# Convert and Visualize CBCT in 3D

Stack. Align. Measure.

***\*Available in Trial and Business plans.***

The **Review** feature allows you to visualize, stack, and evaluate CBCT files in 3D.

## Step 1. Upload your CBCT file 

CBCT data may come as:

-   A single file, or
-   Multiple “slices” (anywhere between 1–800 `.dcm` files).

Before uploading to Smilecloud, make sure your file is **unzipped**.

-   Select all `.dcm` files
-   Drag & drop them into **Documentation**

📌 In Documentation, you can only preview CBCT in **2D planes**.

## Step 2. Open in Review

To unlock 3D visualization:

-   Go to **Projects**
-   Select **Review**
-   Choose your CBCT file
-   Set the density and **Add to Scene**

Inside Review, you can:

-   Create cross-sections (double click anywhere)
-   Measure distances directly in 3D
