["Ahmidou Lyazidi" <ahmidou.xsi(at)gmail.com>]

Hi there i just found (a non exposed??) splineDynamics opertor in the SDK, is it what it seems to be, a little bit like the spring operator?
 If yes, i can someone point me to the inputs arguments i tryed this:
//
var oObj = selection.item(0);
applyop ("splineDynamicsOp",oObj);
//
with one ore more splines selected but i had this error:

//ERROR : 2078-EDIT-GetConnectionSet - Object(s) missing. Cannot complete operation. - [line 205 in C:\Softimage\XSI_5.11\Application\DSScripts\operators.vbs]
ApplyOp("splineDynamicsOp", "crvlist", siUnspecified, siPersistentOperation, null, null);


thanks in advance!
