Maybe similar with BoxMorph?
I guess one thing is BoxMorph from a tapered twisted box and another thing is box morph from twisted box to twisted box (easier to scale bottom/top). Neither are ‘ExtrudeCrvTapered’, though - lol

Both ExtrudePt and Sweep1 yield nearly the same result:
