[SOLVED] Movement restriction at some points of an object

[SergioPM23]

Hello everyone!
I would like to prevent the movement of some points of an object along the X and Z axes, but allow the movement of those points in the Y axis. Therefore, I want those points to move linearly along the Y axis. I wonder if there is any constraint or any other instruction that could allow me to do this.
I would appreciate any help. Thanks in advance.
Sergio

Hi Sergio,
I think PartialFixedConstraint is what you are looking for.

There is an example at https://github.com/sofa-framework/sofa/blob/master/examples/Components/constraint/PartialFixedConstraint.scn

<PartialFixedConstraint name="partialFixedConstraint" indices="3 39 64" fixedDirections="0 1 1" />

Cheers,
Paul
