Yes, of course. And, with the free version of EZNEC, one must be careful
not to exceed the max segments allowed.


I've started reading the manual, I suspect there's little danger of that.
At least with EZNEC+ 4 onwards, not sure about standard version. I suspect
like curves built in segments in Sketchup, or the straight bars in the chains
of the Clifton Suspension Bridge, the amount of fine tuning you'll get in
using more than about 24 segments for a catenary might be an exercise in
diminishing returns, and that even just 3 to 5 might be adequate, if the
deviation from straight is small.
