Modeling a Square Tube in different ways to lear featurescript

I think is the best when you can get something done in more than one way and feature script allows that. I don't mean to find the easy way, I want to learn from it.
1 - Create 2 square sketchs, Extrude both, remove the smaller from the biggest with Boolean. That one was easy!
--> Create 2 Sketchs
2 - Create 2 square sketchs, extrude the region in between. Couldn't query this region
3 - Create a sketch, extrude as surface, Thicken the surfaces. Couldn't Extrude as surface
--> Create a Sketch
extrude(context, id + "extrude1", {
Can Someone show how to make options 2 and 3 possible?

--> Create 2 Sketchs
skRegularPolygon(sketch1, "polygon1", {
"center" : vector(0, 0) * inch,
"firstVertex" : vector(1/2,1/2) * mysize,
"sides" : 4
});
skRegularPolygon(sketch2, "polygon2", {
"center" : vector(0, 0) * inch,
"firstVertex" : vector(1/2,1/2) * (mysize - mythick),
"sides" : 4
});
--> Extrude Both
extrude(context, id + "extrude1", {

extrude(context, id + "extrude1", {
"entities" : qSketchRegion(id + "sketch1"),
"endBound" : BoundingType.BLIND,

extrude(context, id + "extrude2", {

3. - pass "surfaceEntities" : qCreatedBy(id + "sketch1", EntityType.EDGE) , no need for "entities" field to extrude.
We recommend using opExtrude in feature script instead of extrude for better performance.
2 - you nail it. I'm using opExtrude.
3 - using extrude because didn't found BodyType option in opExtrude.
extrude(context, id + "extrude1", { "bodyType": ToolBodyType.SURFACE, "surfaceEntities" : qCreatedBy(id + "sketch1", EntityType.EDGE), "endBound" : BoundingType.BLIND, "depth" : definition.myLength });Didn't work and I could'n find why, I still get EXTRUDE_INVALID_ENTITIES. But
extrude(context, id + "extrude1", { "bodyType": ToolBodyType.SURFACE, "surfaceEntities" : qCreatedBy(id + "sketch1", EntityType.FACE), "endBound" : BoundingType.BLIND, "depth" : definition.myLength });Worked but it forms an SOLID, not SURFACE Body, I debug the query and both are working.opExtrude doesn't need BodyType option. If you pass it edges in the "entities" field, it will make surfaces:

If you post the URL of your document here, we'll be happy to take a look at why that extrude() is failing.
here it is.

I did what I never saw in the documentation but I use ons sub-node of the LookupTable as valuewithunits, works as long as the entry has units in it.
You have it pinned down when you ask "Shouldn't this be 4 edges, not 8?" Due to the way our sketching system works, there are actually two sets of edges created when you sketch: the wire bodies that you directly create in your sketching operations, and the edges around the sketch regions that you create indirectly.
Long story short, the query that you want is:
qOwnedByBody(qBodyType(qCreatedBy(id + "sketch1", EntityType.BODY), BodyType.WIRE), EntityType.EDGE);
a.k.a. "All the edges of wire bodies created by the sketch operation"
edit1: I did this and it worked.
<div>function QSketchEdges(id is Id)</div><div>{</div><div> return qOwnedByBody(qBodyType(qCreatedBy(id, EntityType.BODY), BodyType.WIRE), EntityType.EDGE);</div><div>}</div>and used like that.
<br><div>opExtrude(context, id + "extrude1", { </div><div> "entities" : QSketchEdges(id + "sketch1"),</div><div> "direction" : evOwnerSketchPlane(context, {"entity" : qSketchRegion(id + "sketch1")}).normal,</div><div> "endBound" : BoundingType.BLIND,</div><div> "endDepth" : definition.myLength </div><div> });</div><p></p>A correction from my coworker: qBodyType actually happily filters entities based on the body type of their owner, so a simpler Query is:
Nice function!
