im using bezier curve and bezier circle to make tubing. im using the tubing to make a body that looks like it was made of cables. can you rig the tubing to make it move like a normal model thats being animated like an arm being moved
Enter in the edit mode of the curve, select a control point, use Ctrl + H as shortcut select Hook to New Object.
Blender will generate an empty as a helper get out from edit mode and select the empty and after that select the rigg enter in Pose Mode, select the bone that you want to relate the control point of the curve (or the emty object) and use Ctrl + P , from the menu select Bone. Repeat this for every control point of your character.
It`s hard if you have a lot of curves, try to trick it with other techniques.
Model the character in mesh, use Multiresolution and sculpt the tubes after you increase the multiresolution to 4 or 5. After you finish the sculpt reduce the Multiresolution to 0 for prewiev and 4 or 5 for render. Rigg the character.
Add 2 or 3 tubes with the bezier curve technique just for effect.
Option 1 - Adding a Shrinkwrap modifier to the bezier curves.
Option 2 - If you need more precise control of the points on the curve, you can try the Hook modifier.
Option3 - Just convert your bezier tubes to mesh using Object>Convert to>Mesh from Curve/Meta/Surf/Text Then weight it to your armature like any other mesh.
