asm4 Tuto2 crashes

Post by nic »

edit: duplicate of https://forum.freecadweb.org/viewtopic.php?f=3&t=42750

Hi there,

Freecad 0.19, asm4 up to date (see complete details below).

I'm currently training on Asm4 assembly, more precisely doing the tutorial#2 https://github.com/Zolko-123/FreeCAD_As ... TORIAL2.md.

Everything was fine up to defining LCS_pivot in the Arm part. FC silently crashes when I create the LCS_pivot. It doesn't crash if I do not set the X-offset.


Here is the full trace when FC is fired from the terminal:

To understand where is my error, I tried to download the final assembly from Zolko's tutorial https://github.com/Zolko-123/FreeCAD_As ... uto2.FCStd, but FC will never open it.

Code: Select all

Traceback (most recent call last):
  File "<string>", line 1, in <module>
<class 'OSError'>: Invalid project file /home/nic/Téléchargements/asm_tuto2.FCStd: basic_ios::clear: iostream error
I'm a bit lost here... help welcome.

huh, what's that version of FreeCAD ? I downloaded your model and it opens fine. Can you try with the pre-release AppImage build from FreeCAD instead of the daily build by Ubuntu ? This is what I (and many people I believe) use:

Hello Zolko,

thanks for answering. Well, The model I attached to my first post is also opening fine with daily. I provided it just for seek of completeness. From this model, when I create the "LCS_pivot", FC crashes...

The version I usually use is the daily version from ubuntu PPA. I tried the appimage as proposed, but same result : when I create the LCS_pivo based on arm LCS_0002 with R_disk offset, FC crashes.

Trying to open "asm_tuto2.FCStd" from ytou github page doesn't work either:

OK, so both appimage and daily is able to reproduce the bug. There is a same topic in parallel. So let continue on the following:
