Here is an example of how you can use it:

opExtractSurface(context, id + "extractFace", {
                            "faces" : yourQueryHere,
                            "offset" : 0 * inch });

qThisSide = qCreatedBy(id + "extractFace", EntityType.FACE);

And here is some more info about it:

opExtractSurface (context is Context, id is Id, definition is map)

For Onshape internal use.

This function takes a list of faces and creates one or more surfaces from those faces. The source faces and body are not affected.

PARAMETER INFO

definition is map

- faces is Query
List of faces to be converted. If tangentPropagation is true, these are the seed faces.

- tangentPropagation is boolean   optional
Whether additional faces should be added to the selection by tangent propagation

- offset is ValueWithUnits   optional
Offset extracted surface faces by this distance along normal

- useFacesAroundToTrimOffset is boolean   optional
Use surrounding faces extensions to trim offset. Default true.

- redundancyType is ExtractSurfaceRedundancyType   optional

Controls the culling of redundant geometry on the result body, such as tangent edges and vertices. ALLOW_REDUNDANCY does not delete any redundant geometry. REMOVE_ADDED_REDUNDANCY removes redundancy created by this operation. REMOVE_ALL_REDUNDANCY removes all redundant edges and vertices. REMOVE_ADDED_REDUNDANCY is the default.

I didn't realize this had built in tangent propagation. Thanks, Michael!
