# Modifying Existing Constraints

In this page, we'll be going over how to modify existing constraints.

Let's say you've constrained this 2x to the 5x, but now you want to mount the 2x on a spacer. We could constrain a spacer to the 5x, then the 2x to the spacer. That's bad practice, and there's a nicer way of doing it.

## Modifying Insert Constraint

The insert constraint brings two faces together and keeps them concentric. How close the faces are to each other is a parameter within the constraint.

On the left of our screen is our model browser. If we click the `Relationships` folder, we can select the constraint we want to modify. By typing`0.5` here and pressing `Enter` on our keyboards.

If done correctly, the 2x will now be 0.5" away from the 5x.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://wiki.purduesigbots.com/vex-cad/making-a-chassis/inventor-chassis/modifying-existing-constraints.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
