Button mapping - how to get a fitting made available in Revit Autoroute

[julielfifield]

I am trying to get a drop check elbow to show up as an option in the Route & Fill panel in Revit, but have not been successful.

I thought it was a button code or button mapping issue, & have tried several options, but can't get it to work.

Attached pdf shows the dropcheck button properties & button mapping for the service. Can anyone see what I am doing wrong?

From my LIMITED understanding, button mapping only plays a role in Revit when you are using Design to Fabrication to convert family content into Fabrication parts.

Route and fill works a little differently.....As i understand it, the parts available for route and fill are determined by joint connectivity. So it looks at the connectors on the ends of the parts and attempts to think through possible solutions within those constraints.....You will need to investigate which connectors the drop cheek wants to have and look at the connectivity in the connectors database to find out why this isn't working.
