How to create a thickness dimension to a closed spline. Can it be offset somehow?

I have created a simple loft using a circle and closed spline. I would like the loft to have a wall thickness of about 3mm. Basically a vase with the circle being the base. I have tried offset, shell, remove face etc. with no success. Your guidance would be much appreciated. Thank you.

I bet it will shell at 1mm. The curvature of the spline is too tight for such a big offset.Senior Director, Technical Services, EMEAI5 -

"Show curvature" "Minimum radius" is your friend:
If you adjust the spline so that the minimum radius is greater than 3, you should be able to offset it by that much.6

Thank you S1mon- I'll endeavour to become more aquainted with minimum radius.
