As you'll have spotted, Microsoft's gone a little 3D crazy in recent versions of Windows 10 on the 'Desktop', and 'Mobile' has been something of a poor relation. But did you know that the core 3D Builder UWP application also works on Windows 10 Mobile, letting you join in the 3D object building fun? Potentially, you could create something for the Microsoft 3D library that ends up being used by others in their own creations. The catch? The UI is cramped under Windows 10 Mobile. I guess fiddling with your display settings might help, but only if you have good eyesight!!

From the Store description:

View, capture, personalise and print 3D models using 3D Builder.

Download many kinds of 3D files and edit them using the 3D modelling space. Take a picture with your webcam and make it 3D. Personalise 3D files by embossing your name, or combine models and pieces to make something new. Build from scratch using simple shapes.

Don’t have a 3D printer? That’s not a problem – you can order a professional-quality print of your model from inside the app and it’ll be sent to you by i.materialise.com, our preferred online printing service.

I attempted to use 3D Builder and to create something, but it's all too much for my eyes and my brain! Sorry....

The 3D world can be spun around with your fingers, then use the pop-up menus and panes to insert objects and manipulate them to your heart's content.

Browsing through the starter library of basic objects...

Steam train chosen. Maybe it's a learning exercise for the user, to get the wheels rotated and in place?(!)

I'm sure you'll have more luck than I did, perhaps armed with more aptitude and more patience!

You can grab this in the Store here. Comments welcome if you master the interface under Windows 10 Mobile - I tried and failed! Have you managed to build anything worthwhile?
