1. First we have to change units of our scene to Centimeters. 2. Next we set Grid Spacing. 3. In top view we create the shape of room - using basic Line. 4. Next we have to add Extrude modifier to our new object with Amount = 260 cm. 5. Now, lets convert our object to editable poly. To make this we have to clik right mous button and choose Convert To: Convert To Editable Poly. 6. Now select all polygons and invers them using Flip function. 7. With all polygons selected we have to cut our object - red arrows - using Quick Slice tool. 8. Now choose marked polygon. 9. Use Extrude tool with Extrusion Height set on -25 cm. After extrusion we have to delete this polygon. Thanks to this we made a place for some basic window. 10. In front view, using rectangle 3 times, we have to draw our primitive window. Remember to turn Start New Shape option off - thanks to this our 3 objects will be connected. 11.
