In order to create a project in inspectAR using Eagle, you are going to need to upload your board layout file into the tool.
Step 1: Create a Project
Step 2: Find your Eagle Board File
Navigate to your project directory and find your board layout file. You’ll know you have the right one from the icon shown below, as well as the file extension *.brd. To ensure the file is in the correct format - make sure you can open, and re-save the file in the latest version of Eagle.
Step 3: (Optional) Add a BOM
You can also add a CSV bom to your project.
Give your project a name and then you are good to go!
