## About this Block

**What it does:** The **Boolean Union** block joins a list of Implicit Bodies into a single Implicit Body. A blend is applied at the intersection of each body to control the transition between each volume. The Blend type can be sharp, rounded, continuous, or chamfered.

**Tips:**

* Apply a fillet by using the 'Rounded' Blend Type.
* Apply a chamfer by using the 'Chamfered' Blend Type.
* To retain the shape features, use the 'Sharp' Blend Type.
* To achieve a smoothed appearance between edges, use the 'Continuous' Blend Type.
* Join more than 2 bodies by clicking on the + button in the upper right-hand corner of the Implicit Body List block.
* The angle input on the Chamfered or Rounded blend type can't be changed.
