Prepare a Try-On Model

Configure each ring before you add Try-On to a website. The configuration controls the ring size, position, and rotation on the tracked finger. It also tells Mini Viewer that Try-On is available for the model.

Watch the Try-On setup video on YouTube.

Before you start

Make sure that the ring model is available in your Drive inside iJewel3D Platform. The model must have a clear inner opening. Auto Fit uses this opening to calculate the initial fit.

Enable Try-On

1. Open the model from your Drive in the iJewel3D editor.
2. Open the Try-On settings.
3. Turn on Enable AR.
4. Select Enter Setup.

Setup mode displays a cylinder inside the ring. The cylinder represents the tracked finger.

Fit the ring to the cylinder

Select Auto Fit first.

Auto Fit finds the inner ring opening and provides an initial position and size. If Auto Fit finds several openings, select it again to inspect the next result.

Use these controls to correct the result:

Control	Use
Model Size	Match the inner ring opening to the cylinder diameter.
Position	Place the center of the ring opening on the cylinder axis.
Rotation	Align the ring band with the cylinder. Point the ring head in the direction of the arrow.
Front, Top, and Side	Inspect the fit from fixed viewpoints.
X 90°, Y 90°, and Z 90°	Correct the model orientation. Use these controls for large corrections.

The cylinder must pass through the center of the ring opening. The band must surround the cylinder evenly. The cylinder must pass through the center of the ring opening. The band must surround the cylinder evenly. The arrow inside the cylinder shows the correct direction for the ring head.

Check the fit from all three viewpoints. Rotate the model until the ring head points in the direction of the arrow.

Preview and save

1. Select Exit Setup.
2. Select Preview in AR.
3. Give the browser camera access.
4. Check the ring size, position, and direction on your hand.
5. Exit the preview.
6. Correct the setup if the fit is wrong.
7. Save the model to your Drive.

The saved model contains the Try-On configuration. You do not need to download or host a separate configuration file. Mini Viewer receives the model and its configuration through loadModelById.

Public file access

The file must be Public in its share settings. loadModelById cannot load a private file from your Drive.

Test the saved model

After you save the model, test its file ID with the Direct Integration example. The Mini Viewer Try-On button appears only when the saved configuration has Try-On enabled. If the old fit appears, save the model again and reload the product page.
