Make solid visible / Solid not showing in Watch3D

[Howie]

Hi, I am unionizing two solids together using Solid.ByUnion and want to see the result using Watch3D. But as the picture shows I could not see anything in the Watch3D window although the union operation was successful. Does anyone know how to make the solid visible? Thanks!

Dynamo file:
union solid.dyn (15.0 KB)
Revit model:

model.rvt

Hi @_Vijay , thanks for your reply. I followed exactly your codes but it is strange it did not show in the background preview. Are there some settings to set up to see the background preview?
