      Hi guys, as you can see I'm pretty new here, and I'm looking for some help. I'm attempting to extrude a somewhat complicated surface to a single point (I'll attach a picture.) I've been searching the tutorial and this forum unsuccessfully for about thirty minutes now and I was hoping someone would be able to help. What I would like to do is extrude my surface to the point where every cross section of the shape running parallel to the surface is a triangle. Are there any ways to do this? Thank you.


      This is the surface I would like to extrude.

        There are multiple (infinite) possible results (I'm not talking about multiple solutions).
        You may need to approach this manually for I doubt there is a plugin for such a specific case.
        One important thing that you haven't metioned is whether each of the three curved "sides" need to transform into their own straight side (edge of the cross section) and whether they all transform into these edges at the same cross section. Not one before the other.

          Do you mean like a conic develop-able surface (an edge from each endpoint around the face towards on point you've chosen)?

            Seems Tig has something for make that! πŸ˜„
            I must refound that 😳

            So radial Lines By Tig πŸ˜„
            Or radial fixed length for another variation πŸ˜„
            Maybe Projection by DIdier Bur can help for put a point! πŸ€“
            Just make faces after the drawing lines from a point to a surface! Or a perimeter! πŸ˜‰

              You say something tapered like this ? Better to put an image of volume wanted! πŸ˜‰
              (it's more easy for any body to link a little Skp format v6 for a more large audiance!
              Time's saver! πŸ˜„

              If you want a single point and regular angle you will managed for the more little thickness πŸ˜„
