INTRODUCTION With current release of ADOT CADD STANDARDS further steps have been taken to increase uniformity in design concept presentation and to streamline the task of design file cre- ation. Since the whole standard book as well as several i- tems in the cell libraries have been redefined, the current edition invalidates all standard data (book,cell libraries) released or printed prior to MAY-15-1990. New set of stan- dards consists of five volumes: - SPECIFICATIONS general specifications, master index - GRAPHICS VOL 1 general graphic symbols, mapping, index - GRAPHICS VOL 2 right of way, highway plans, index - GRAPHICS VOL 3 structures section symbols, index - GRAPHICS VOL 4 traffic operations,traffic studies, index Internal organization of every volume basically follows the same pattern: volume contents (general), volume or section specific specifications, list of graphic items (sequential order), graphic items definitions, index. In multisection volumes such as vol. 2 and vol. 4, features 2, 3 and 4 re- occur in each section listed. Logical grouping of the gra- phic items vary from volume to volume ; graph. vol. 1 items are grouped by level and by type within each level, the o- ther volumes' graphic items are grouped by type and by le- vel if applicable. All volumes should be considered as the integral parts of one entity and should never be used sepa- rately as standalone, self-sufficient documents.All graphic and non-graphic items defined in the section specific volu- mes supersede on item by item basis all corresponding items from GRAPHICS VOL. 1 and SPECIFICATIONS volume in case when project is done in or for specific ADOT section. If the de- sired item or specification is not defined in the applicab- le section specific volume corresponding item from GRAPHICS VOL. 1 or SPECIFICATIONS volume should be used. Consultants under contract with ADOT should check with specific section for project special requirements and up to date specifica- tions before the project work begins. Master index contains alphabetically sorted references to all graphic items defi- ned in any of the volumes and each item has up to four ent- ries with first word of the item description different for each entry. In addition to master index each volume has its own volume index for faster and more efficient searches. First digit of the page number refers to the volume number (0-MMM.mm SPECIFICATIONS, 1-MMM.mm GRAPHICS VOL. 1 etc...), LIBRARY - parent cell library name for given item, CELL - cell name (none in not a cell item). Several cell libraries support the graphics defined in the STANDARDS and these li- braries are distributed by ADOT CADD SYSTEM SERVICES accor- ding to the cadd data acceptance and release rules stated in SPECIFICATIONS volume. CADD STANDARDS books and updates are distributed by ADOT ENGINEERING RECORDS either over the counter or through the mailing lists of registered users. CADD DATA ACCEPTANCE AND RELEASE RULES All CADD data submitted to or released from ADOT shall be in full compliance with following specifications: FORMAT The data shall be in standard InterGraph format, free of corrupted elements, with InterGraph type 9 headers (.dgn files) or type 5 headers (.cel files) and valid end of file markers. ADOT will not accept or release data in any other format, e.g. SIF, IGES, DXF, et cetera... If the data is created on a system other than InterGraph, it shall be the responsibility of the submittor to translate data to InterGraph IGDS format. FILE PARAMETERS Working units and global origin shall conform to the specifications defined in the ADOT CADD STANDARDS ( General or sections specifications ) unless explicitly requested otherwise by ADOT. GRAPHICS Graphic parameters such as level, color, weight, line code, text size, font, et cetera... shall conform to the specifications defined in the ADOT CADD STANDARDS. Unless explicitly requested otherwise by ADOT the standard InterGraph line styles (line codes) shall not be modified in any other way than patterning (cells placed end to end along a line). All necessary cells and fonts are provided by ADOT in cell and font libraries to insure full conformity with ADOT CADD STANDARDS. Unless explicitly requested otherwise by ADOT all graphic files shall be self-contained (file must stand on its own) All relevant graphics from external [reference] files must be copied into master design file and then reference files must be detached. Reference file attachment shall be performed using upper case characters on a command line. File extension and logical name shall be present in the reference file