# Inspect Points and Edges

### Inspect Points <a href="#inspect-points" id="inspect-points"></a>

When using the Moasure device, it's important to understand the three-dimensional coordinate system that helps you measure and map out spaces. This system is based on three axes: X, Y, and Z, along with angle measurements. Each measurement consists of Points and Edges. Points are locations where you've paused, and edges are the lines that connect these points.

### Starting Point

Moasure uses the Cartesian coordinate system to define spatial relationships and measurements. Your starting reference point (the origin) is your initial position where:&#x20;

* #### X = 0
* #### Y = 0
* #### Z = 0

All subsequent measurements will relate to this starting point.

The first two measured points define the X-axis.

### Inspect Points

Tap on a point to inspect/view the coordinates. The coordinates are as follows:

* #### X: Represents one horizontal direction and measures distances and positions from the origin (starting point).
* #### Y: Represents another horizontal direction, perpendicular to the X-axis, and measures distances and positions from the origin.
* #### Z: Represents the vertical direction and measures elevation changes and positions from the origin.
* #### Angle: Displays the angle between edges or surfaces.

### Inspect Edges

Tap on a selected edge to inspect/view the length, rise, and run.

* #### Length: The total distance measured along an edge or line from one point to another.
* #### Rise: The vertical distance between two points, representing the change in elevation (Z-axis) from the starting point to the endpoint.
* #### Run: The horizontal distance between two points, representing the horizontal distance from the start point to the endpoint.

# Agent Instructions: 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:

```
GET https://docs.moasure.com/en/moasure-app/inspect-points-and-edges.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
