The “Splice plate” component requires separate member ends for its correct definition.
If the member is separated by a node of the “Standard” type, these two member ends should not be defined as “Continuous” in the “Members” tab of the add-on, otherwise the “Splice plate” component will not recognize the second connected member. The correct procedure is to set the type to “Member end”
This type of joint cannot be defined at a node of the “On Member” type (blue nodes), because this node type does not divide or separate the member. As a result, the “Splice Plate” component does not recognize the second connected member.
