# Create Smooth Angled Lines

## When to Turn Your Model Into a Rig

You can build a simple entity in the modeler, but the design uses diagonal lines you may want to create a rig in the Animator instead to:

* Optimize performance during play
* Improve the appearance by removing distracting jagged edges
* Create a tighter collision boundary for parts of your design so players can approach

In the example below, the jagged purple model has 240 faces and a collision boundary of 40x40x1, while the smooth green model that is linked to a rotated node in the Animator only has 6 nodes and a collision boundary of 50x1x1.

## Related Techniques

The same approach is used to create circular shapes, but it is best used with smaller assets or decorative assets to avoid creating unusual collision boundaries when players approach it in game:

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sandbox.game/en/creator/voxedit/creative-guides/art-techniques/3d-design/create-smooth-angled-lines.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
