Mahesh:
The video shows how to make an Object (Chair icon on ToolBox) not a Wall (Wall icon in ToolBox), Objects do not host doors and windows, only Walls do. In AC 16 you can create a
Composite Structure to use as a Wall (in the Help files see Configuration > Attributes > Composite Structures > Define a Custom Composite Structure), which will display the various skins in plan and section, but not 3D. AC17 has introduced a new attribute (Building Materials) that will display the wall composition in 2D, Section and 3D.
