Hi everyone,
first of all I'm pretty new to FreeCAD. I'am quite experienced in 3D modeling since im working maybe 80% of the time in my day job with 3D CAD programs.I figured, that FreeCAD suits me needs best for use in my free time. Lately I'm working on an assembly of a model steam engine.
But first of all this is my setup:
OS: Windows 10 Version 2009
Word size of FreeCAD: 64-bit
Version: 0.20.1.29410 (Git)
Build type: Release
Branch: releases/FreeCAD-0-20
Hash: f5d13554ecc7a456fb6e970568ae5c74ba727563
Python 3.8.10, Qt 5.15.2, Coin 4.0.1, Vtk 8.2.0, OCC 7.6.3
Locale: German/Germany (de_DE)
Installed mods:
* Assembly4 0.12.4
* fasteners 0.4.23
I work in the assembly 4 workbench. I create seperate files for every part. Then i have a file which is my assembly file. I use the import part command to import the parts in my assembly and position them relative to the parent assemlby. There was a I did this for all non-moving parts of the steam engine.
Until this point I worked in an older Version of FreeCAD. (0.19something). Then I updated to the Version You can see above. And updated all the add_ons.
Now i wanted to proceed connecting the moving parts. For example the crankshaft.
And here comes my problem:
Somehow, without me knowing where I possibly changed a setting or something, I get a FreeCAD warning, when trying to either:
-
"import part" as described after using the import part command or,
-
trying to use the command "edit the placement of a part"
which says: (see sequence at the end)
I tried everything which came up to my mind.
- trying to create a new assembly and creating links to the files(parts) I already modeled.
- copying the parts in a new file and recreating the link
but everytime I somehow copy that attachement extension and can't figure how to delete it or get rid of it.
What worked was: Creating a new file and creating new parts within. There I was able to constrain the parts like before but as soon as I try to import a part which somehow got that attachement extension I get that warning.
Does anyone know how i possibly can use my modeled parts without running in that problem? Or how I need to edit them?
Sequence as follows:
Thanks in advance.
Im looking foreward to your suggestions!

ouch ! Do you remember whether the previous version was 0.11.5 ? Unfortunately, it had this bug and corrupted all the files that were *created* with it. If you only manipulated with that version then there was no problem, but all parts and bodies created with that version are corrupt. I didn't find a solution to repair them, sorry.mech_eng92 wrote: ↑Mon Nov 14, 2022 6:54 pm Until this point I worked in an older Version of FreeCAD. (0.19something).

This bug is documented in the Assembly4 Read-Me:
If this is your case, I'm really sorry, you must re-create those parts.Important Note: version v0.11.5 had a hidden nasty bug that also corrupted the parts that were created with it. Unfortunately, these parts cannot be automatically fixed, they must be re-created. Only parts created with v0.11.5 are affected, not those that where merely used with it.

Re: Attachment extension
First of all thank you for your quick answer @Zolko!
Well my situation improved a little bit since I do know now that the problem wasn't necessarily my fault. The greatest part of finding the solution is understanding what the problem is...and the second time (modeling) is alwasys faster :
Thank you!
