Default DesignLine settings question...

[mroble]

So, my current workflow, is in Revit, I'll route piping using default Revit piping, strictly for routing concept.

As the project advances and more detail is involved, I'll grab my piping, select "Design to Fabrication" and apply my service, and all my Revit piping becomes Mechanical Fabrication Piping. And at this point, I start fine-tuning the piping with "real" stuff.

What I'm trying to find, is where in the "Design to Fabrication" step is my ability to set something for a default?

For instance, right now, I draw this Revit piping as buttweld, then when it advances to the next step, I grab it, convert it to Fabrication, and everywhere I have a Revit tee, it becomes a Weldolet after conversion, and not a buttweld tee.

My Buttweld Tee button is set for "Branch-90" and my Weldolet is set for "StabInSocket". 

I'm looking at the button mapping in the service, but I'm trying to decipher what, exactly, it's doing.

Anyone have any good resource for button mapping?

This is one of those questions that doesn't have a quick fix. 

Autodesk University - The magic of button mapping. 

The above provides good insight. Also, note that in Revit the button order works as a hierarchy to what fitting etc. will be added.

That link didn't technically "solve" my issue, but it WAS valuable information to get me where I needed to get.

Problem is, I don't use CADMEP for "production", I'm using Revit, and using Fabrication, and CADMEP is merely my platform to customize our services in Revit.

Workflow:

1. I route all piping in my Revit model using default Revit Pipe Types, just to get routings approved

2. At a later date, when the design gets more detailed, I grab all my Revit piping, click Design to Fabrication, select the service, boom, it all changes to fabrication, and then I start getting into the nuts and bolts of piping.

What I was running into was that my Tee was set for Branch-90, and a Weld-olet was set for StabInSocket. For some reason, the Design to Fabrication was ignoring Branch-90 (Tee) and going straight for StabInSocket (WOL) and I couldn't figure out what made it choose.

I created a new Button, Branch-90, and in the rules, I set it to be the substitute for StabInSocket. Works, remains to be seen if that's the recommended approach, but it works.
