This gets sort of complicated until you know your way around a CR2 file, but there is no need to use PHI Builder if it is a add-on for an existing figure. The way I did it was to pick a sister part and do a global search and replcae on the name with the new part name, then drag all the newely renamed parts into anoother copy of the same CR2. There are 5 places that must be moved, the part list at the very top, the detailed part list in the second section (where the actual bending info lives), the references to it in the parent for this part, and two more in the last section, the first is the parent-child list, the second is the weld list. After doing that, assuming the very first mention calls you added geometry correctly, you should be able to open the figure, and work with the joint editor to get the correct centers and bending settings. Can be done, maybe a little complicated, though! Don't forget all the regular rules, like childeren can't have any ajoining mesh if you want to weld the seam, I don't know how PhilC does that, either!
