[Ipe-discuss] Fwd: How to draw a spring?

[Hemza]

Thank you Nathaniel and otfried,  that is very helpful.
I already used svgtoipe to convert some Tikz generated spring to ipe (see
attached files).
It is also very interesting to know that tikz could be used within Ipe,
however my aim to use ipe is to avoid Tikz which save me time and effort.
Tikz is powerful and I already use it for some nice drawing but, compared
to tools like inkscape and ipe, it requires more time to learn. Thus I keep
it for some other types of drawings.

Writing an Ipelet is the best thing to do in my case, unfortunately, one
needs to learn Lua, maybe when I find more time and be more confident with
ipe !!!!
