Hello discourse.threejs.org Friends,
It may be interest to have a particular GridHelper.

Thanks for the great Three.js Team!

PS: Basically this part is the rect. grid code…
var plane=[];
var qty=6;
var hz_qty=20;
var vt_qty=10;
var half_hz=(qty*hz_qty)/2;
for(let p=1;p<=qty;p++){
plane[p]=new THREE.GridHelper(hz_qty,vt_qty,'#666','#666');
plane[p].position.set(-half_hz+(hz_qty*p)-hz_qty/2,0,0);
scene.add(plane[p]);
}
