I'm going to start from the beginning. I'm an intership in a society and we are using UR3 cobot. I'm studying the robot for the moment and I have a problem in executing functions.

How can I use those functions for example ?

To become more familiar with UR robots I recommend you take the UR academy course:
https://www.universal-robots.com/academy/

Then to measure your object, you can indeed use find surface to place the robot at the surface of the object. Then you can record the robot position using the UR function : get_actual_tcp_pose()

Touch the object on each side
Record in variables TCP positions on each side of the object
Calculate the size of the object from the 2 TCP position you previously recorded

I don t know if you are using our gripper but our gripper have a finger position feedback. It is possible to measure object using our gripper.

I just see your additional screenshot. It looks like you want to measure part size with the gripper.

You have first to calibrate the gripper in installation tap.
Then you can get the current gripper open size using the function: rq_current_pos_mm()

how accurate will this be? is it rounded to the nearest mm? I am using the Hand-e

Hand-e have a resolution of 0.2mm.
