Re: Scripting : Little object question.

Hi Guillaume,

You're actually dealing with XSI shortcuts...
The subdiv parameters actually belong to this object:
oPanel.ActivePrimitive.ConstructionHistory.Find("geom")
But XSI kindly provides you with a shortcut. Unfortunately they are
not always reliable...
So if you use that it will always work:

var oGeomOp = oPanel.ActivePrimitive.ConstructionHistory.Find("geom");
oGeomOp.Parameters("subdivu").Value = 2;
oGeomOp.Parameters("subdivv").Value = 2;

Cheers,

Aloys
