splines and 3d

Now, I know I can't extrude a spline... to the best of my knowledge, but I have a drawing that I would like to make a 3d object of with as little fuss as possible. It is made up of splines. Any thoughts on how I can take this object and extude it?
Thanks!

Copy over your spline with arcs, join them and extrude the arcs? Sorry, I know it's a lot of fuss, but I can't think of any better way.
P.S., I can't tell what version of CAD you're using and haven't tried the spline idea in 2007 yet.

What exactly are you trying to do?

from memory there is a variable setting that says to create splines as poly lines, perhaps you can set this and re-open the drawing and hope it has changed and away you go. Other than that, approximating the spline by tracing it with a polyline would be the simplest answer.

Watch how many endpoints your pline has. The more points on the polyline the more little bitty surfaces you will have.

A closed spline extrudes, Acad 2006, you can also make a region of touching splines and extrude that.

You can also you use the express tools flatten command. That will make arcs, then just pedit and extrude.

at least since 2007 splines could be extruded...

You have always been able to extrude a closed spline or ellipse, as noted above. Acad 2007 allows open splines/ellipses to be extuded and then thickened with the thicken command to create a 3D solid.
