view area AR project

hi, i’m working on an ar project for android (i started from the template already present on unreal engine 5). consists of an app that superimposes the 3d model of a large structure that will be built in the future on the square of my city, being a very large 3d model i wanted to insert a view area around the camera to limit the view of the model to a radius of 5 meters from the camera but i don’t understand how to set it up
