## About this Block

**What it does:** The **Section Body** block sections an Implicit Body with a Plane to create an Implicit Body of the profile.

**Common uses:**

* Calculate Surface Area of a cross-section.
* The Profile can be used as an input in **Extrude Profile**, **Revolve Profile**, **Twisted Sweep Profile**, and **Sweep Profile** blocks.

**Tips:**

* How to calculate the surface area of a cross-section ([https://support.ntopology.com/hc/en-us/articles/360059905913](https://support.ntopology.com/hc/en-us/articles/360059905913))
