Sketch API seems to be sketchy

[neri-engineering]

I've tried this before and am trying again but each time, I feel like I'm just smacking my head against the wall.  The following code should be self-explanitory but I can't seem to get it to work.  Obviously it's supposed to draw a cone.  I specifically want to try to use Sketch; I know how to do this w/o Sketch API.

In particular I want to learn how to loft() with Sketch because then I can use the same Sketch object which is scaled and moved.

import cadquery as cq

sketch1 = cq.Sketch().circle(1)

sketch2 = cq.Sketch().circle(0.5)

result = cq.Workplane("XY")

result = result.placeSketch(sketch1)

result = result.workplane(offset= 5)

result = result.placeSketch(sketch2)

result = result.loft(combine= True)

There are docs for this: https://cadquery.readthedocs.io/en/latest/sketch.html#lofting-between-two-sketches

You need to use a single placeSketch call:

sketch1 = cq.Sketch().circle(1)
sketch2 = cq.Sketch().circle(0.5)

result =(

    cq.Workplane("XY")
    .placeSketch(sketch1, sketch2.moved(z=5))
    .loft(combine= True)

)
