Problem creating Pipe geom- Tutorial using Salome

Hi there,

I appreciate this problem may be extremely simple and thankyou in ADVANCE

I am following this tutorial:

www.caelinux.org/wiki/downloads/docs/Pipe2007/PipeGeom.htm

After drawing the path for the pipe, you have to explode it before extruding a circle face along it
creating a pipe. I have followed the tutorials meticulously, numerous times, but when it
comes to selecting the vertex in the explode task, I dont get the same vertex highlight in blue. If I continue anyway the pipe pipe cannot be created properly.

Frustrating as its such a small thing to be stuck on and extremely eager to continue! Suggestions will be greatly appreciated

Cheers

Danny
