How to Query all Surface Bodies

Hi All,
I've got a problem where to create a reusable part, I need to combine all surface bodies in a document into a composite part. I'm struggling with the correct query. I've tried the following:
selectedBodies = qBodyType(qEverything(EntityType.BODY), BodyType.SHEET);
This gives the error "Cannot create a composite part containing a plane" So I tried to remove planes with qGeometry:
selectedBodies = qSubtraction(selectedBodies, qGeometry(selectedBodies, GeometryType.PLANE));
But this gives the same error. All of the surfaces I want to join are coplanar, but I assume this error concers reference planes.
The queries are being used as follows:
opCreateCompositePart(context, compositePartId, {
"bodies" : selectedBodies,
"closed" : false
});
"bodies" : selectedBodies,
"closed" : false
});
The equivalent for compositing all solid bodies works just fine.
selectedBodies = qAllModifiableSolidBodies();
What's the correct query to use here?
As an extension, I'd like to modify the standard 'wrap' feature so I can select this composite surface in a dialog box, and have the wrap feature apply to all faces of this composite body. Is there a way to do that?
Cheers,
Alex

@_anton beat me to it. You can also put it in your own function so you don't have to do that again .export function qAllSurfaces() { const allBodies = qEverything(EntityType.BODY); var surfaces = qBodyType(allBodies, BodyType.SHEET); surfaces = qSubtraction(surfaces, qConstructionFilter(surfaces, ConstructionObject.YES)); surfaces = qSubtraction(surfaces, qSketchFilter(surfaces, SketchObject.YES)); return surfaces; }
To modify the Wrap feature, copy it from the Onshape Standard Library, then make the modification you need from your copied document.
Note that wrap does not wrap to non cylindrical or planar faces.

You will need to modify the target input to something like this:annotation { "Name" : "Target", "Filter" : BodyType.COMPOSITE, "MaxNumberOfPicks" : 1 } definition.destination is Query;
Then, to get all of the faces out of the composite:const faces = qOwnedByBody(definition.destination, EntityType.FACE);
