# Place your first objects

Object placement is where most users hit their first wall: things spawn somewhere unexpected, scale to zero and become unselectable, or disappear into a scene with no obvious way to find them. This page covers all three.

![Build mode with the asset library expanded along the bottom, My Assets category active, ready to drag a chair or other prop into the empty scene](/files/fdiS1XZeIJNKlzV87sAW)

## What's getting in the way

Three problems account for most of the early friction: objects appear in unexpected places, aligning them is fiddly, and scaling one to zero makes it unselectable and hard to delete. The steps below cover all three.

## How to do it

{% stepper %}
{% step %}

### Open the asset library

The library isn't open by default. In Build mode, click **Add an Asset** to bring it up along the bottom of the screen; click away into the scene to dismiss it. Categories tab across the top: Characters, Furnishings, Mannequins, My Assets, Objects, Populators, Primitives, Roads, Sets, Vehicles.
{% endstep %}

{% step %}

### Drag the asset into the viewport

Click and drag a thumbnail. The library auto-minimizes the moment you start dragging so you can see the 3D scene. The asset lands at the cursor's projected ground point. Hold `Ctrl` while dragging to snap the asset onto another surface you're hovering over instead of the ground.
{% endstep %}

{% step %}

### Let go, then select the object

Release the asset, then click it in the viewport. The contextual menu opens above it with the swap, color, transform, details, and more-options controls. The default handle is a simplified smart gizmo; for the classic move gizmo with axis arrows, click the transform control in the menu. `Tab` toggles the gizmo type, and `T` switches between World and Local space.
{% endstep %}

{% step %}

### Adjust the position

Drag the gizmo arrows for axis-locked movement, the small squares between arrows for plane movement, the elevation handle for vertical lift. Local space moves the object along its own axes; World space along the scene's. For precise placement, type values into the contextual menu's transform panel directly.
{% endstep %}

{% step %}

### Lock it once it's right

Click the lock icon in the contextual menu's more-options. The object can't be selected from the viewport or the outliner until you unlock. Lock the terrain and any large [populator](/build/populators.md) backbone before you start adding props on top of them; you'll stop dragging the world by accident.
{% endstep %}
{% endstepper %}

## Avoiding the most common mistakes

{% hint style="warning" %}
**Don't scale all three axes to zero.** It makes the object unselectable from the viewport and unreachable from the gizmo. Recover via the [Scene Outliner](/build/scene-outliner.md): find the object by name, right-click, reset transforms.
{% endhint %}

{% hint style="warning" %}
**Don't lose objects off-screen.** Smart snapping plus a fast drag occasionally launches an object outside the viewport. Open the [Scene Outliner](/build/scene-outliner.md), select the row, press `F` to frame.
{% endhint %}

## Swapping models

If the chair you dragged in isn't quite the chair you wanted, click the object and pick the **swap-model** icon – the leftmost icon in the contextual menu. The library reopens in swap mode and only shows alternatives the system recognizes as the same concept (chairs, in this case). One click to swap; the new asset inherits the original's position and rotation.

## Selecting multiple objects

The default click is single-selection. To select a group:

1. Click the **marquee** icon in the toolbar at the bottom of the screen, next to the asset-library icon.
2. Drag a selection box across the viewport.
3. Apply a transform, swap, or [save-as-set](/build/sets.md) to the whole selection.
4. The marquee toggles off after one use; click again to re-engage.

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 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.intangible.ai/overview/get-started/place-your-first-objects.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.
