[SOLVED] Avoid changing the trajectory when collision

[Ant0nin]

Hello everyone,

We are trying to model a screwdriver pushing an object. The motion of the screwdriver is imposed thanks to a LinearForceField and we would like to constrain the screwdriver such as it keeps its trajectory (=it moves only along an axis).

However, the screwdriver slippes on the target object and rotates. How could we fix it ?

Thanks for the help,
Regards

Configuration:
Linux Fedora
Sofa 17.12

hey @ant0nin ,

Have you looked at the SlidingConstraint ? There is a scene example in examples/Components/constraint/SlidingConstraint.scn.

Cheers,

Hi @Hugo ,

We looked at the SlidingConstraint by opening the mentioned example. Thank you Hugo! It was perfectly what we looked for. Roughly, here is what we made: First, we added a fixed line in the space. Then we added 2 points we attached to our screwdriver using a RigidMapping. Finally, we added 2 SlidingConstaint between the line and the respective created points. The result is a rail along which our screwdriver can slide.
