Automated Draw Line with Thickness

Hi guys!

I'm trying to draw an automated line with thickness, but i can´t get a good result.

What i want is:

1. A counter that draws a line in the Y axis.

2. During this automatization 3 contros to control the X and the Z axis and the thickness of the line. 

The purpose of this exercise is to be able to paint a line with some sensors.

Please i need some help with this, i can´t continue till i solve this problem... :(
