We need to draw the balcony arc referring to the floor pen.
We use the same procedure to draw the other balcony.
Once the balcony surface is completed, we pull this two surface 20 centimeters,
we'll find the line between the floor and the balconies.
We have to erase these lines to make the floor and
the balconies join together and share the same surface.
Because we draw the walls and
columns later, we first have to move the floor plan up for
20 centimeters to make it easier for us to keep drawing the walls and columns.
At the moment, we right click the floor plan and select unlock.
Then we select Move tool and click the floor plan.
Press the up arrow key on our keyboards
to make sure the floor plan will along the Blue Axis.
Then we input 20cm in the measurement box to lift the floor plan
to the same height as the slab's top surface height.
So our visibility for the floor plan won't be effective.
Then the floor plan will be above the slab.
Now we're going to add some details, according to the floor plan,
the entrance to the first floor has two steps there.
The first step is only ten centimeter high.
And the floor is 20cm thick.
