- Helping a viewer with his project to animated a digger arm using a kinematic chain like animation. We now look at the final video in which we program a simple gui in python with a number of sliders to control the movement.
This is the final part of 3 videos relating to the task.

Excellent 3-part series of videos. Thank you.
I am looking to do some more longer videos but I am not sure how the community like these delivered. If they should be all together or seperated out into smaller shorter videos. Trouble is I don't have enough subscribers yet to be allowed to post a poll. Can I ask for your view? Thank you. And thanks again for the comment and support.
Nice! That works really well I'm surprised how compact the code is!
I'm wondering the effects if you add the same slider increment/decrement to the opposite 2 parts as well, to keep the motion relative to the section being moved, so it behaves more like a real hydraulic arm if you were to move a single control.
I will be having a go at that when i get some free time, now you have made the basis for it.
Thanks again : )
Glad you like. Yes please have a go and let me know how you get on.
Does A2Plus work on the latest V0.19? I have imported the files together and constrained them but they do not move.
That's the version I am using. Check to see if you have a part that is fixed? If not then this would be your issue, you require a fixed part to allow for constraint.
When i try it a message keeps coming up in the report view stating "21:47:53 AttributeError: 'NoneType' object has no attribute 'Placement'
Hello, I've never used python within FreeCad. At 1:57 you jump to a scripting environment. I assume this is the macro editor. I tried to copy what you did, but got an error "GitPython not installe! Cannot retrieve macros from git". You mentioned that PyQT is included with FreeCAD. I have v.19. Do I need to do something to enable PyQT?
I have never come across this message before. The editor in question is on the macro menu, macros... Then add new macro. You will then have a macro window. I did some searching and found this link where a few people are having similar problems which may help you forum.freecadweb.org/viewtopic.php?t=45592&start=10
