# Projects & Models
Manage your 3D projects and model files in Vrex
Vrex organizes your work into projects. Each project contains models, sessions, issues, and team members.

## Project Structure

```
Workspace
└── Project
    ├── Models (IFC, Revit, etc.)
    ├── Sessions (past and scheduled)
    ├── Issues (tracked problems)
    └── Team (access permissions)
```

## Creating a Project

1. From the Vrex lobby, click **New Project**
2. Enter project details:
   - **Name:** Project identifier
   - **Description:** Brief summary
   - **Thumbnail:** Optional preview image
3. Click **Create**

You're automatically the project owner with full permissions.

## Uploading Models

### Supported Formats

| Format | Extension | Notes |
|--------|-----------|-------|
| IFC | `.ifc` | Industry standard, recommended |
| Revit | `.rvt` | Converted server-side |
| Navisworks | `.nwd`, `.nwc` | Federated models supported |
| glTF | `.gltf`, `.glb` | Web/interchange format |

### Upload Process

1. Open your project
2. Click **Upload Model**

Large models are optimized during upload for VR performance. This may take several minutes for complex files.

### Model Versions

When you upload a new version of a model:
- The old version is archived (not deleted)
