Hi Anis, for tasks like this you have to undertake some "reverse engineering" type processes as Michael T described above.

Since you don't have the original rail, you need to create a replica of it before you have something that has a measurable length.

Hi again Anis,

The script I spoke of was the total length of the joined center line geometry, not the tube geometry itself. Just wanted to clarify.
