Curve length as a parameter

[5quid]

I use a little scop to expose the curveinfo to a custom param. probably not the best way but for simple stuff it does the trick.

// JS_CurveInfoNodePlugin
function XSILoadPlugin( in_reg )
{
in_reg.Author = "Jon Swindells";
in_reg.Name = "JS_CurveInfoNodePlugin";
in_reg.Email = "squid@3d-palace.com";
in_reg.URL = "";
in_reg.Major = 1;
in_reg.Minor = 0;

in_reg.RegisterOperator("JS_CurveInfoNode");
in_reg.RegisterCommand("ApplyJS_CurveInfoNode","ApplyJS_CurveInfoNode");
//RegistrationInsertionPoint - do not remove this line

return true;
}

function XSIUnloadPlugin( in_reg )
{
var strPluginName;
strPluginName = in_reg.Name;
Application.LogMessage(strPluginName + " has been unloaded.",siVerbose);
return true;
}

function ApplyJS_CurveInfoNode_Init( in_ctxt )
{
var oCmd;
oCmd = in_ctxt.Source;
oCmd.Description = "Create an instance of JS_CurveInfoNode operator";
oCmd.SetFlag(siNoLogging,false);

var oArgs;
oArgs = oCmd.Arguments;
oArgs.AddWithHandler("Arg0","Collection");
return true;
}

function ApplyJS_CurveInfoNode_Execute(oArgs )
{
var rtnColl = new ActiveXObject("XSI.Collection") ;
for(var i = 0; i < oArgs.count; i++)
{
curr = oArgs(i);
if("crvlist" == curr.Type)
{
//cpset
var cpset = curr.AddCustomProperty("CurveLengthInfo" , false) ;
var param = cpset.AddParameter3( "Crv0Length", siDouble, 0, 0, 1000, true, false )

var newOp = XSIFactory.CreateObject("JS_CurveInfoNode");
newOp.AddOutputPort(param);
newOp.AddInputPort(curr + ".crvlist");
newOp.Connect();
rtnColl.Add(newOp);
}
}
return rtnColl;
}

function JS_CurveInfoNode_Define( in_ctxt )
{
var oCustomOperator;
oCustomOperator = in_ctxt.Source;
oCustomOperator.AlwaysEvaluate = true;
oCustomOperator.Debug = 0;
return true;
}

function JS_CurveInfoNode_Update( in_ctxt )
{
var crvList = in_ctxt.GetInputValue(0);
crvLen = crvList.Geometry.Curves(0).Length;
outPort = in_ctxt.OutputPort;
outPort.Value = crvLen;
return true;
}

save the code as a .js file and plop it in your $workgroup\Application\Plugins. refresh the plugin manager then run the command ApplyJS_CurveInfoNode(); with some curve(s) selected.

ignore the "JS_CurveInfoNode" field, the crv0Length parameter is where you hook into.
