# Merge CAD Bodies

## About this Block

**What it does:** The **Merge CAD Bodies** block merges multiple CAD bodies into a single CAD body.

**Common uses:**

* Merge Shell and Infilled bodies

**Tips:**

* To fix *Merged body creates disjoint solids. This is currently not allowed.*, We currently don’t merge two disjoint parts. The workaround is to export it as individual CAD bodies by using the **Split Mesh** block and then merge in your CAD software.
* To fix *Input bodies are intersecting.*, ensure that the inputs are not intersecting.
* Use the **Refine Mesh** block, if using CAD Body from Quad Mesh to get better results.

***

Combine a solid body with multiple inner voids to create a body with inner shells.
