airfoil import and scale Doesn't work on linux

[warriorman8]

As described in the title and when attempting to run it says: <class 'AttributeError'>: 'PySide2.QtCore.QCoreApplication' object has no attribute 'activeWindow'

[galou]

The title doesn't mention any macro.

[warriorman8]

regardless it mentions a problem in line 38. I activate sketch editor, click the icon and it doesn't work because it is on linux.

[warriorman8]

the problem refers to airfoil import and scale

[warriorman8]

This fixed did not work at all, please actually test it on a linux distribution.

[jpretori]

I run Arch and am happy to help test. When I search the Addon manager for "airfoi" I get these results. Which of them are we talking about?

Thanks @warriorman8. Please will you attach the .dat file you use when encountering the problem?

EDIT: I tried with 2 airfoil files I found here, both give me error messages unlike what you're getting: https://tracfoil.com/airfoils/index.php

aerofoil.txt

OK I tried to import this.

I was unable to even see the file in the load dialog until I changed its extension to .dat. So I did that.

1. I renamed the file to aerofoil.dat so the dialog box could see it
2. Made the chord length 100
3. Left the radio button on DWire

I get this error message in the Report view:

10:29:17 /home/johan/.local/share/FreeCAD/Macro/AirfoilImport&Scale.FCMacro:89: DeprecationWarning: 'exec' will be removed in the future. Use 'exec' instead. self.dialog.exec_() 10:29:19 Error, not a valid .dat file

This is the same as I got for the other .dat files I tried.

So I fiddled around with the macro itself, and made it import the traceback module & print out more complete exception details. Here is the message it ended up giving:

10:49:02 Error, not a valid .dat file 10:49:54 (1)<class 'SyntaxError'>: '(' was never closed (AirfoilImport&_Scale.FCMacro, line 77) 10:50:16 Error, not a valid .dat file 10:50:16 Traceback (most recent call last): 10:50:16 File "/home/johan/.local/share/FreeCAD/Macro/AirfoilImport&_Scale.FCMacro", line 103, in proceed 10:50:16 importAirfoilDAT.insert(f1,"Unnamed") 10:50:16 File "/usr/lib/freecad/Mod/Draft/importAirfoilDAT.py", line 106, in insert 10:50:16 obj = process(filename) 10:50:16 ^^^^^^^^^^^^^^^^^ 10:50:16 File "/usr/lib/freecad/Mod/Draft/importAirfoilDAT.py", line 136, in process 10:50:16 afile = pythonopen(filename, 'r') 10:50:16 ^^^^^^^^^^ 10:50:16 NameError: name 'pythonopen' is not defined 10:50:16

Seems like the importAirfoilDAT module has some problem.

@galou could you please give some help at this point? Searching Github it seems like this is somehow part of Freecad? How do we proceed from here?

import and scale (second)

It's stated that the second item on the list is from the wiki and the third is from git. Someone should update the git version (@quick61) .

[galou]

The error mentioned by @jpretori was changed (fixed?) with https://github.com/FreeCAD/FreeCAD/commit/ff11cd25ee99b5e959616f3805f0d9bfd3a0be76.

I was able to import the file above but I have the impression that the "Chord Length" parameter doesn't do anything. I also get the error message "Error, not a valid .dat file" though.

[jpretori]

I fiddled with it some more, but got nowhere. I'm willing to help, but don't know what to do. So for now I'm going to leave it alone until someone suggest something specific that might be helpful :)
