The main chamber plans

The interactive drawing shows the secondary geared master ellipse, the plot of its equator's lower turning point and the vertical projection line that emanates from the equator running through the main chamber's roof cavities as has been explained on the previous pages. You can zoom in to show the upper and lower chambers in more detail.

It is not just the main chamber's roof cavities that contain astronomical data but also the wall joints in the main chamber, and to bring these into the analysis the plan views of the chamber need to be displayed onto the drawing. If you display the plan views of the main chamber they are shown in a manner which has been derived entirely from the details of the stonework and the 3D axis system of the pyramid, and each of the pieces of the plans needs to be explained.

First, there are numerous pieces of 'damage' to the stonework of the main chamber, all of which are part of the original architect's design plans and these can be displayed by adding a explanatory illustration to the interactive drawing by clicking here .The names of the sections of the plans are shown on the drawing, and you can see that in the manner in which they are displayed all of the major 'damaged' sections (marked in red) fall on the right side of the drawing and are therefore in the area of the pyramid that is not covered by the moving vertical projection line.

The organisation of the plan sections has been done according to the following logical rule which defines the axis system of the building :


When the main chamber plans are displayed in this way then

  1. The right side of the moving vertical plot line aligns with the shaft hole on the north wall
  2. The center line of the moving vertical plot aligns with, and defines, the back of the coffin
  3. The left side of the moving vertical plot aligns with the left side of the west wall

which can be seen by clicking here .
