I am planning on getting this to the free CD (the remaped file is currently 35mb) Original model by Bob Galbraith of Computer Graphics (1991) NOTICE: This 3D drawing database (AZ-CITY.DWG) is the property of Bob Galbraith Computer Graphics and may be freely distributed, viewed, or enhanced for personal use only. Commercial use is prohibited without the notification and consent of its creator, Bob Galbraith. WARNING: This is a huge AutoCAD Release 11 file. While it database weighs in at 1.1 megs, that is only half the story, this file makes abundant use of blocks to conserve its size. It is strongly recommended that a fast 386 with at least 4 megs of memory (probably more) be used to view this file. It was created with a 25 Mhz i486 with 8 megs of memory and a 200mb 15ms hardrive. The file takes this machine 1 minute 25 seconds call up into the AutoCAD editor. INTRODUCTION: This 3D database is based on a photograph of a physical model which was created by architect Ignacio Marquina. This vivid image appeared in a book "The Mighty Aztecs" which is published by The National Geographic Society. The only other reference was a book called "The Cities of Ancient Mexico" which had a plan drawing of the recently excavated "Great Temple". Somewhere in text it was stated that wall which surrounded the ceremonial center was some 440 meters on a side. Armed with this information and eyeball, I was off to the races. It is sincerely hoped that my efforts do justice to the glory of ancient city of Tenochtitlan. Only the temples, palaces, wall and other notable structures were included. If someone wants to add some 3D people. fauna, and few graven images, be my guest. A lot of AutoCAD colors were used which could mapped for rendering outside AutoCAD. Hopefully someone with a very high powdered workstation could render or even do animated walkthru of this model. At the present time using AutoShade Renderman, I can only do single images of single structures while throwing my system page mode. AutoCAD Release 11 has a primitive shader for checking work. There are two saved views ("city & perspect") to restore. If you have a high resolution 256 color display, try setting system variable "shadedge" to 0 and evoking the shade command. In closing, it should be mentioned that the scale of the model is 1 AutoCAD unit = 1"-0". If one can put aside the hideous brutal religious rites that were practiced by the Aztecs it is obvious that these were a highly energetic and gifted people. Bob Galbraith
