Hello,
This is not possible right now. If in ARCHICAD you create a closed planar polygon with the Morph tool, then it will automatically be covered with a face. To follow this behaviour, if you create a Morph from a closed planar curve from Grasshopper, ARCHICAD will generate a face covering it. I have let the designers know that this could be revised.
You can of course just unlock the element in ARCHICAD, and remove the face manually.
