# Primitives

In Edit mode, basic geometric primitives can be generated directly within an existing object. This allows for seamless integration of new geometry into the current mesh structure without creating separate objects. \
Primitives provide a foundation for modeling, allowing for further modifications using edit mode tools.

Primitives are created in a multi-step process:

1. First, the shape of the primitive is defined using the cursor.
2. After placement, a context menu appears, allowing adjustments to its form, dimensions, and segment count.

* **Box** – Creates a six-sided cube that can be modified by adjusting its dimensions.
* **Sphere** – Generates a smooth, rounded shape with adjustable segment density.
* **Cone** – Creates a tapered shape with a circular base, customizable in height and segments.
* **Cylinder** – Produces a uniform cylindrical form with a defined number of sides.
* **Tube** – Generates a hollow cylinder with inner and outer radius controls.
* **Torus** – Creates a ring-shaped object with adjustable inner and outer radius, as well as segment density.
* **Polyhedron** – Generates a multi-faced geometric shape with customizable parameters for different polyhedral structures.

## 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://help.vectary.com/documentation/design-process/edit-mode/primitives.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.
