Create 3D Digital Designs is an Android application developed by GTSStar .co. It falls under the category of Utilities & Tools and is available for free. This app allows users to edit and view 3D objects, supporting models in STL, OBJ, and 3DS formats. It offers the ability to export designs in STL and OBJ formats for 3D printing or save them as SCENE files for future editing.

The app provides a user-friendly interface where users can add geometric shapes from the right panel to create their own objects. Additionally, they can import existing models in STL, OBJ, and 3DS formats to the platform. The app supports cutting and fusion of objects, offering a versatile editing experience.

To cut objects, users need to add object A and object B to the platform, select object B, choose the "Hollow" material from the right panel, and export the work as an STL or OBJ file. The cutting process may take a few minutes depending on the complexity of the objects.

For object fusion, users follow a similar process of adding object A and object B to the platform. However, instead of selecting the "Hollow" material, they can choose any other material from the right panel. The fused object can then be exported as an STL or OBJ file.

The app also allows users to navigate the platform by using touch gestures. They can rotate the view with one finger, zoom in and out with two fingers, and move the camera with three fingers.

Overall, Create 3D Digital Designs - 3D OBJ Viewer is a versatile application that enables users to create and manipulate 3D objects. With support for multiple file formats and intuitive editing features, it offers a convenient platform for 3D design enthusiasts.
