How to create longitudinal profile

I want to create a longitudinal profile for a cylinder.. Can someone give suggestions, how to implement it by step by step. As i don't have any idea of implementation..

Can you elaborate on what you mean by longitudinal profile? Do you mean like a cross-section?

We have clipping planes that are able to create cross-sections, but they are applied to models and 3D tilesets, not basic geometries.
