Help with featurescript subtraction

  I suspect that your issue is the queries that you're passing ito the boolean:

  "tools" : qCreatedBy(id + "extrude" + i), → All entities created by (id + "extrude" + i). Bodies, Faces, Verticies, Edges, etc. Note that I'd recommend changing this code to qCreatedBy(id + ("extrude" ~ i)). Id's can get brittle, and I've found that concatenated pattern to work well.

  "targets" : evaluateQuery(context, qOwnerBody(qUnion(faces))), —> This seems like a backwards way to get what you're looking for. Why not just pass the part in as a parameter?

  As a quick fix/test, I'd do the following:

  1. Filter your tools down so it's just getting bodies. You can do this by adding an EntityType.BODY and or BodyType.Solid to your query, or by wrapping an additional Entity/Body type filter around your tools query.
  2. Add debug entities for both your tools and targets. Are they showing up as you'd expect?

  I did the first thing, but it didn't fix it.

  What do you mean by a debug entity?

  I'd look into the featurescript classes at learn.onshape.com. I'd also look at how you're getting entities with qCreatedBy - when you type it out, tooltips pop up and could help you get the query you're actually looking for. addDebugEntities is a way of highlighting certain entities which is really helpful when debugging a feature (and occasionally, to make feature operation more intuitive to the user).

  Fixed it.

  Here's what I put for the Boolean

  opBoolean(context, id + "boolean1", {
  "tools" : qCreatedBy(id + ("extrude" ~ i), EntityType.BODY),
  "targets" : qOwnerBody(face),
  "operationType" : BooleanOperationType.SUBTRACTION
  });
