Hi guys Im trying really hard to find the best way to model an egg chair, and I came across a tutorial from rhino: https://youtu.be/1-rQqb921w0?t=9m4s That given 2 curves it does the wizardry of bounding them together.

Does blender have a similar modifier, curve option that can perform the same?

Thanks for the help

    $\begingroup$ Rhino is a NURBS based modeling application, Blender has very basic support for NURBS, with limited tools , it can't be modeled that way in Blender. Look into the Bsurfaces addon for similar workflow blenderartists.org/forum/showthread.php?225190-Bsurfaces-v1-5 or model it properly using traditional mesh subdivision. $\endgroup$

  • $\begingroup$ @DuarteFarrajotaRamos True, I'm just trying to see if anybody as a trick that I'm missing to see... If there's none I will continue with the mesh subdivision ;) (4h into it right now...) $\endgroup$

  • $\begingroup$ Look into the linked addon, or consider trying third party software, if that is an option. MoI 3D is a great and simple NURBS based 3D modeling tool. It is commercial but relatively cheap for its kind $\endgroup$

  • $\begingroup$ do you mean using a curve that represents the top view and a curve that represents the side view and combine them (so similar to the boolean intersect)? $\endgroup$

  • $\begingroup$ @FacebFaceb , I don't really understand how intersect would merge the two views like in the video. But the main concept, answered by Duarte, is yeah have to lines, or beziers and make a different path between the two. Thought i already model the chair (good old mesh subdivision) my question remains if someone know a try of doing that in the video above. $\endgroup$

in sverchok, i use pink curve's z position and blue curve's xy position to create a new green curve. enter image description here

In the video the shape of the armchair is not close to the original example, which is OK if all it intends to do is show a technique.

In Sverchok we can use interpolation node mk# to interpolate the points of multiple curves, by sampling them along their trajectory. If you observe closely the videos, he made a row of curves along the exterior profile, those are all we need to achieve the same result. The outer curve profile (egg shape), can be generated via the math nodes.

enter image description here

In sverchok we can do the above and it all stays parametric, or use Blenders bundled "looptools" add-on at the cost of parametric interaction.
