When you are working on a model, any vector artwork you create is drawn on the active vector layer.
Only one vector layer can be active at a time, although the artwork drawn across all visible vector layers is displayed, and you can have more than one layer selected.
To choose the active vector layer:
beside the
Vectors item in the Project Tree to display the vector-layer stack.
To select multiple vector layers:
beside the
Vectors item in the Project Tree to display the vector-layer stack.
