Maybe you can use "OnBeginSequence" ...but I can't make it works...xsi freeze
each time when I start render because I don't know the correct scripting syntax
.

I'm not a scripting specialist but here is the idea to render some lines at
render time :

///////////////////////////////////////////////////////////////////////////////
/////////////////////////////////////////////////
//<OnBeginSequenceJScript code>
function XSIApplication::OnBeginSequence( CustomData, RenderType, FileName,
Frame, Sequence, RenderField, UnUsed )
{
Application.LogMessage( "*** JScript Event - XSIApplication::OnBeginSequence: *
**");

// -- ---- ---- ---- ---- ---- ---- ---Rendered lines script-- ---- ---- ------
-- ---- ---- ---- ---- ---- ---- -----

//select the rendered lines ( you must add your lines to a group named
"rendered_lines" ).
SelectObj("rendered_lines", null, null);
var oRenderedLines = SelectMembers(null, null, null);

//set the thickness for the lines here.
var oRadius = 0.1

//Create a temporary circle ( deleted with an "OnEndSequence"event ? )
var oCircle = CreatePrim("Circle", "NurbsCurve", null, null);
SetValue(oCircle+".circle.radius", oRadius, null);
RenderLines( oRenderedLines , oCircle )

//At the end the lofted lines are also deleted with an "OnEndSequence"event
Is it possible ?

//The RenderLines function
function RenderLines( limbs , profile )
{
for (var i = 0 ; i < limbs.count ; i++)
{
ApplyGenOp("Extrusion", "NurbsSurface", profile + ";" + limbs(i), 3,
siPersistentOperation, siKeepGenOpInputs, null);
FreezeModeling(null, null, null);
}
}

return 0;
}

//</OnBeginSequenceJScript code>
