The AutoCAD model, oproprxiv.dwg (file format for Release called AutoCAD 2000 and a second copy in R14 format written by AutoCAD 2000) began in a very early form of AutoCAD, probably version 10, but I no longer remember. Much of the model had been created previously in another CAD program (ARRIS) and portions in still other early CAD programs on Macintosh and PC machines, but the AutoCAD model was constructed entirely from the data; no transfer of information from the prior program was accepted.
The file has been migrated automatically from version to version of Autodesk's DWG file format via transparent AutoCAD processes. AutoCAD 2000 is not the most current version of the program, but it is the most current version in use at CSA. (CSA, the Center for the Study of Architecture, has been the organization directed by Eiteljorg since its founding in 1985; see http://csanet.org.)
Database linkage has been tried, and various rendering possibilities have been tried. There may be artifacts of those two processes in the CAD file, but there are no database links currently maintained in the AutoCAD file except as noted below (no implicit links at all), and there are no intentional data items for rendering.
Line colors and types have no meaning by intent. Only layer names have been used to convey information about the blocks that have been put into the CAD model.
The 0,0,0 location is roughly at the juncture between the south wall of the upper courtyard of the older propylon and the parastas wall that rests on the steps leading from lower to upper courtyard. "Drawing north" is aligned to the parastas wall. There is a second coordinate system (in AutoCAD parlance, a user coordinate system) called north that aligns the y-axis of the model with the north arrow (with the same 0,0,0 point as the base coordinate system), making the model align itself properly with the compass points. (It should be noted, however, that the north arrow has not been carefully aligned via computations and may be off by a few degrees.) There are no other user coordinate systems saved with the model.

There are scripts for use with the AutoCAD model; they are supplied in the same directory as the model itself. Running the scripts will result in the display of certain portions of the model (layers) while others are suppressed to provide specific illustrative needs. Their names are meant to be helpful. Those beginning AR refer to one of the archaic periods; those beginning CL refer to one of the classical periods of the entrance. Following either AR or CL are Roman numerals to indicate the phase within the archaic or classical periods; the M or P following indicates whether the selected material is for a plan view only or a fully modeled view. There follows an I, 1, or 2. I indicating only the in situ material will be included; 1 indicates the Eiteljorg reconstructions will be included; 2 indicates the Dinsmoor reconstruction will be included.
Examples: ARIP1 will display the first archaic period -- the period following 560 B.C.E. -- as a plan only and will include Eiteljorg's reconstructions; ARIIM2 will display the second archaic period -- 490-480 B.C.E.-- as a 3D model with the Dinsmoor reconstructions. Unfortunately, Windows may misidentify script files as screensaver files; they are simple text files that can be read by AutoCAD, and the misidentification should have no impact on their utility.
There are also prepared views. Some are named with letters of the alphabet to indicate the vantage point (see below); all use the 0,0,0 point of the model as the aim point of the view. Others cannot be easily defined; they are not important enough either to remove from the model or to define fully here.

Link to Data Tables Linked To CAD Model
There are two external data tables, one with data items that apply to individual blocks in the model and one with comments about the model more generally. The data items about blocks are in a data table called OPattDATA.FP5 (a FileMaker file -- also available as a tab-delimited ASCII file called OPattDATA.txt). The structure of the table is discussed below. Model layers named with a D in the first position contain icons that indicate the blocks for which data items have been supplied and the number of the individual data item.
Notes of a more general nature are contained in another table (OPcomments.FP5 or OPcomments.txt). Layers named N plus a numeral (e.g., N1, N2, etc.) have icons and numbers to indicate the portions of the model discussed and the comment number of the database entry.
Any user may refer to the appropriate CAD layer(s) to find the references to external data table entries. Similarly, a user of the data tables will find there the names of the layers needed to see which items are referenced. This system --icons in the CAD file with explicit links to data tables --is intended to make it possible for the files to be migrated in the future to new formats without fear of losing information.
