Bundled with Windows 10 and available to download on the Windows Store for Windows 8, 3D Builder lets you construct 3D models and print them to 3D printers. However, you can also export your models to other programs, including to 3D Rad!
3. In the Save window, choose the ‘OBJ File (*.obj)’ file format.
This is the model format that fragMOTION can read. When you click ‘Save’ the first time, you’ll get another one appear straight afterwards. Just click ‘Save’ again without changing anything since this is the .OBJ data file that gets saved.
4. Close 3D Builder and open fragMOTION. Click on File > Import…
5. Find and open your model. If it isn’t too complicated for fragMOTION, it should open it and you will be able to see it in the viewfinder.
But there’s only one problem – the model has gotten rotated to the right! Let’s fix that.
6. Click Transform>Transform Options to bring up the following window:
The first thing you’ll want to do is rotate the model by -90 degrees on the X plane. Click ‘Apply’ to rotate the model up-right. Once that’s done, you can center it to the origin by unchecking the ‘Rotate’ checkbox and checking the ‘Position’ one, then clicking ‘Apply’ without changing anything.
This window can also scale models up and down if needed, since they can appear to be a little large in 3D Rad.
7. Export the model to a DirectX file by clicking File>Export.
8. Using either RadImp, RadImp .NET or 3D Rad’s own ‘custom object’ function, import the model into 3D Rad as either a rigidbody or skinmesh.
9. If all is well with the import, your model should appear in 3D Rad in exactly the same way as it did in the 3D Builder.
NOTE: Because of the way 3D Builder works, it seems that both shadows and dynamic rigidbodies have a higher chance of working properly. In all the models I’ve tried, 3D Rad worked reasonable well with them.
