Cannot modify an existing Design. Error : The design has been closed on the backend. Cannot perform any operations on it

[Abhijith022]

Hi Team, Good day!
I was trying out following script while I got the error: "The design has been closed on the backend. Cannot perform any operations on it"

Please let me know the issue

sk_rect=Sketch()
(sk_rect.box(Point2D([0,0],UNITS.m),Quantity(10,UNITS.m),Quantity(10,UNITS.m))
            .box(Point2D([0,0],UNITS.m),Quantity(5,UNITS.m),Quantity(5,UNITS.m))
)
design=modeler.create_design("Extruded box")
body1=design.extrude_sketch(f"Body_extruded",sk_rect, Quantity(5,units=UNITS.m))

Allcentre=[[8,8], [8,-8],[-8,-8]]
for centre in Allcentre:
    design.extrude_sketch(name="Check1",
                       sketch=sk_hole.circle(center=Point2D([centre[0]/2,centre[1]/2],UNITS.m),radius=Quantity(.5,UNITS.m)),
                       distance=Quantity(5,UNITS.m),
                       cut=True)

Hi @Abhijith022! For the purpose of trying to reproduce your issue... would you be able to answer the following questions?

1. What version of PyAnsys Geometry are you using? You can figure this out by running the following
   python -c 'from ansys.geometry.core import __version__; print(__version__)'
2. What product are you running PyAnsys Geometry against (Discovery, SpaceClaim, DMS, Geometry Service..)

Thank you in advance!

Hi Rob,
Python version: 3.12.7
PyAnsys Geometry version: 0.10.9

I am using modeler=launch_modeler(). I see Discovery starting up

Thanks

Okay gotcha - let me try to replicate it =)

Hi @Abhijith022 - so I ran your script (with some slight modifications). I am using Ansys Discovery 25R1 and PyAnsys Geometry 0.10.9

from pint import Quantity

from ansys.geometry.core import launch_modeler_with_discovery
from ansys.geometry.core.math import Point2D
from ansys.geometry.core.misc import UNITS
from ansys.geometry.core.sketch import Sketch

modeler = launch_modeler_with_discovery()

sk_rect=Sketch()
(sk_rect.box(Point2D([0,0],UNITS.m),Quantity(10,UNITS.m),Quantity(10,UNITS.m))
            .box(Point2D([0,0],UNITS.m),Quantity(5,UNITS.m),Quantity(5,UNITS.m))
)


design=modeler.create_design("Extruded box")
body1=design.extrude_sketch(f"Body_extruded",sk_rect, Quantity(5,units=UNITS.m))

Allcentre=[[8,8], [8,-8],[-8,-8]]
for centre in Allcentre:
    sk_hole=Sketch()
    design.extrude_sketch(name="Check1",
                       sketch=sk_hole.circle(center=Point2D([centre[0]/2,centre[1]/2],UNITS.m),radius=Quantity(.5,UNITS.m)),
                       distance=Quantity(5,UNITS.m),
                       cut=True)

design.plot()

This script ran just fine for me when installing ansys-geometry-core[graphics]==0.10.9. If you don't want the graphics part (i.e. design.plot() needs it), you can just uncomment that line and run it with your current environment. Hope this helps, let me know if you still hit issues.

Just so you know, I didn't do any critical changes... just redefined some missing variables. If you still get an error on your side please let me know. If everything works, I would kindly ask you to mark the previous message as an answer so that other users can benefit from it. Thanks!