Crucial to the use of the CAD model is an understanding of the layer-naming system used. Each layer is named with a string of characters --18 in all --and each character or group of characters indicates an attribute of the material on the layer. (This system both informs and is governed by the CSA Layer Naming Convention which may be found on the CSA Web site, http://csanet.org/inftech/csalnc.html. The CSA Layer Naming Convention is also included here as a document in the archived materials, though the version at the Web address may be more recent.)
The names may be parsed with this list of characters and attribute meanings.
Character One: type of layer
C - Cracks or other damage to a 3D block or surface (may be used with plan layers if the surfaces in question are horizontal)
D - Data links
E - Contour lines only (no other characters in the name); EC has contour lines with text labels for the elevations (no other characters in the name). Neither of these layers follows the rules for longer layer names.
H - Holes or sockets in a 3D surface (may be used with plan layers if the surfaces in question are horizontal)
L - Labels (text) for individual views or paper drawings. LVIEWS may be unclear. That layer contains a circle showing the locations of vantage points for prepared views (with the 0,0,0 point always being the aim point). Thus, invoking the AutoCAD VIEW command to call up stored views requires consulting this layer (and at least a few plan layers) to understand the orientation of the stored views. (C or CL will be appended to view names to indicate close-up views.) Note that the layers beginning with L do not follow that rules for layer names explained below.
M - Modeled (3D) surfaces
N - Annotation links; N plus one digit. There is no meaning to the digit; there are too many notes to place on a single layer; so there are multiple annotation layers. (The layer NARROW, with no other characters, contains a north arrow and the letter N only)
P - Plan, 2D-only drawing (lines, not surfaces)
The distinction between model layers and plan layers is critical. Model layers contain 3D elements --surfaces, whether vertical or horizontal. Plan layers contain only lines at an arbitrary elevation.
Data links and annotation links are icons with numbers and lines to indicate the point or area of interest.
Cracks and holes may apply to plan and/or model layers depending on the surfaces affected.
Labels are for printing out plans.
Character Two: "in-situness"
H - Hypothetical material that is uncontested
I - In situ, undisturbed at point of original use
J - In situ, undisturbed at point of last but not original use
K - In situ, disturbed at point of original use by natural disaster
L - In situ, disturbed at point of original use by man-made action
M - In situ, disturbed at point of original use by natural events subsequent to abandonment
N - In situ, disturbed at point of last but not original use by natural disaster
O - In situ, disturbed at point of last but not original use by man-made action
P - In situ, disturbed at point of last but not original use by natural events subsequent to abandonment
S - Natural bedrock
T - Trimmed bedrock
Z - Not relevant
Character Three: the general type of the finding area, such as a public area, a domestic area, a military area, and so on
M - Military
P - Public (intended to be a very general category)
R - Religious (sanctuary, shrine, etc.)
Character Four: the specific part of the area
A - Area, a general designation
C - Courtyard
E - Entrance
F - Fortification
R - Road or street
S - Sanctuary
X - General, unstated
Z - Not applicable
Examples: Using MF as the third and fourth characters of a layer name indicates a military fortification; PR a road in a public area.
Characters Five and Six: usage (general and specific respectively). The first of the two letters signifies a broad category -- e.g., wall, stair, or pavement for a structure; the following character narrows the range of the first -- e.g., retaining, foundation, or surrounding for wall.
Character five, general use:
P - Pavement/floor
S - Stair
W - Wall
X - General
Z - Not applicable
Character Six, specific use, may take on different meanings according to character five:
B - Base
F - Foundation
J - Joint
P - Paving block
R - Retaining
S - Step (including riser and tread) for stair, surrounding for a wall
U - Uncertain, indication that the specific usage is uncertain
V - Veneer
X - General
Z - Not applicable
Examples: Using MFWS as the third through sixth characters of a layer name indicates a surrounding wall of a military fortification; RESS a step of a stair in a religious entry.
