File? How do you produce the error? What version? Any extra WB since that seems no FreeCAD default error message?

[edwilliams16]

The error message is saying you are trying to do a Frenet attachment on a straight line. That can't be done because only curved lines have a well-defined normal direction.

How do I get extra info of this on a big file with a lot of other things inside? I would like to locate the Object/Feature/Sketch/Operation. Is it possible somehow?

Hi. The version of what you ask? The version of Freecad is 0.21.
I think I am using the following workbenches but may have some others that I am not aware of.
- Assembly4
- Part Design Workbench
- Sketches
- Fasteners Workbench

For the limited minds. This is the file.

See, I am not asking for you guys to "find the culprit" and fix it for me.

I am asking "HOW do you find/identify the culprit Object/Feature/Operation since the f* message is generic af?"

Provide your FULL version as asked in the red banner link.

Oh, awaiting help, but insult the helpers. How about to read the links in the read box and think about your behavior and how helping works, since we are no wizards with a glass orb.

How to avoid the error you ask, just do not make the error ....... what the f*ck there are people .......
