These seems to be the current program limitations. Perhaps you could provide some details (pictures, screenshots, drawings etc) as to how they are supposed to work so that we could improve the program in future.

Mike,
I'm getting the same result. This is a big problem. I need to connect supports to elbows and the stanchions won't connect. I have numerus dummy legs and the resulting ISO shows as open ended lengths of pipe.
Is it possible to edit a support catalog and make a copy of dummy leg, put a plate at the end of pipe, and use a correct SKEY for this type of support...
I think that SKEY is almost similar to Welded Sanction SKEY....
what your after is not a 'dummy leg', it is a 'duck foot'
I create a 'simple pipe support' and attach it to the node at the top of the elbow,
SKEY=DUCK,TYPE=SUPPORT
For the model i make the geometry for the leg and base plate with basic 3d autocad objects then attach them to the simple ring i attached to the elbow.
Works perfectly.....except for a bug in plant3d that puts the iso symbol in upside down (refer thread in link).

hope this helps, or that someone has a fix for the 'upsidedown duckfoot bug'
Cheers

We came up with a similar work around. I created a duplicate part family using elbolets since they have the correct connections to elbows. I renamed the descriptions and changed the iso symbol and type. In the model we just have AutoCAD geometry overtop of the elbolet. It works, but we have the same problem with the symbol coming in upside down on the iso.
OK so here we are 1 1/2 years later.
Now Im using plant3d 2012.
Im back onto the plant side of a project and need to add a few duckfoot supports to elbows (stanchion supports / dummy legs supports)
It looks like this issue hasnt been fixed.
In this case, I have the stanchion geometry as autocad solids.
I use the "convert supports" tool from the pipe supports panel of the home ribbon.
objects seem to convert ok...
add type=support; skey=duck
run iso and guess what....duckfoot is shown in wrong orientation.
hmmm...
apparently the way the pipe was routed controls this.
when the pipe is routed from the bottom of the vertical leg down to the horizontal pipe, the support will have its rotation plane horizontal....this gives the incorrect orientation of the support symbol on the iso
when the pipe is routed from the horizontal up to the vertical, the support will have its rotation plane vertical...giving the correct symbol.
