Multi-extrude in one part

Hello,

Does anybody know a simple way to create an extrusion on multiple lines
in Pro/E inside the same part?

I'm working on a steel construction of a total building. I have the
lines that represent the hart of the steel beams.

A single extrusion works fine on one line only, but the as soon as the
extrusion are intersecting, Pro/E refuses to create the geometry.

Creating all different parts is no solution, because I have over 250
elements.

Can anyone think of a solution?

Thanks for responses,
Pim Marsman.

Trying to do this with thin protrusions or surfaces bomb with error messages, like
multiple loops must all be closed. Doesn't look like either of these will work as
I thought they might. Don't see why you wouldn't be able to create an i-beam with
either thin protrusion or surface technique.

If they are all similarly shaped in cross section, couldn't you create a family of
parts, embodied in a table of variable parameters (like length, width, height)?
This should be an assembly, not a sketched feature. Even if it worked, it just
bogs sketcher to a standstill. It's not AutoCAD, just sketching draft geometry.
It's built on a variable solver which is calculating dimensions and contraints
from each piece of geometry to the existing geometry. That alone is a big job.
Complex sketches easily overwhelm sketcher, even if they don't completely fail.
