Automatic zoom on glb 3D models

I am new to the cesium community, I would like to automatically zoom in on the different 3D glb models loaded as my projects are not zoomed in properly and I would like cesium to allow me to view them through its options.
you can understand my problem through these two screenshots on one of the cesium examples and my project
the yes.glb model is loaded but I can’t see it because it is far away
Thank you,

Hi @Takieddine

The simplest way to zoom into a Model is to use the viewer.zoomTo function, as shown in this Sandcastle.
