Create a basic piping from zero

 
  • Hi PDMS Masters.
    I have a collection of bars and points with diameter that I stored in a database imported from Caesar II and wish to create a pipe from it, with a default spec.
    I just want a pipe with the correct diameter at the correct points, and I have all that info.
    How can I do that?
    I tried creating a pipe, a branch and then some attas at the points, but I dont see where I need to put the diameter.
    What are the required attributes to build a basic generic pipe?
    Thanks!!
