Not sure if this is normal as I haven’t seen it before, appears in sketchup and skechip viewer.
It basically cuts out some of the model no matter where I place the camera or what component or group it is on.
I have a complete model loaded there but yet only see 1/4
That looks like clipping. You can learn about how to avoid clipping on the SketchUp help and/or by searching this forum. If you are using parallel projection that is often a cause due to the way it handles zoom.
