Hi @wannastar,

Fast DDS Spy tool does not know any type but discovers them dynamically using dynamic types. That is, the ShapeType type you are looking at is not pre-loaded or pre-compiled by the tool, simply the Shapes Demo application announces its type so that other applications can discover it. In this way, the Spy discovers the ShapeType type and from there it can handle the data coming from this type.

I recommend you to go to this tutorial on how to configure and enable Dynamic Types in your Fast DDS application so Fast DDS Spy can discover it.
