Hello realthunder, I've found a bug in your latest release:

I had made earlier some experimenting with the Path workbench, to produce Gcode for manufacturing some real parts. This was done with:

OS: Ubuntu 18.04.1 LTS
Version: 0.18.15363 (Git) AppImage
Build type: Release
Branch: master
Hash: 9be3e633328335f1172456f5857219b7a08c70a5
Python version: 3.6.7
Qt version: 5.6.2
Coin version: 4.0.0a
OCC version: 7.3.0

I didn't yet use the Gcode (with an Arduino Shield). But when I load the 2 files in your latest AppImage, it crashes hard

Can you please copy your FreeCAD version information ? (Help -> About FreeCAD -> copy to clipboard) .

Hello realthunder, I've found a bug in your latest release:

Thanks for reporting. It's been fixed. Please sync LinkStage3 and try again. I'll release a new image soon.

[Zolko]

One of those elementary question still remain unanswered - why the files are opened in the first place? I.e. you don't show a configuration text file to user, when you're reading configuration lines from it.

So, you are essentially complain about a UI problem? Too many tabs, is that it?

I didn't step in at that time, but I think that OakLD is right, and this could cause problems in the future: when you have hundreds of parts in an assembly, having hundreds of windows (tabs) opened will make it unusable. And when I close a window on a part that is included in an assembly, the part disappears from that assembly.

So while I understand that a part must be "open" for it to be included in an assembly, does it need a GUI window for that ? There is a command-line version of FreeCAD, how does it open a document if it has no GUI at all ?

I was not discarding his complain when I reply that. In fact, I was acknowledging this as a GUI problem, which I'll find a way to improve it in the future.

Please sync LinkStage3 and try again.

it compiles and runs now, but I have a problem with my PySide2 install, therefore many things don't work. I use your latest asm3 AppImage as standard now.

Hi All,

Testing (and trying to find my way round A3!) on OSX. I wanted to use a angle constraint to pivot the two plates around a hinge (indicated by the red line). See attached file.

The axial constraint works fine to link the two plates. The angle constraint gives an issue though, I just get the message "Failed to solve unnamed assembly: inconsistent constraints".

Did I miss some important part of the process?

Thanks!

Brutha

Update: actually I found that wrapping each part in an assembly, then combining those into another assembly seemed to work nicely!
