I am trying to create compatibility properties for nodes using the API. I am not sure of how to use IRobotNodeCompatibilityDef. I am able to add the label and define its data but how do you use the  IRobotNodeCompatibilityDef methods to define master and compatibility nodes? Can you please provide a short example?

[#2]

by CompatibilityDef you can only get \ check compatibility created on model 

Dim VLabel As RobotLabel
Dim VData As RobotNodeCompatibilityData
Dim Vdef As RobotNodeCompatibilityDef

'defining and assigning compatibility

Set VLabel = Robapp.Project.Structure.Labels.Create(I_LT_NODE_COMPATIBILITY, "comp")
Set VData = VLabel.Data
VData.UZ = True
Robapp.Project.Structure.Labels.Store VLabel

master_node_number=123

dim Bars as String

Bars = "3 4 5" 'bars list to which "slave" node will ve assigned 

Robapp.Project.Structure.Nodes.CompatibleNodes.Set master_node_number, Bars, "comp"

' checking compatibility defined on structure
Set Vdef = Robapp.Project.Structure.Nodes.CompatibleNodes.Get(1)
aaa = Vdef.LabelName  'checking compatibility name \ label used in this compatibility

bbb = Vdef.Bars 'bars list 
ccc = Vdef.Main  'checking compatibility main node number
ddd = Vdef.Compatible ' checking compatible node number

Why is it nessicary to have a bars list. What if the nodes i want to "couple" are connected to shell/area elements? Or no elements at all?

Even in Robot itself it is not intended to create compatibility between FEs. If you know the trick you can do it.

You can define compatibility between FEs node and bar it the way that main node will belong to FEs and slave node to selected bar(s)
