Record the measurements and triangulation of evidence in your notes
and on your evidence sketch. Height measurements are not required on
Cross-projection in sketching is required when evidence items or
locations of interest are on or in the wall surfaces as well as
elsewhere in an enclosed space.
The walls, windows, and doors in a
cross-projection sketch are drawn as though the walls (ceiling and
furniture, if appropriate) had been folded flat on the floor with the
inside (or outside) surface projected up.
Begin making the required measurements of the scene and triangulating
the evidence. Rough sketch of room #6 is attached. (See Figure 2-2.)
Each measurement should be recorded on the notes and plotted on the
9 feet, 4 inches long (inside wall, SW to NW base corners).
9 feet, 6 inches wide (inside wall, NW to NE base corners).
7 feet, 9
2 feet, 8 inches wide (inside of frame, NW to NE base corners).
6 feet, 9 inches high (inside of frame, NW base to NW top corners and
NE base to NE top corners.
Fixing measurement - 8-1/2 inches from the NW base
entrance/exit way frame to the SW base corner of the room.
Door - 2 feet, 7 inches wide by 1-1/2-inch thick by 6 feet, 8 inches
4 feet, 0 inches high (inside of frame, SE base to SE top corners and
SW base to SW top corners).
3 feet, 4 inches wide (inside of frame, SE to SW base corners).
Fixing measurement -"From the SE base corner of the window to a point
on the floor directly below (using a plumb bob) is 2 feet 10
