@martinsiegrist, fair enough. Right now eleFront uses pattern matching to search the layer table. Since “Layer 01” will match multiple layer names, multiple results will be returned. Aside from adding the option to reference full layer names only, one could add a filter on the results to drill down on what they are looking to reference. In the example below I used “Get Rhino Attributes” to return the full layer name and then use that to drill down on what to select.
Ultimately I would urge the use of key/value pairs on rhino objects to help with referencing and filtering or at the very least different layer names, but often enough you may have a file that comes from someone else that you need to work with and some downstream filtering often does the trick by adding an extra layer of control.
