Great way to view models. Only complaint is with gyro/walk through movement - quite terrible actually. Tracking very quickly becomes out of sync between movement and model.

You can only use this with a really high chief architect software cost (that they changed recently) to high for a user now only for a corporation now they will lose a lot of smaller customers

received 3d file from my architect, was able to see our design in 3d and be able to identify changes that need to be made. i only used it to view, not create/modify
