# Markup & Annotations
Draw, annotate, and document issues in 3D
Vrex provides tools to mark up models during reviews, helping teams identify and document issues in context.

## Drawing Tools

### Access Drawing Mode

**In VR:**
1. Look at your left-hand toolbelt
2. Click the **wrench** icon
3. Select the **paintbrush** icon

**On Desktop:**
1. Click the **Tools** menu
2. Select **Draw**

### Drawing Types

#### Surface Drawing

Drawings that stick to model surfaces.

**Best for:**
- Marking specific locations
- Indicating problem areas
- Annotating floors, walls, equipment

**How to use:**
1. Point at a surface
2. Hold trigger/click and draw
3. Release to finish the stroke

#### Air Drawing

Drawings that float in 3D space.

**Best for:**
- Outlining volumes or zones
- Sketching where no surface exists
- Conceptual overlays

**How to use:**
1. Point in the air (not at a surface)
2. Hold trigger/click and draw
3. Drawing floats where you create it

### Drawing Options

| Option | Effect |
|--------|--------|
| **Color** | Change stroke color |
| **Thickness** | Adjust line width |
| **Erase** | Remove individual strokes |
| **Clear All** | Remove all drawings |

### Tips

- Draw slowly for smoother lines
- Use bright colors against dark surfaces
- Combine surface and air drawing for clarity
- Keep drawings simple and focused

## Screenshots

Capture what you see for documentation.

### Taking Screenshots

**In VR:**
1. Frame your view
2. Click the **camera** icon in your toolbelt
3. Screenshot saves to your account

**On Desktop:**

### Screenshot Location

Screenshots are stored in:

### Best Practices

- Include context (show where the issue is)
- Capture before and after views
- Add markup before screenshotting
- Name files descriptively when exporting

## Issues & Notes

Create trackable issues attached to specific locations.

### Creating an Issue

1. Navigate to the problem location
2. Click **Create Issue** (or press `I`)
3. Fill in details:
   - **Title:** Short description
   - **Description:** Full details
   - **Priority:** Low / Medium / High / Critical
   - **Assignee:** Who should handle it
4. Click **Save**

### Issue Markers

Issues appear as pins in the model:
- 🔴 Critical
- 🟠 High
- 🟡 Medium
- 🟢 Low

Click a pin to view issue details.

### Issue Integration

If your workspace has integrations configured, issues sync to:
- BIMcollab (as BCF topics)
- Procore (as observations)
- Your project management system

## Measurements

Measure distances and dimensions in the model.

### Taking Measurements

1. Select the **Measure** tool
2. Click two points
3. Distance displays between them

### Measurement Types

| Type | Usage |
|------|-------|
| **Point to point** | Direct distance |
| **Horizontal** | Level distance only |
| **Vertical** | Height difference only |

### Accuracy Note

Measurements are as accurate as your model. Verify critical dimensions against source documentation.
