# Angle Field

## About this Block

**What it does:** Creates an angle field from an Implicit Body and a vector input to help you determine if your model needs support structures.

**Common uses:**

* Visualizing overhang angles and determining the need for support structures for additive manufacturing.
* Combine with the **Overhang Constraint** block in topology optimization.

**Tips:**

* Use the Field Viewer (f) and Probe Values to see what the angles are.
