Intermediate path segments not being rendered until `close` call

[vrzh]

This is probably more of a question, but also maybe a bug.

I really like the "automatic reload and preview" inside CQ-Editor.

I am trying to build up a complicated path using many lineTo calls, and want to have a preview as I am in the middle of this. However, in the CQ-Editor preview window, I don't see the entire path (only the last segment).

If I want to see the path so far, I need to call close at the end, and then it renders. But, I am not finished with the path yet and so don't want to close it.

This seems not related to CQ-Editor itself, because if you generate an SVG output for attached example, you get the same effect.

I am using CadQuery and CQ-Editor via pip.

import cadquery as cq

# without the "close", only the last segment "lineTo(2,1)" is shown
result = cq.Workplane("XY").lineTo(1,2).lineTo(3,3).lineTo(2,1)

# with the "close", all segments are shown
# result = cq.Workplane("XY").lineTo(1,2).lineTo(3,3).lineTo(2,1).close()

with open('t.svg', 'w') as f:
    f.write(result.toSvg())

show_object(result)

Call consolidateWires() to render the intermediate result.

wi0 = result.consolidateWires()
show_object(wi0)

If you are working with Sketch, you can view the intermediate result like this.:

import cadquery as cq

s0 = (
    cq.Sketch()
    .segment((0, 0), (1, 2))
    .segment((3, 3))
    .segment((2, 1))
    #.close()
    #.assemble()
)

show_object(s0)

So this is not a bug. For Workplane only top of the stack is displayed.

Ahh, yes. That makes sense. Thank you.

Perfect, I will use this. Thank you.
