• Click on "Edit" which is located at the upper left corner of the website.

• Fill the necessary details in the fields section and also under tags section like elevation, levels etc.
• Under all relation click on "new relation" and then select "Multipolygon"
• Under tag section select Building as Yes.

• Now you have member section in your features list of Multipolygon.
• Under member section click on Building
• Now your Building features list will prompt.
• Under All relations > Multipolygon, type Outer.

• Now you have to outline the Hollow section with "Line".
• After outlining select it as Line.
• After selecting it as line new features list window will prompt.

• Under All relation section, click "+" and then select Multipolygon, type role as inner.

• Save it .
• After around 10 mins you will see your hollow building as 3D on osmbuildings website