Characters Seven and Eight: material. Once again, a general category is given by the first of the two characters and a more specific one by the second.
Character seven, general material:
B - Building stone (cut or carefully shaped)
M - Metal
R - Rough stone (used without careful shaping)
X - Bedrock
Z - Not applicable
Character eight, specific material:
I - Iron
L - Limestone
O - Poros
P - Pentelic marble
X - General
Z - Not applicable
The following 5 characters (nine through thirteen) indicate a starting date for the material in question, with a beginning negative (in place of a leading zero) to indicate a date B.C.E. Dates are often conventional, not intended to be taken as literal accurate-to-the-year indicators. Consulting the Eiteljorg volume (1994) is recommended for full discussions of the dates of construction and destruction in this area.
The following 5 characters (fourteen through eighteen) indicate an ending date for the material in question, with a beginning negative (in place of a leading zero) to indicate a date B.C.E. A date of 09000 here indicates something still in place and now taken to be part of the modern environment. Dates are often conventional, not intended to be taken as literal accurate-to-the-year indicators. Consulting the Eiteljorg volume (1994) is recommended for full discussions of the dates of construction and destruction in this area.
Examples: PIREWVBO-0489-0478 = Plan version, in situ material in a religious entrance, wall veneer of cut-stone poros masonry, built in 489 B.C.E. and replaced in 478 B.C.E.
MMMFWSRL-120009000 = Modeled version, in situ but disturbed by natural events subsequent to abandonment, military fortification surrounding wall, made of roughly-shaped limestone, erected in 1200 B.C.E. and still standing.
A data table called OPlayers (as both OPlayersFP5 and OplayersTXT files -- the latter tab-delimited) contains information about actual layers in the model. It was constructed by Eiteljorg in the mid-1990s (in MS Access 95 and Access 97 and then in FileMaker 5.0 and 6.0 with tab-delimited ASCII files used as export/import format for moving data from Access to FileMaker) and finished in December of 2003. Work on this was done entirely by Eiteljorg. The table presents all layer names beginning with M, C, H, D, L, E, or N so that a user of the model may determine the nature of the material shown on the layer in question. Layer names beginning with P (plan-only layers showing the material modeled on layers beginning with M) are not included in the data table. The names may be parsed by comparing them to names beginning with M or by using the description of the layer-naming system provided above.
The system for naming layers is very rigorous and is explained above, but this table shows the actual layers made and used.
As implied above, some names do not fit the system. Layer E holds only elevation contour lines. Layer EC contains only the labels for those contour lines. (No other layers begin with E.) Layers beginning with L are labels and are named in self-explanatory ways, though LVIEWS may be unclear. That layer contains a circle showing the locations of vantage points for prepared views (with the 0,0,0 point always being the aim point). Thus, invoking the AutoCAD VIEW command to call up stored views requires consulting this layer (and at least a few plan layers for orientation) to understand the orientation of the stored views. (C or CL will be appended to view names to indicate close-up views.)
Layers beginning with N (plus a digit) contain annotation icons (see below). There are several such layers, but the names are not meaningful; the digit has no importance. There are simply several layers to prevent overlap of icons.
The layer Z is an empty layer that can confidently be used as the current layer in a program like AutoCAD. It will always be empty and therefore has no affect on any view when it is made the current layer. (Those who understand the way AutoCAD treats layers will understand the value of such a layer.)
Layer 0 is AutoCAD's default layer and cannot be removed. The copyright statement is on that layer and should show on opening the model.
Some other layers have been created by AutoCAD and cannot be removed. They are ACADASE, AME_FRZ, and ASHADE. Those layers contain no model entities.

Documentation of OPlayers Table below.
This table was created by Eiteljorg in Access 95, migrated to Access 97 format and then transferred to Filemaker (4.0) via tab-delimited export files. It was then migrated to the 5.0 format (which is used by version 6.0 as well). It was first created in the mid-1990s and completed in December, 2003.
The table uses the standard ASCII character set.
