comment Software to measure arc length/perimeter
I haven't tried CloudCompare yet. MeshLab has a measuring tool, but it calculates only euclidean distance (straight), not arc length

Thank you for the detailed response! Maybe I should have provided a bit more of context. Actually the file does not come from CAD models, it's just a mesh. Opening the file is not a problem, and there are other alternatives for the format. Approximating a free-hand curve to a Cartesian equation would be more difficult than calculating manually all the distances, I suppose! Finally, I have no problem for an eventual migration of my answer, but I'm not sure that Super User it's a good fit!

Thank you for your answer anyway! I must admit I am not very familiar with graphic design and its applications...I just didn't find another stack exchange site appropriate for my question!

I've seen in some other answers that 3D question are off topic. I could be interested anyway in some program for arc length measurement on a 2D image (but if you have suggestion for 3D it's better ;) )
