I created a model in RHINO and then i used ladybug to calculate radiation on model, when i run ladybug, i would like to see a circular cross section. i dont have a curve, i have a solid model.

You can intersect or extract the naked edge curves from your surface/brep/mesh geometry. There is no explicit solid type in Rhino/Grasshopper (as such). Also have a look here for how to better get support:

Also note that there’s a dedicated forum for Ladybug-specific questions:
