is there any software which can draw a 3D graph from 2D axisymmetric data

Tecplot?

do you mean, create an object of revolution?

Yes!

We have a tool. Komodo-REV. We are planing to move this into our Rhea-series tools. Komodo is a data digitization tool but has an object of revolution construction dialog. Komodo usage is pretty simple:

o load or paste bitmap

o locate xy corners of the plot

o define graph extents

o fill points (auto fill or single click)

o export points (if using as a digitizer)

o revolve points on either x or y axis (with offset) to create the STL

o export STL (ASCII) to file

Komodo also has a Laplacian smoother to help refine the lay-down of the points. Komodo is currently freeware; the help file is scant to non-existent. Send an email, and I will send a download link.

I have renamed the digitization tool to Rhea-Emulus. This can now be downloaded with an installer from our downloads page. I also posted a getting-started tutorial:

email if you have questions or problems

good luck
