[@gregwoolley]

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.

Does A2Plus work on the latest V0.19? I have imported the files together and constrained them but they do not move.

[@MangoJellySolutions]

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.

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.

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?

[@MangoJellySolutions]

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
