AMEP NOOB: I need to add an eigth inch weld gap at each connection. I have searched forums, the 3 1/2" thick manual and I am coming up "0". Can some one please lay some wisdom apon me in how to do this?

It is a bit of a workaround that involves editing the xml files for the parts catalogs. You need to put in a negative 1/16” offset in the CEL1 and CEL2 (connection engagement length) fields so that flanges actually will have a 1/8” gap in between themselves, faking in a weld or gasket. It will be tedious to edit every one of the flange xml files to put in the CEL values. There is no built-in method to add gaskets, though it would be a great feature.

Ok, that sucked. But I did find that you actually have to put a -0.125 on each connection point and they over lap each other. I just hope I didn't mess nothing up. I waas batching it and there was a LOT of entries. But, they look pretty cool so far.
If you are trying to render the weld gap, then all may need is to toss in a thin solid disc and assign a material. If the goal was to just have and schedule dimensionally accurate pipe lengths, the the xml suggestion would be all you need. Often times the gap is too small to see on a plan view drawing, so the gap is drowned out. When we see support cases, it's just the schedules that people are more concerned with. Gaskets are another issue. Their thickness can add up quickly and make a pipe system off by a inch or more. It sounds as though you are interested in rendering. Maybe the solids suggestion is all that is needed to tweak the image?
the reason is, my welders get confused if they can't see the gap and I get tired off adjusting the pipe lengths to get the gap. I prefer the click click drop done thing, that I convinsed my employer was the reason I wanted MEP instead of vanilla AutoCAD.
Once the XML files for the content is adjusted, then it will be permanent. Any new pipe in drawings will be click click done. The Gap will be there, it simply will not have any meat between the gap.
Another method would be to create a parametric coupling that is 1/8 long that has a butt weld connectin on either end. Then in your pipe routing preferences, you would change your connector from <butt welded> to your new parametric coupling. This would allow you to schedule your welds and count/number them easily. If your gap was to change from 1/8 to something else for whatever reason, your coupling is parametric and could easily be changed once and in one location vs going back and rediting all of the xml files for every fitting.
Just a thought on an alternate way of doing it.
