# Advanced Viewer Markup Tools & Annotation Options

## **✍️ Advanced Viewer Markup Tools & Annotation Options**  
 

The **Advanced File Viewer** in Ontraccr offers a powerful set of **markup tools** that go far beyond basic annotations. You can highlight, underline, draw, insert text, and style every element to match your review needs — ideal for construction drawings, estimates, and other complex files.

## **🛠 Available Markup Tools**

All tools are accessible from **Annotate Mode** in the Advanced Viewer.

### **✏️ Freehand Draw**

-   Sketch directly on the page (like a pencil)
-   Great for arrows, shapes, or notes

### **🎨 Freehand Highlight**

-   Acts like a paintbrush highlighter
-   Smart detection straightens your lines automatically

### **🖍 Highlight**

Click-and-drag to highlight printed text

Add links to highlight areas if needed

Example: Highlight “Model 12B” and link to the spec sheet

### **📐 Rectangle**

-   Draw customizable boxes over content
-   Choose:
    -   Border type (solid, dashed)
    -   Border color and thickness
    -   Fill color and opacity

### **🔤 Free Text**

-   Add standalone text anywhere on the file
-   Customize:
    -   Font type and size
    -   Bold, italic, underline, strikethrough
    -   Alignment (left, center, right, justified)
    -   Positioning (top, middle, bottom)
    -   Font color and scaling

## **🔠 Text-Based Tools**

These tools help call out or modify existing text in the document:

-   **Underline** – straight underline under selected text
-   **Squiggly Underline** – softer, wavy emphasis
-   **Strikethrough** – cross out specific words
-   **Insert Text** – place new text where none existed

💡 Clicking underlined or highlighted text also gives you styling and comment options.

## **🧽 Editing & Control Tools**

-   **Undo / Redo** – step forward or backward through your edits
-   **Eraser** – remove freehand or shape-based annotations

📌 Save your markup when finished — this creates a new version of the document without losing the original.
