Need to add a few tests will mark it as ready once that's done

It looks like vars can never be undefined so this could be a const instead:

const vars: { 
exprs: Expr[];
pathIfPipe?: PathToNode
} = {
  exprs: []
}

Good catch, thank you! I made the change to assignments at 305c1bc and didn't change it!

[andrewvarga]

I tried it out, works well!

One thing I noticed is that while extruding cap is stable, I'm having a difficult time reconnecting to the engine when extruding a wall - either from the vercel preview link or running ZDS locally with your branch.

The render appears but then it goes away and can't reconnect. Is this supposed to work?

sketch001 = startSketchOn(XZ)
profile001 = startProfile(sketch001, at = [-2.23, 3.89])

  |> xLine(length = 5.58)
  |> yLine(length = 7, tag = $seg01)
  |> line(endAbsolute = [profileStartX(%), profileStartY(%)])
  |> close()
extrude001 = extrude(profile001, length = 5)
extrude002 = extrude(seg01, length = 3)

@andrewvarga Thanks! Yes I believe it's engine bug, let me move the conversation to the Slack thread and we should report this together https://kittycadworkspace.slack.com/archives/C04KFV6NKL0/p1770128241914559?thread_ts=1769709536.629029&cid=C04KFV6NKL0
