First of all, I'm new to Blender (v2.80). Currently working on AI project for which I need to create my data set. I need to render my object from every possible angle. I found a simple solution over here: Script to render one object from different angles

• Create a mesh whose vertices are the desired viewpoint positions, around your body scan. (It's the sphere, in the illustration, named 'Viewpoints')
• Create one camera, and assign it a 'Track To' constraint ('To': -Z, 'Up': Y) with the body scan as target

I was trying to achieve that effect, to make that sphere mesh. I just don't know how to make the sphere empty. It looks like this (my object and camera are inside of the sphere):

I'm sorry for making new post about it, I would prefer to comment that post that I'm referring to, but I don't have enough reputation for commenting posts.
