Displace Copied LineSOP by Force
If we want to copied LineSOP to be affected by forces we can use the output of the CopySOP as the Spring Source of the SpringSOP. We then use a SphereSOP in combination with MetaballSOP and ForceSOP to create a force-source. In the ForceSOP we have to define what kind of force it should be.
If we want that some points are fixed we create a group with the GroupSOP to define which the fixed points gonna be. We then reference in the SpringSOP in the Nodes tab set Fixed Points Group the previously created group.
