And to show my appreciation to you, I'd like to show you the video I was able to create with your workbench:

I'm part of the team that develops the possible second Hungarian satellite, SMOG-1 and I created this demo video to show the build up of the device.
The animation was purely run by python script, including the Exploded Assembly functions.

Thanks!
Hi Therman
can you share to us your animation code
much appreciated - thanks!

Awesome Workbench!

But i could not find a way to export a video file from the animation. Is there a known way?

Edit:
Found a good solution. Downloaded OBS screen record tool. Unlocked drawing window and put it on my second monitor. Started the recording and afterwards started and ended recording from my first monitor.

Hi,

I have posted another thread regarding automatic exploded view and I was told thatFreecad has Workbench.
I guess you already know about the Paper I refer to, nbit still I would like to mention it still. What do uou think about this and is it possible to implement in Workbench?
See link to thread below.

Is there any written documentation beyond the examples?

Hi,
the AlignToEdge function does not work:
Running the Python command 'AlignToEdge' failed:
Traceback (most recent call last):
File "C: \ Users \ Administrator \ AppData \ Roaming \ FreeCAD \ Mod \ ExplodedAssembly \ EAInit.py", line 386, in Activated
va = (edgeA.Curve.EndPoint - edgeA.Curve.StartPoint) .normalize ()
'Part.Line' object has no attribute 'EndPoint'

Can you help me fix the code?

I suspect the objects you picked were not the type of objects the developer was expecting. As you found out, the code does not trap exceptions and provide useful messages as to what went wrong.

Exploded Assembly (EA) was written back when FreeCAD had limited or no Assembly tools, so it included a few basic tools of its own. Today I would suggest using one of the assembly workbenches to create your assembly and forego the EA tools. Once you have your assembly, you can use EA to tear it apart in an animated way.

Also note that you should create your explosion on a copy of your assembly. EA creates its own internal list of the starting locations of the objects it moves. if you apply EA to your main assembly file and then subsequently make changes to the assembly that relocates the base position of some objects, EA will be unaware and the animation will probably break.

I was not able to figure out how this works ... or if this is just broken. I tired several (every) possible way to select object, edge, trajectory ... Find enclosed a very simple example. Trying to modify the trajectory I get the following message:

Code: Select all

Running the Python command 'ModifyIndividualObjectTrajectory' failed:
Traceback (most recent call last):
  File "C:\Users\ADMIN\AppData\Roaming\FreeCAD\Mod\ExplodedAssembly\EAInit.py", line 140, in Activated
    ea.modifyIndividualObjectTrajectory()
  File "C:\Users\ADMIN\AppData\Roaming\FreeCAD\Mod\ExplodedAssembly\ExplodedAssembly.py", line 588, in modifyIndividualObjectTrajectory
    for i in range(len(sel_traj.names)):

'Part.Feature' object has no attribute 'names'
Any hints?

Thanks in advance! Mark

I tend to split this topic or move it completely to Help forum. What do you think?
