General

This is a description of the file format of OCAD 12 files.

Be aware that this is an internal format and may change in future versions.

Data types used

OCAD is written in 64-bit Delphi and this description uses the names for the data types as they appear in Delphi. However the same data types are available in other development systems like C++.

Integer 32-bit signed integer
Cardinal 32-bit unsigned integer
SmallInt 16-bit signed integer
Word 16-bit unsigned integer
WordBool 16-bit boolean
String[x]

Widestring. The first byte contains the number of characters followed by the characters. The string is not zero-terminated. The maximum number of characters is x. It occupies x + 1 bytes in the file.

Double 64-bit floating point number
TDPoly A special data type (64-bit) used for all coordinates and text. It is defined as

TDPoly = record
x, y: integer;
end;

The lowest 8 Bits are used to mark special points:

Marks for the x-coordinate:
1: this point is the first bezier curve point
2: this point is the second bezier curve point
4: for double lines: there is no left line between this point and the next point
8: this point is a area border line or a virtual line gap

Marks for y-coordinate:
1: this point is a corner point
2: this point is the first point of a hole in an area
4: for double lines: there is no right line between this point and the next point
8: this point is a dash point

The upper 24 bits contain the coordinate value measured in units of 0.01 mm.

Note: all file positions are in bytes starting from the beginning of the file.

File Header

OCAD files start with a file header.

TFileHeader = record              // size = 60 Byte 
  OCADMark: SmallInt;             // 3245 (hex 0cad)
  FileType: Byte;                 // file type (0: normal map, 1: course setting project, 8: file is saved in Server) 
  FileStatus: Byte;               // not used
  Version: SmallInt;              // 12
  Subversion: Byte;               // number of subversion (0 for 12.0, 1 for 12.1 etc.)
  SubSubversion: Byte;            // number of subsubversion (0 for 12.0.0, 1 for 12.0.1) 
  FirstSymbolIndexBlk: Cardinal;  // file position of the first symbol index block
  ObjectIndexBlock: Cardinal;     // file position of the object index block -> TObjectIndexBlock    // max 65536 * 256 objects 
  OfflineSyncSerial: integer;     // serialNumber for offline work in Server mode
  CurrentFileVersion: integer;    // file version for OCAD version
  Internal: Cardinal;             // 
  Internal: Cardinal;             //
  FirstStringIndexBlk: Cardinal;  // file position of the first string index block
  FileNamePos: Cardinal;          // file position of the file name, used for temporary files only
  FileNameSize: Cardinal;         // size of the file name, used for temporary files only
  Internal: Cardinal;             // 
  Res1: Cardinal;                 // not used
  Res2: Cardinal;                 // not used
  MrStartBlockPosition: Cardinal; // file position of mulitple represention index block

Symbols

Each Symbol Index Block contains the position of the next Symbol Index Block and the file position of 256 symbols.

TSymbolIndexBlock= record        // Size: 1028 Bytes
  NextSymbolIndexBlock: integer;
  SymbolPosition: array[0..255] of integer;
end;

Base Symbol

The different types of symbols are defined in different structures. There is an abstract type TBaseSym, which contains the fields common to all symbols types. It is used for programming reasons, but does not exist in real OCAD files.

TBaseSym = packed record
  Size: integer;                // Size of the symbol in bytes. This  depends on the type. Coordinates following the symbol are included.
  SymNum: integer;              // Symbol number. This is 1000 times the symbol number. 
                                // for example:
                                //   203.145 is stored as 203145
  Otp: byte;                    // Object type
                                //   1: Point symbol
                                //   2: Line symbol or Line text symbol
                                //   3: Area symbol
                                //   4: Text symbol
                                //   6: Line text symbol
                                //   7: Rectangle symbol
  Flags: byte;                  // 1: rotatable symbol (not oriented to north)
                                // 4: belongs to favorites
  Selected: boolean;            // Symbol is selected in the symbol box
  Status: byte;                 // Status of the symbol
                                //   0: Normal
                                //   1: Protected
                                //   2: Hidden
                                // AND 16: selected
  PreferredDrawingTool: byte;   // Preferred drawing tool
                                //   0: off
                                //   1: Curve mode
                                //   2: Ellipse mode
                                //   3: Circle mode
                                //   4: Rectangular line mode
                                //   5: Rectangular area mode

