forge 中如何手动选择楼层

Question

forge 中利用LevelsExtension如何手动选择楼层

Answer 1

选择单个楼层时使用selectFloor 参数1：楼层数组的index，参数2：是否需要平滑过渡的动画

viewer.getExtension("Autodesk.AEC.LevelsExtension").floorSelector.selectFloor(0,true)

想要同时选择多个楼层

var floorExtension = viewer.getExtension("Autodesk.AEC.LevelsExtension");
var floors = floorExtension.floorSelector._floors;
floorExtension.floorSelector._applyFloorSection(floors[0].zMin,floors[1].zMax)

此方法无动画效果，若需要动画则需要自己编写函数，函数可参照_moveToFloor函数改写floorExtension.floorSelector._moveToFloor(floorIndex)
