thank you for quick response. i'm inside docker with ubuntu 22.04.3. the host os outside docker is ubuntu 20.04.6

[filaPro]

if you are not able to reproduce this, i can try to make minimal reproducible docker image

[jmwright]

It does not look like the polygon is closed, so the cause could be extruding an open/invalid sketch. If you remove the polygon call, and leave everything else, it works fine. One of the core devs who has worked more directly on the sketch feature can tell you more.

[filaPro]

thank you again for your response. i also investigated that the problem is about the polygon with zero area. what i expect is to get an exception, but not like dying os due to out of memory. for example this line cq.Worplane().sketch().polygon([(0,0),(1,1),(2,2)],mode="s").finalize().extrude(1) produces ValueError: Null TopoDS_Shape object, and it is fine.

[adam-urbanczyk]

Sometimes you'll get these kind of issues with invalid models. Here is a workaround:

import cadquery as cq
res = (
       cq.Workplane()
       .sketch()
       .push([(48.5800789794081,-3.3737790291878085)])
       .rect(3.0,87.6847679284009)
       .rect(3.0,88.65465934289723)
       .polygon([(0,0),(1,1),(2,2)],mode="s")
       .finalize()
       .extrude(1, clean=False)
)

Note that:

import OCP
OCP.BRepAlgoAPI.BRepAlgoAPI_Check(res.val().wrapped).IsValid()

results in

Out[8]: False

[filaPro]

Thank you, i didn't know about this clean=False. Believe the memory leak will be fixed in future releases of cadquery or occ.
