# Create a Node Model in Blue Locate

Once features have been labeled, a node model A specific spatial arrangement of a set of features (Blue Locate and Blue Read tools only.) During a post-processing step, the Blue Locate and Blue Read tools can fit all of the features detected in an image to the models defined for the tool. The overall pose and identity of the model is then returned. can be generated.

1. Select the labeled features that will compose the nodes of the model. To create a node model of multiple features, hold down the Shift key while selecting the labeled features, or hold down the Shift key and drag your mouse over the desired features.

2. After selecting the labeled features, right-click on the View and from the menu, click on Create Model and select Create Node Model.

3. This will automatically use the selected features and area as the nodes for the model, based on the input image, and open the Model Editor dialog.

4. With the node model created, you can now label the rest of the images/views based on the node model.

5. The node model will be based on the last labeled feature A feature is a visually distinguishable area in an image. Features typically represent something of interest for the application (a defect, an object, a particular component of an object). when you generated the node model. Place this label on the feature, and the tool will automatically generate the node model.

6. The other nodes will indicate that they are potential parts of the node model. Select each feature to label each instance of the node.

7. Label the rest of the images/views based on the previous two steps.

8. Press the Process icon of the tool to apply the model to all of the images.
