startTracking with sweep

I am trying to do a tracking query on a sweep to get a face to put into opReplaceFace.
However, it resolves to nothing.
Here is my code:
However, it resolves to nothing.
Here is my code:
// Sketch
var sketch = newSketchOnPlane(context, id + "sketch", {
"sketchPlane" : skPlane
});
skLineSegment(sketch, "face1Line", {
"start" : vector(0, 0) * inch,
"end" : face1Point
});
skLineSegment(sketch, "face2Line", {
"start" : vector(0, 0) * inch,
"end" : face2Point
});
skArc(sketch, "arc", {
"start" : face1Point,
"mid" : normalize(face1SkDir + face2SkDir) * dist * (shape == FilletShape.CONVEX ? 1.15 : 0.75),
"end" : face2Point
});
skSolve(sketch);
toDelete[] = append(toDelete[], qCreatedBy(id + "sketch"));
// Weld Faces
var weldFace1 = qEntityFilter(startTracking(context, id + "sketch", "face1Line"), EntityType.FACE);
var weldFace2 = qEntityFilter(startTracking(context, id + "sketch", "face2Line"), EntityType.FACE);
// Sketch face
var sketchFace = qCreatedBy(id + "sketch", EntityType.FACE);
var sweepDef = {
"profiles" : sketchFace,
"path" : qClosestTo(qEdgeAdjacent(face1, EntityType.EDGE), distResult.sides[0].point),
"lockFaces" : face1
};
opSweep(context, id + "sweep", sweepDef);
debug(context, weldFace1); // Resolves to nothing :(0

tracking swept faces requires secondaryQuery of the corresponding path edge . Please see<div>function sweptfaceTrackingQuery(context is Context, sketchId is Id, sketchEntityId is string, path is Query) returns Query {</div><div> const sketchQuery = sketchEntityQuery(sketchId, undefined, sketchEntityId); <span style="background-color: transparent; color: inherit; font-size: inherit;"><font face="Flama, sans-serif"> const trackingQ = startTracking(context, {</font> </span><span style="background-color: transparent; color: inherit; font-size: inherit; font-family: Flama, sans-serif;"> 'subquery' : qUnion([sketchQuery, makeQuery(sketchId, "IMPRINT", undefined, {"derivedFrom" : sketchQuery})]), </span><span style="background-color: transparent; color: inherit; font-size: inherit; font-family: Flama, sans-serif;"> 'secondarySubquery' : path </span><span style="background-color: transparent; color: inherit; font-size: inherit; font-family: Flama, sans-serif;"> }); </span><span style="background-color: transparent; color: inherit; font-size: inherit; font-family: Flama, sans-serif;"> return qEntityFilter(trackingQ, EntityType.FACE);</span></div><div>}</div>

Yes, makeQuery(sketchId, "IMPRINT", undefined, { "derivedFrom" : sketchQuery }) resolves to the edge of sketch face corresponding to the sketch curve of sketchQuery5

If you have a query for the selection, you can just call `startTracking` directly, with that query as the "subquery" and the path as the "secondarySubquery".Jake Rosenfeld - Modeling Team5

Is this part of the function the edge of the sketch face?

How would I get the sketch id from a user's selection?
Or can't I do that?

What I was wanting was to allow sketch edge selection for my shaped flange feature

Are you sweeping the sketch region and trying to track one of the side faces, or sweeping sketch edge itself into a surface? If you're sweeping the sketch edge, you should be able to just do:
startTracking(context, { "subquery" : definition.edgeToSweep, "secondarySubquery" : pathEdge });
If you are sweeping a region into a solid, and trying to track one of the edges by user selection, it'll require some creativity. Sketch edges are actually independent wire bodies which sit on top of the sketch regions. Sketch regions have their own bounding edges, which are not topologically associated with the sketch edges. If your sketch is simple, though, it should not be too hard to find the correct sketch region edge to track, based off of a sketch edge selection.
Here is a document with an example of how to do both of the above things:

I am wanting to get the sketch face adjacent to the edge so I can do an opExtractSurface on it.
