Beziers are super and very easy to use to make cables.
1 Add a bezier CURVE shape it to the path you want the cable to follow. You may need to subdivide it for more control points and you may need to click ‘3d’ to allow the control points to be non-planar.
2 When the curve nicely follows the path you want, add a bezier CIRCLE and size it to the diameter of the cable. Change the name of this circle in the ‘ob’ field. I usually use a name like ‘cable_1_rad’ for cable 1 radius. Then select the curve that is the path for cable 1, and in the ‘BevOb’ field in the ‘Curve and Surface’ panel enter the name you gave the circle and BOOM- you now have a cable.
You may have kinks in it depending on the configuration of your control points. 3d control points have 4 dimensions- x,y,z, and tilt which is like rotation. If you have a kink, you can try fixing it with tilt by selecting a control point closest to the kink and typing ‘t’. You can now alter the tilt of the point which you can see by the hash lines along the curve changing as if the curve were being twisted. Tilt alone cannot always fix a kink. You may have to fiddle with control points and their handles to get it right.
This is a cool ship- very greebly. Good luck with your cables.
