Referencing a line from a sketch

I just started using FeatureScript.
I am trying to create a revolve part by using a line from a sketch as my revolution axis.
How can I reference it? I tried to create a variable but no success.
Here is the code:

        var sketch2 = newSketch(context, id + "sketch2", {

                "sketchPlane" : definition.sPlane

        });

        

       skLineSegment(sketch2, "line3", {

                "start" : vector(0, 0) * meter,

                "end" : vector(0 ,0.1 ) * meter

        });

        

        skSolve(sketch2);

        

        var section= qSketchRegion(id + "sketch1");

        

        opRevolve(context, id + "revolve1", {

                "entities" : section,

                "axis" : line(vector(0, 0, 0) * meter, vector(0, 0, 0.1)*meter),

                "angleForward" : 360 * degree

        });

The problem is it only works if the selected plan is Right or Front. I would like to use the line created in sketch2.

Thank you

If I try to use: qCreatedBy(id + "sketch2",EntityType.EDGE) for the axis,I get an error:

@opRevolve: Line should have an origin.

By hovering over the opRevolve function call (or looking up the opRevolve docs), we can see that "axis" needs to be of type Line (a data structure with an origin and a direction). qCreatedBy returns a Query (a specification which finds the entity or entities you want in the current Context), but not a Line.

In FeatureScript, the way to get information (like the position or direction) from the geometry you query is with evaluate functions. In your case, you could use either evLine or evAxis:

qCreatedBy(id + "sketch2",EntityType.EDGE)
});
opRevolve(context, id + "revolve1", {
        "entities" : section,
        "axis" : revolveAxis,
        "angleForward" : 360 * degree
});
const revolveAxis is Line = evAxis(context, {
        "axis" : 

This should be a useful/common pattern in FS. You can see another example with more explanation on this step of the slot tutorial.

Great, thank you
I definitely need to spend more time reading the doc.
