Hi miquik, there is an evaluator available to scripts, see the "scripting" section here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=8814.1

Or also you can use the factory for the "ArrayCurve" command to generate points at equal distances along a curve, see the ReconstructCurve command for an example:
http://kyticka.webzdarma.cz/3d/moi/#ReconstructCurve

There will likely be SVG support coming for MoI v5.

Thanks Michael,
I would like to implement SVG export anyway now. I almost done, just one thing is missing: can I obtain viewport width/height? I need to create the projection matrix but these properties seem hidden.

Thanks

There are .pixelWidth and .pixelHeight properties on a viewport object, so something like:
var width = moi.ui.mainWindow.viewpanel.getViewport('3D').pixelWidth;
