fillet curves
if selected more than 1 fails - i've read fillet script, it fails from start
earlier I was trying to fillet curves after array - now i know why it fails, for solids it might skip(process time), but for curve I think will be welcome
====
About max distance - wanna start with curves, later will see where it will come,
Before that let's say they are 2 types of fillets - one only with corners, others curves with curvature (curves.js)
*for corners - task one can be done
found article on wikipedia, math around

*for curvature
haven't found any curvature scripts related (forum)
don't now yet about math - but there should be one !!!!
