Arch CutPlane - Error: tuple index out of range

[wolfcastle]

Hello Experts,

I have a slight problem with Arch CutPlane, I just wasted 4 hours getting it to work, but to no avail.

In the attached drawing, when I select in the following order "axle" then "Rectangle001", and follow the instructions here https://www.freecadweb.org/wiki/Arch_CutPlane I get this error:

Traceback (most recent call last):
File "/usr/lib/freecad/Mod/Arch/ArchCutPlane.py", line 109, in previewCutVolume
cutVolume = ArchCommands.getCutVolume(FreeCADGui.Selection.getSelectionEx()[1].SubObjects[0], FreeCADGui.Selection.getSelectionEx()[0].Object.Shape)
IndexError: tuple index out of range
Running the Python command 'Arch_CutPlane' failed:
Traceback (most recent call last):
File "/usr/lib/freecad/Mod/Arch/ArchCutPlane.py", line 69, in Activated

self.previewCutVolume(self.combobox.currentIndex())

cutVolume = ArchCommands.getCutVolume(FreeCADGui.Selection.getSelectionEx()[1].SubObjects[0], FreeCADGui.Selection.getSelectionEx()[0].Object.Shape)


I really need this feature, any suggestions?

UPDATE: I tried installing FreeCAD on two more machines, one of them being a 32 bit ubuntu 17.04. The problem persists now on all three machines.

And here is my FreeCAD info:

OS: Ubuntu 16.10
Word size of OS: 64-bit

I can't reproduce your problem, so I don't have any suggestions on how to fix it. The file is attached, it works as expected for me using:

OS: Ubuntu 16.04.2 LTS
Word size of OS: 32-bit
Word size of FreeCAD: 32-bit
Version: 0.16.6710 (Git)
Build type: None

Dear bejant

it works as expected for me

So can I send my drawing to you, so you can make a CutPlane for me?

Seriously, it's not working even with just a solid cylinder and a rectangle. I guess I will have to make a new install of FreeCAD, I see you are using a 32 bit version, whereas I'm using a 64 bit version, something being "out of range" could be caused by differences in compiling for 64 bit. At least that's my best guess at the moment.

I can try, if you like.

Maybe someone with a 64 bit version of FreeCAD will try too and we can compare results to see if it is a problem on all 64 bit versions or maybe something happened to your installation.

FYI @wolfcastle opened issue #3082, once issue is diagnosed please notate the ticket. Thanks!

Please take a look how to report bugs to FC via the link in my signature

Thank you, maybe next time I have an urgent need for it, obviously unless it has been resolved in the mean time.

As I mentioned in my edit, I can now reproduce the issue on 3 different machines, two Ubuntu 16.04 64bit and one Ubuntu 17.01 32 bit

You're welcome, my offer is simply something to keep in mind but I'm sure other forum regulars will help if I am absent.

As I mentioned in my edit,

Oops, I missed the edit. I had a bunch of browser tabs open and left the computer several times without refreshing the pages after returning.

Works as expected on ubuntu 16.04 with FC 0.16 and 0.17

Try installing 0.17 on your PC, and see if it works.

I can reproduce a similar error by:
- select cutting object
- select face
- click "cut-plane" button
- click somewhere in the scene to delete selection
- press OK

Code: Select all

Traceback (most recent call last):
  File "/usr/lib/freecad-daily/Mod/Arch/ArchCutPlane.py", line 103, in accept
    FreeCADGui.doCommand("Arch.cutComponentwithPlane(FreeCADGui.Selection.getSelectionEx()[0],FreeCADGui.Selection.getSelectionEx()[1].SubObjects[0],"+ str(val) +")")
  File "<string>", line 1, in <module>
<type 'exceptions.IndexError'>: list index out of range

So simple do not change selection during this operation should do the job.

ps.: maybe writing a bug report would make sense.
