qSubtraction part edges vs sketch edges?

MichaelPascoe

I'm trying to preform a qSubtraction by subtracting the edges of a face and desired excluded edges. The subtraction works when both selections are on a part, but it doesn't work when the selection is a sketch face and a sketch edge belonging to the sketch face.

How would I preform a qSubtraction between the edges of a selected sketch face, and one of the edges selected on the same face?

Here is the code for the edges:

annotation { "Name" : "Path faces", "Filter" : EntityType.FACE }
        definition.face is Query;

        annotation { "Name" : "Exclude edges" }
        definition.excludeEdges is boolean;

        if (definition.excludeEdges == true)
        {
            annotation { "Name" : "Edges of path to exclude", "Filter" : EntityType.EDGE }
            definition.excludedEdges is Query;
        }

var loopedEdges = qSubtraction( qAdjacent(pathFaces[count], AdjacencyType.EDGE, EntityType.EDGE), definition.excludedEdges ); debug(context, loopedEdges, DebugColor.GREEN);

The sketch edges rendered on the screen are not adjacent to the sketch face. They belong to different bodies. You could use

var trackingQs = [];
for (var edge in evaluateQuery(context, definition.excludedEdges))
{
    const edgeTracking = startTracking(context, {"subquery" : edge, "lastOperationId": lastModifyingOperationId(context, edge)});
    trackingQs = append(trackingQs, edgeTracking);
}
const remainingFaceEdges = qSubtraction(qAdjacent..., qUnion(trackingQs));

Thanks for the quick response, I will try this.

This worked great! I would not have figured that one out.

 It is unfortunately rather obscure, very much informed by how we handle sketch geometry. startTracking is a useful mechanism for linking input geometry with results of operations.