specification. The design file shall contain no more then one plan sheet or map per file. The file name and date the sheet was plotted shall appear in the lower left corner of the plan sheet (refer to the TIME cell or plan sheet cells for location and graphic definitions). DISTRIBUTION The basic means for CADD data transportation shall be standard 1/2", 9 track reel to reel computer tape with density of 1600 [800,6250] BPI (bytes per inch). Data shall be placed on tape using VAX/VMS BACKUP command. Optionally the 1.2 Mb high density 5.25 inch MS/DOS formatted floppy dikettes can be used but following restrictions shall be applied: - file must be small enough to fit entirely on one floppy - data shall be placed on floppy using MS/DOS COPY command - compression utilities (such as PCTOOLS) or MS/DOS BACKUP command shall not be used - maximum of 10 floppies of data per project shall be used Data not complying with the above mentioned restrictions shall be placed on standard magnetic tape only (refer to the tape specification). The media for the data shall be provided by the requestor. There will be a 100 US dollar charge for each megabyte of data requested unless the requestor is under contract with ADOT. No guaratee acompanies ADOT CADD data other than the fact that released data is usable on VAX based InterGraph workstations at ADOT. GENERAL SPECIFICATIONS All sections' specific specifications supersede following GENERAL SPECIFICATIONS on item by item basis. Section spe- cific and GENERAL SPECIFICATIONS complement each other and none of them should be considered as self-sufficient sepa- rate set of CADD specifications. FILE PARAMETERS - file organization: sequential - file headers: InterGraph type 9 (graphic file) InterGraph type 5 (cell library) - graphic items: all valid InterGraph elements - InterGraph end of file marker WORKING UNITS Working Area 4294967 FT Subunits/Master Unit 10 Positional Units/Subunit 100 GLOBAL ORIGIN The global origin shall be set in the precise center of the design plane [cube (3-D)] unless explicitly requested otherwise by ADOT. Suggested procedure The best and always precise setup of the global origin in the center of the design plane [cube (3-D)] can be accom- plished by setting GOXUOR, GOYUOR [,GOZUOR (3-D)] TCB vari- ables equal to 0 (zero) and writing them into type 9 (de- sign file header). Following example user command will set up global origin in the precise center of the design plane, regardless of work- ing units setup, if executed while in graphics. ;gocen.ucm ; SET GOXUOR=0 SET GOYUOR=0 SET GOZUOR=0 ;if 3D file CMD FILDGN ;save in type 9 header END TEXT The following general text parameters shall be used on all sheets at scale 1"=100' unless: - specified otherwise in the sections' specifications - specified otherwise in the item's standard definition - preset within a cell - explicitly requested otherwise by ADOT For the sheets at different scale TX and LS values shall be modified accordingly to insure text size consistency. FT=23 (proportional, general text) FT=24 (nonproportional, tabularized text) TX=15 (existing items) (0.1500" on full size plots) TX=17.5 (new items) (0.1750" on full size plots) LS=7.5 (existing items) (0.0750" on full size plots) LS=8.75 (new items) (0.0875" on full size plots) WT=2 (existing items) WT=4 (new items) LC=0 (all) CO=LV (color shall be numerically equal to the level on which text is placed; for correct values refer to ADOT CADD STANDARDS SPECIFICATIONS - LEVELS) The following text sizes for special items such as headers et cetera... shall be used on all sheets unless explicitly requested otherwise by ADOT. full size scale 1:100 Leroy 0.26 " TX=26 290 0.22 " TX=22 240 0.175" TX=17.5 200 0.15 " TX=15 175 0.10 " TX=10 100 Only fonts (graphic definitions of characters and font nu- mbers) from ADOT font library shall be used. For fonts de- finitions refer to ADOT CADD STANDARDS - FONTS. Following fonts constitute the ADOT font library: Font 1 vertical proportional - general text,headers,titles Font 7 old english - special headers,titles,nontechnical Font 9 vertical nonproportional - tabularized text,general Font 23 slanted proportional - general slanted text Font 24 slanted nonproportional - tabularized slanted text Font 30 swiss bold - details,traffic signs,special headers Font 42 outline proportional - special graphics Font 126 symbol font - special symbols,(automatic dimens.) Font 127 fast font - slashed zero required in text LEVEL [COLOR] DESIGNATIONS Unless explicitly specified otherwise by ADOT color shall be numerically equal to the level of the graphic item (CO=LV).
