The Entity Tool in Ango Hub

How to add an Entity tool to your project

From the project’s Settings tab, enter the Label Set section.

Click on Add Category. From the list that appears, click on Entity.

A new row will appear named Entity. Click on it to expand it.

Give your entity tool a title.

Enable the Required toggle if you want to force labelers to place one. When the toggle is disabled, labelers will be able to save and move to the next asset without creating an entity.

If you would like to ask labelers further questions, for example, if you want to show a further radio after placing the entity, click on Add Classification and add a further question. More on nested questions here.
