Hi!
Well SVG import is not really ready in IanniX because it’s pretty time-consuming to develop it (the framework — Qt — that we use doesn’t include a SVG parser).
To start with SVG, you can try polylines or pathes. Take a look at “Script sample – Xenakis Metastaseis.nxscript” to have an example.
But don’t worry, we are working on a real SVG import, it’s in our project roadmap.
Good luck!
