Extruding a planar object to create a 3D object

Hi everyone,

I have a 2D planar object which models the radial cross-section of a bowl:

…i.e. the right hand edge matches the edge of the bowl and the two left hand vertices mark the centre. What I want to do is take this object and extrude it about the y axis to create a symmetrical 3D bowl. Is there an easy way to do this?

Thanks a lot, please let me know if I can add more details to my question!

use the spin tool to generate the 3D model
then add the handle
see wiki page for the spin tool

happy bl

Fantastic, thanks a lot!

Some things should be noted:

  1. Your mesh doesn’t really look like a cross section of a bowl, but of some solid object.
  2. The central vertical edge is not needed, and in fact can mess up your model when spun.
  3. The round edge has way too many vertices for such simple object: Subdivision Surface modifier can handle smoothing the shape really well.
  4. It may be beneficial to use the Screw modifier instead of spin tool. This way you can tweak the shape of cross section to modify the bowl as a whole. When you’re happy with the shape, the modifier could be applied if some additions like handles are needed.

Here’s an example blend file to illustrate all of the above.
