Currently running inventor 2013 premium still on the free trial until it runs out and i register it.
I am trying to create my own tube and pipe style for a 22mm copper heating pipe run.
I have been through and created the parts and successfully published them into a user contents library.
I start a new tube and pipe run in an assembly. then go manage>tube and pipe styles
I then hit 'New' i fuill out the details, select my pipe, bend and coupler...everything seems ok, i hit save.
it doesnt appear in the styles selection menu to the left (where it should and did on the tutorial) and whats more when i try and exit or do anything else the 'Save Edits?' warning comes up (clicking save doesnt help)
This is the second tube and piping run in this assy. but is a whole new run rather than route.
I had some similar issues when I was first learning to set up the Tube & Pipe module. I have attached a document that details some of these issues and what I did to fix (or work around) them. It sounds like the trouble you are experiencing is similar to what I described in part 1 of the document.
Hopefully this helps.
It sounds like you are having a different issue, so you really should have started a new thread. But check the filters in the selection dialog. You may have a filter that is excluding your copied pipe style.
