There are a series of menu options in the **Static Mesh Editor** under the **Collision** menu entry, named *##DOP*, these are the **K-DOP** simple collision generators. **K-DOP** is a type of bounding volume, which stands for *K discrete oriented polytope* (where K is the number of axis aligned planes). Basically it takes K axis-aligned planes and pushes them as close to the mesh as it can. The resulting shape is used as a collision hull. In the **Static Mesh Editor** K can be:

**10**- Box with 4 edges beveled - you can choose X- Y- or Z-aligned edges.**18**- Box with all edges beveled.**26**- Box with all edges and corners beveled.

See below for an example. This tool is quite handy for packages full of pipes, pillars, and railings:
