Default Axisymmetric extrusion

Hi!

I have a 2d profile in the XY plan and I would like to have it extruded in axisymmetry, with Y being the radius.

I know the 2d3d function can do it, but it does it with the X direction for the radius, how can I change it?

Thanks!

My guess - Perform the operation with CSYS set to a properly aligned cylindrical coordinate system?

Thank you, but I tried.

After creating the geometry, I created a new coordinate system, performing some rotation, and I activated this new coordinate system.

Then I used the 2d3d function.

It did exactly the same as before, just as if the old coordinate system was still active.

It seems that the 2d3d function didn't operate in the new coordinate system.

I am so desperate...

type help vcex, one of the options is which system you want to use

You should take James' advice.

I never use the 2d3d functions. I do all my extrusions using vcex. I'm pretty sure at some point I've done axi-symmetric extrusion with vcex. The trick is to use a cylindrical coordinate system.