                                //   1: course symbol

                                //   a combination of the flags
                                //   64: available in column B
                                //   32: available in column C
                                //   16: available in column D

Point Symbol

Point symbols are stored with this structure:

TPointSym = packed record
  Size: integer;                         // see TBaseSym
  SymNum: integer;                       // see TBaseSym
  Otp: byte;                             // 1
  Flags: byte;                           // see TBaseSym
  Selected: boolean;                     // see TBaseSym
  Status: byte;                          // see TBaseSym
  PreferredDrawingTool: byte;            // see TBaseSym
  CsMode: byte;                          // see TBaseSym
  CsObjType: byte;                       // see TBaseSym
  CsCDFlags: byte;                       // see TBaseSym
  Extent: integer;                       // see TBaseSym
  FilePos: cardinal;                     // see TBaseSym
  notUsed1: Byte;            
  notUsed2: Byte;            
  nColors: SmallInt;                     // see TBaseSym
  Colors: array[0..13] of SmallInt;      // see TBaseSym
  Description: array[0..63] of char;     // see TBaseSym
  IconBits: array[0..483] of byte;       // see TBaseSym
  SymbolTreeGroup: Array[0..63] of Word; // see TBaseSym
  DataSize: word;                        // number of coordinates (each 8 bytes) which follow this structure, each object header
                                         // counts as 2 Coordinates (16 bytes)
  Reserved: SmallInt;
end;


After this structure follow the symbol elements which build that Point symbol. These symbol elements are stored in the following structure. Note that these symbol elements are stored in a different way than ordinary map objects.

TSymElt = record
  stType: SmallInt;                   // type of the symbol element
                                      //   1: line
                                      //   2: area
                                      //   3: circle
                                      //   4: dot (filled circle)
  stFlags: word;                      // Flags
                                      //   1: line with round ends
  stColor: SmallInt;                  // color of the object. This is the number which appears in
                                      // the colors dialog box
  stLineWidth: SmallInt;              // line width for lines and circles unit 0.01 mm
  stDiameter: SmallInt;               // Diameter for circles and dots. The line width is included
                                      // one time in this dimension for circles.
  stnPoly: SmallInt;                  // number of coordinates
  stRes1: SmallInt;                   // Not used
  stRes2: SmallInt;                   // Not used
  stPoly: array[0..32767] of TPoint;  // coordinates of the symbol element
end;

If there are several objects, they just follow each other (only the coordinates used are stored). To determine the number of objects the DataSize variable must be used.

Line Symbol

Line symbols are stored in the following structure. In the explanation the terms used in the Line Symbol dialog box are shown.

Parameter Strings

The Parameter Strings contain all the information about the setup structure, background maps,course setting and database connection.

Similar to the symbols and objects there are String Index Blocks which contain the basic information for 256 Parameter Strings and the file position of the strings.

TStringIndexBlock contains the basic information for 256 strings

TStringIndexBlock = record
  NextIndexBlock: integer;            // file position of the next StringIndexBlock, 0 if this is the last StringIndexBlock
  Table: array[0..255] of TStringIndex;
end;

TStIndex contains the basic information for 1 string:

TStringIndex = packed record
  Pos: integer;                       // file position of string
  Len: integer;                       // length reversed for the string
  RecType: integer;                   // string typ number, if < 0 then deleted string
  ObjIndex: integer;                  // index of the object
end;

StringIndexBlk in the FileHeader points to the first StringIndexBlock.

The strings (null terminated) have the following structure:

  • first field: all characters until the first tab (character 9). The first field can be missing (the string starts with a tab).
  • tab (character 9)
  • code: this is the first character after the tab
  • value: all characters until the next tab
  • tab
  • code
  • value
  • ...

Some of String Types (number < 1000) may have multiple instances of the same type. They have to be stored as lists.
