To start 3DPlay and open content, you have the following possibilities:
Use one of the standard methods offered by Windows 10 to start 3DPlay with no file opened. Then, from 3DPlay, in the top bar, click Add to open a file stored on your device.
Note:
You can also search for the last models opened on your device.
Double-click a file to open it in 3DPlay.
Run Cortana, and say "3DPlay, open the last model" to run 3DPlay and open the last file you used.
Start the 3DEXPERIENCE platform, and browse for files in 3DSwym, 3DSpace, or 3DDrive, or run a search. Select the model, and from the Compass, select 3D Modeling
Apps, and then 3DPlay for Windows 10.
