Sketcher as kinetic amination, ruled by GUI

[doul]

hello !

Just an other use of sketcher making kinetics animation, ruled with a GUI slider.

I start from https://wiki.freecadweb.org/PySide_Inte ... xamples/fr

Howto

- open FCStd file
- enter stekcher, edit sketch
- in python console type : execfile("/home/doul/menu2.py") <with your own file path>
- slide the slider !

Cant test right now but shouldnt the sketch be fully constrained? In the screenshot it is not green.

Works for me without fully constrained sketch. The slider just rule a constraint among other, like drawn manually.

After checking the sketch, you have 1 DOF which is the relative position piston/cylinder. As it should be

Please edit the subject of your first post to fix the typo - aNiMation instead of aMiNation.

More serious project : truck hook lift simulation.

https://duckduckgo.com/?q=hook+lift+sys ... &ia=images

left blue line is a hydraulic cylinder, right blue lines are dump body, center green hook lift system

I loaded file "hook_lift.py" with macro menu.

This simulation helps me get sized all arms, check cylinder stroke and dump body max load angle
