Hi. I'm having trouble getting the plugin to work with my model. I have a set of curves I want to join, but I'm not able to select the curves. I tested the install using the arc tool with success. In my model I created the "arcs" by stretching/scaling a circle. I believe I exploded the shape along the way. There must be something fundamental that I missing that is required for the plugin to work. Any thoughts? My file is attached.
