How to set the value for Capped Isosurface ?

Jean

Hello,

I would like to create a function for capped isosurface.

For displaying this, I use this command :
ExtAPI.Graphics.ViewOptions.ResultPreference.GeometryView = MechanicalEnums.Graphics.GeometryView.CappedIsosurface

But, I don't find the command for :

• selecting the option (Iso, bottom, top)
• defining the value
  

Someone has an idea ?

Regards,
Jean
