Reading Grid Point Stress Data using Tcl

Hello everyone,
I am new to Tcl . I am interested in reading the result file(H3D FILE) i.e read Grid Point Stress Data of particular node ids .
What commands should be using ?Please reply if you have tried this before!!

Thanks Tinh,
I got off to to a start with help of Hyperworks help !!.
I was looking for any particular tutorial where results are extracted from the model .I am stuck with the Hyperview Hierarchy sequence !!

Hello Tinh,
Coming back to forum after couple of months!!
I am facing difficulty using the SetDataType command in the ContourCtrl class of Hyperview
Though I can set the query to Displacement, Grid Point Stresses(Prop 1),etc but I am not able to choose sub options like Mag,X,Y,Z and Von Mises ,Signed VonMises, respectively.How do I do it ?
Your help is very much appreciated !!
Thanks and Regards,
Girish

Yes it works !!
With respect to the Hyperview help on Tcl/TK Classes , the description on SetDataComponent is a bit misleading. It says the options can be either node,line,shell or solid.
Can you elaborate on the following classes(with significance to displaying a contour plot) :
1. SetDataComponent
2.SetShellLayer
3. SetDimensionEnabled
Yes, hw help has some mistake while explaining functions
I do not ever use above functions, I just guess.
so SetDataComponent => will set component of DataType, example: DataType=Displacement, DataComponent=X
it's better for you to try some values, and then look for any affect

Hello tinh,
Greetings !!
I intend to read all the labels of the entity sets available in a HyperView Model file. How should I do it ?
I tried using GetSelectionSetHandle command, but it requires that I get the handle for each set then read the label .
Something similar to GetSelectionSetList will be helpful or any other method ?
