Redid the creation of the object.

When creating an object with a mouse movement, the size of the object changes. Previously, this was decided by deleting the old object and creating at the same point a new one with a new size.
Now the geometry of this object is changing.

TA_Enteties.js

this.updateObject = function( parameterName, parameterValue, entity ) {

			let geom = entity.geometry;
	
					let params = {};
					Object.assign( params, geom.parameters );
					params[ parameterName ] = parameterValue;
	
					let newGeom = this.createGeometry ( entity.geometry.type, params );
	
					entity.geometry.dispose();
					entity.geometry = newGeom;

		}

switch (mode.entity) {
	case 'BoxBufferGeometry':

		if (this.currentEntity !== null ) {

			GLOBALSCOPE.updateObject( 'width', width, this.currentEntity);
			GLOBALSCOPE.updateObject( 'height', width, this.currentEntity);
			GLOBALSCOPE.updateObject( 'depth', width, this.currentEntity);

		}
		else{

			this.currentEntity = GLOBALSCOPE.createBox(x, y, z, width, width, width, 'material');
			this.currentEntity.name = "CUBE";

			scene.add(this.currentEntity);

		}

break;

case 'SphereBufferGeometry':

		if (this.currentEntity !== null ) {

			GLOBALSCOPE.updateObject( 'radius', width, this.currentEntity);

		}
		else{

			this.currentEntity = GLOBALSCOPE.createSphere(x, y, z, width, 12);

			this.currentEntity.name = "SPHERE";

			scene.add(this.currentEntity);

		}

break;
default:
break;

Added icons to buttons. I think to leave only icons or all the same with inscriptions. The images of the icons themselves should be redone, of course.

TA_UI.js

addElement( container, elementName, text, imgLink, func ) {

	let dom = document.createElement( elementName );
	container.appendChild( dom );
	let img = document.createElement( 'img' );
	img.src = ( imgLink );

	dom.innerHTML = text;
	dom.appendChild( img );
		
	if (typeof( func ) === 'function') {
	dom.addEventListener( 'click', func, false );
	}

	return dom;
}

TertuisAxis.js

	let buttonCube = taUI.addElement(
		addToSceneContainer,
		'button',
		'',
		"./ico/cubeico.PNG",
		function () {
		taScene.mode.action = 'creationEntity';
		taScene.mode.entity = 'BoxBufferGeometry';
		}

	);
