Re: Sketch Feature to create linkage mechanism simulator

this code is the one responsible for changing the value of the selected constraint, in this case, my angular constraint is number 9, but you must always subtract 1. I honestly don't know why. The OCC geometry kernel indexes arrays [1..n] rather than the usual C++/Python convention of [0..n-1]. The ...

Re: Sketch Feature to create linkage mechanism simulator

I made a video regarding making a simple four-bar linkage and sliding linkage.

https://www.youtube.com/watch?v=8llFZxxloXg

there is no python scripting in the video , since the animation script doesn't seem to work in the version of freeCAD I'm using.

Re: Sketch Feature to create linkage mechanism simulator

Hello, I'm new to FreeCad and the forum. Could you walk me through step by step on the procedure. I've tried what you did but it did not work for me. I'm hoping to simulate a Five Bar Mechanism one day similar to Dexter Robot. Thank You Sai This 2D technique is only limited to studying kinematics o...

For some users who are not familiar with choosing which files to install
This one worked for me.

Re: Other open freecad files are blocking my macro and drawing workspace

Hi @NewbieSimulator. This is a known issue on macOS and it was resolved only recently. FreeCAD 0.17 development release is needed to be build against Qt 5 for the issue to be resolved. Luckily such builds for macOS are available here: https://github.com/FreeCAD/FreeCAD/releases Well that escalated ...

Sketch Feature to create linkage mechanism simulator

The sketch feature can be used to create linkage kinematics simulation using constraints such as lock, coincide, length, angle, etc... And using the python script you can make an animation out of it. It's good enough that you can make an animated jansen mechanism using it. I'm new at python scriptin...
