3D Builder is a free application available for Windows users (version 8.1 or higher) that allows you to create and edit 3D models using a range of simple, yet powerful tools. Unfortunately, 3D Builder is not available for Mac users.
- Open 3D Builder and create a new scene.
- Click on 'Add', select 'Load object' and choose the model that needs repairing.
- Click 'Import model' to start working with your file.
- If your model needs repairing, it will have a red outline and a notification as seen below. Click on the notification to instantly repair your model.
- Once repaired, make sure you click on the 'save' icon at the top right corner of the application. This will overwrite the same file you uploaded instead of creating a new file, so when you go to upload to BuildBee again, choose the same file.
Netfabb is a free online tool that allows you to upload your STL files and re-download a repaired version. We recommend this tool for Mac users as an alternative to 3D Builder.
- Login with your Autodesk account, which will be the same as your TinkerCAD login.
- Click 'Upload 3D model' and choose the STL file that needs repairing.
