For those of you that did not make it to Autodesk University, you may want to check out the following.
James Wedding has posted in the Discussion Groups the 17 page handout (.PDF) from his AU class titled "House of Style". It is a very good source of information pertaining to styles. The last page alone, which indicates where certain items in a typical profile (with pipes) are controlled from, is worth the effort to locate and download this document.
The title of this post is linked to the document. Once open File > Saveas to save it to your system.
Thanks again James for making everyone better.
