Floor plan section cut.
A floor plan is the most fundamental architectural diagram a view from above showing the arrangement of spaces in building in the same way as a map but showing the arrangement at a particular level of a building technically it is a horizontal section cut through a building conventionally at four feet one metre and twenty centimetres above floor level showing walls windows.
If part of a floor is cut through the floor should appear to be solid instead of showing any lines from the top of the walls on the floor below.
If you have not setup any views before choosing this option the dialog box will be empty.
The plan is typically cut at a height of about 4 feet but the architect drawing the plan may cut it at a different height.
Therefor you see in the cut anything that the plane passes through.
The direction of the plane through which the section is cut is often represented on plan drawings and elevations by a line of long and short dashes called a section plane.
It displays a list of section views and floor plan views.
The reason for doing it this way instead of using sketchup s built in section cut tool is that this way eliminates the empty spaces where a mass has been cut revealing the geometry below.
