Hi Amarita,
You raise an important point?each surface requires computational effort at each time-step during the simulation to account for the variance in shading and reflection etc. In DesignBuilder you draw the curved surface and can specify the number of segments the surfaces are divided into so that you can hopefully find the right balance between simulation time and accuracy.

Thank you so much everyone for your help.
What I understood from your answers is that even if I manage to draw curved surfaces using interfaces like Design Builder or Sketchup, the surfaces would be broken into flat segments during EnergyPlus calculations. Please rectify if I am wrong.
