If the 3D modeling has completed and no 3D model is visible in the Globe view, it's usually related to the model being placed under ground.
In this case use the height adjustment in the top right to bring the model above ground. The height adjustment is meters, and the may need everything from just a couple of meters to a few hundred meters.
How much the model needs to be adjusted depends on the input data from the images. The model position is calculated based on the EXIF data from the images, so a bad placement is usually caused by bad GPS data.
