Assembly4: XLink absolute filepath problem

[FCuser2019]

Hi, I tried the tutorial https://github.com/Zolko-123/FreeCAD_As ... TORIAL1.md, I saved my files asm_tuto1.FCStd, axis.FCStd, bearing.FCStd in a directory I called "Tut1", everything works.
However, if I rename the directory with a different name, and try to open the file asm_tuto1.FCStd again, the assembly is not displayed and I get the following error messages:

Code: Select all

I downloaded all the files from https://github.com/Zolko-123/FreeCAD_As ... 4_Example2, I put them in a directory I called "Ex2", if I open the file asm_V4.FCStd the assembly is displayed correctly. If I rename the "Ex2" directory and open the file asm_V4.FCStd again, it is displayed without any problems.

This seems to be an absolute filepath problem in the links to objects.

Inside the Document.xml file of my asm_tuto1.FCStd I've seen that all XLinks have the absolute filepath:
<XLink file="/home/test/Documenti/FreeCAD/Forum/Assemly4/Tutorials/Tut1/bearing.FCStd"... />
<XLink file="/home/test/Documenti/FreeCAD/Forum/Assemly4/Tutorials/Tut1/axis.FCStd"... />

instead in Document.xml of asm_V4.FCStd all XLinks have the relative filepath:
<XLink file="Crankshaft.FCStd"... />
<XLink file="Cylindre.FCStd"... />
<XLink file="Bielle/asm_Bielle.fcstd" ... />
<XLink file="Piston/Piston.FCStd" ... />

Is there a way to tell Assembly4 to use the relative filepath when creating an assembly?

Thank you in advance for your help.

Please edit your previous post and put the log output in code tags </>. That makes your post easier to read because it is easier to distinguish between system output and your text.

ah yeah, you're right. I hadn't seen that, I'll have to investigate. realthunder, any ideas ? Is there a way to specify relative and absolute paths for App::Links ?

So, the difference comes from between FreeCAD-asm3 and FreeCAD-0.19-pre. I did the exact same thing in both, and -asm3 gives relative paths while 0.19-pre gives absolute paths:

• create 3 new documents
• save them as asm, part1, part2, in the same directory
• close them
• re-open them
• create a link (not Assembly4 link, a pure App::Link) in asm
• assign the linked part as part1
• create a link in asm
• assign the linked part as part2
• save

then when I rename the directory, -asm3 finds the links again while 0.19-pre looses them.

?

realthunder, did you modify the paths behaviour between -asm3 and 0.19-pre ?

EDIT: duplicate message

Thanks for reporting. That's a serious problem. Yes, something wrong when merging this part. I'll fix it soon.

Zolko, thanks for your quick investigation.
So let's wait for good news from realthunder.

Sorry to bother you but are there any news on this front?

It got stuck in one of my feature branch. I have just split it out and submitted the PR here.
