Distances between nodes 3 (and other question)

[scandroglio]

Thx I try to doing a path on XY plot, but when I try to associate the nodes to a new CSYS, that I have previously created, the csys isn't associate.
How can associate it correctly?
How can I change the average on the result visualization?
There is someone can give me a creep power law for Delrin 511P at 80°C or said me where find it?

Regards
