Have created my model. It is a very small component. I intend to 3D print it. When trying to trim or combine solids it says nothing in my model is a solid. How do I make my model a solid?
If you group the geometry it has the potential to be a solid, assuming it is one continuous watertight skin.
If you upload your model here we can show you where you have gone wrong.
Tried another suggestion and I could not make it work. This is what I am trying to make into a solid so I can try 3D printing.
