GRA NPBUF ——— Sets maximum number of instructions per path (PostScript) 

SYNTAX

GRA NPBUF max_num

ARGUMENTS

max_num    integer greater than 10, defining the maximum number of instructions contained in a path (default 1200).

DESCRIPTION

Defines the maximum number of graphics instructions managed for PostScript in a path, i.e.: in the device's temporary graphics buffer.

Every system has a maximum limit for the number of graphics instructions contained in one path. To optimize functioning, set the max_num value closest to this limit.

To identify the limit value, refer to the hardware documentation supplied by the manufacturer.
 

GRA ODVC ——— Manages serial port configuration 

SYNTAX

perm_flg   flag which can assume the following values: 
  • 0 — temporary configuration 
  • 1 — permanent configuration (default). 

DESCRIPTION

Switches On/Off automatic serial port configuration for output devices (plotters and printers).

It may be useful to switch Off this function if the configuration of the device in question does not correspond to that envisaged.

If automatic configuration is On, you can manage the serial port parameters: the baud rate, parity, number of data bits, stop bits, the timeout period and the permanence of the configuration.

The code without arguments is equivalent to:

GRA ODVC ON 9600 0 8 1 20 1.

GRA ODVSC ——— Defines output device closing string 

SYNTAX

GRA ODVSC string | @name

ARGUMENTS


 
string    string transmitted to the device at closure.
@name    name of the file containing the strings to be transmitted to the device at its closure.
 

DESCRIPTION

Defines a string of characters to be transmitted to the output device (plotter) at its closure (only for devices which have this function: for details on how to use this parameter, refer to the documentation about the device).

You can include special characters in the string in symbol form, as follows:

  • {CR} "carriage return" character
  • {LF} "line feed" character
  • {CL} "carriage return and line feed" character
  • {nn} character represented by ASCII value nn.
    • These notations are completely converted into the corresponding characters.

    Where allowed by the device used, you can use a closing file, by placing the character @ before the name of the file; the latter is opened and transmitted to the device line by line in place of the string.

    GRA ODVT  ——— Defines type of output format (device) used 

    SYNTAX

    GRA ODVT output_type

    ARGUMENTS

     
    output_type  mnemonic identifier for type of graphic output format. The default depends on the installation configuration: it is usually HP-GL/2.
     

    DESCRIPTION

     

    Allows you to define the type of format to be used for the graphics output.

    If you indicate an output which is not allowed, an error indication appears.

    If you do not specify the type of format, the program always assigns a default type, depending on the installation configuration. The mnemonic identifiers for the various devices appear at the end of this description.

    Note: the definition of the type of format must precede the other configuration commands for the same device in the initialization file. The same applies if you use the code as an option in the run string.

    Wherever the hardware/software configuration does not allow you a choice, the default type is already correct, therefore, the command  has no impact.
     

    See also:  ODEV 

    The following tables show the values allowed for types of output device/format:

  • BGL
  • CALCOMP
  • HP-GL

    GRA P1P2 ——— Defines reference points P1 and P2 

    SYNTAX

    GRA P1P2 x1 y1 x2 y2

    ARGUMENTS

    x1, y1     integers which define the coordinates of point P1.
    x2, y2    integers which define the coordinates of point P2.

    DESCRIPTION

    Redefines the position of points P1 and P2 and so also the working dimensions of the sheet for plotting (in device units of measure).

    For the plotters which manage it, the frame step (in device units of measure) remains fixed. Each plotter has its own specific frame step linked to the default values of P1 and P2,obtained with the plotter on line and GRA SHP1P2.

    You may have to set a frame step when plotting with framing on file (plotter off line). In this case, the program cannot poll the plotter for the specific frame step. The values of P1 and P2 to be specified are those obtained as above.

    GRA PWIDTH ——— Defines thickness to be associated to pensline widthline weight 

    SYNTAX

    GRA PWIDTH {pen thickness [unit]}

    ARGUMENTS

    pen    integer which identifies the colour (pen) to which the thickness sp must be associated; values allowed -1:256.
    thickness   real number which identifies the thickness associated to the colour pen; values allowed -256:256;
    unit   unit of measure; values allowed and meanings:
    • MM — thickness is expressed in millimeters (default)
    • CM — thickness is expressed in centimeters
    • IN — thickness is expressed in inches.

    Default:0. No thickness.

    DESCRIPTION

    For each colour index (0:255), allows you to define a thickness (line weight or line width) in various forms.

    If pen=-1 the thickness specified is assigned to the entire colour table.

    The presence of unit indicates that you must multiply the thickness value by 1 (MM), by 10 (CM) or 25.4 (IN).

    If thickness < 0, irrespective of the thickness management mode (GRA MWIDTH) is considered to be in units of the device.

    If thickness > 0 and the thickness management mode is in units of the device (GRA MWIDTH 1), only the whole part of the number expressing the thickness in units of the device is considered.

    Thickness management may not be available on all devices.

    DESCRIPTION

    Allows you to define the library to be used to resolve the occurrences of symbols present in the drawing.

    The possibility of changing the current symbol library may prove very useful when printing files containing symbols which, although maintaining the same name, assume a different graphic appearance in different contexts.

    For example, the same drawing may contain symbols to be printed according to European standards and American standards: this option allows you to print both versions of the drawing by simply specifying the two different libraries, without changing the drawing file.

    ROR ——— Manages relocation of drawing origin on plotter 

    SYNTAX

    ROR dx dy

    or:

    GRA RORIG dx dy [u_measure]

    ARGUMENTS

    dx    real number defining the shift in cm along the x-axis.
    dy   real number defining the shift in cm along the y-axis
    u_measure    unit of measure for the shift; values allowed and meanings: 
    • MM millimeters (default);
    • CM centimeters.

      • DESCRIPTION

      Allows you to shift the drawing origin on the plotter before plotting. The current position of the origin depends on the type of plotter: on relative-motion plotters (BGL, Calcomp) it remains at the point occupied by the pen at the end of the previous drawing, whilst on absolute-motion plotters (HP) it remains fixed at the bottom left-hand point of the sheet or at the center of the sheet. Set the shift with great care, since an error may cause the drawing to be off the edges of the sheet or make the drawing previous drawings.

      You must use this code when you rotate the drawing on the Calcomp and BGL plotter, since a 90 ° rotation for Calcomp and BGL moves the drawing from the first to the second frames.

      Relocating the origin is one way of merging two or more drawings on the same sheet, this being an alternative to the mode activated with run option -COM: although the latter is preferable.

      ry real number which sets the resolution along the y-axis
       
      • with RPL: in dots per centimetre if > 0 
      • with GRA ODVR: in dots per millimetre 
      DPI  constrains the unit of measure for the resolution in dots per inch; if you do not specify this, the resolution is considered 
       
      • with RPL: in dots per centimetre if > 0 
      • with GRA ODVR: in dots per millimetre 

      DESCRIPTION

      For devices which allow different resolutions, defines values other than the default. The default values are determined automatically where possible, or preset according to the output device family.

      CALCOMP PCL format

      Default is 40 40. Adjust the resolution if the plotter used has a different configuration.

      HP-GL and HP-GL/2 format

      Default is 40 40.

      Raster format

    • The program sets the values allowed on the basis of the GRA ODVT value

      TOL  ——— Defines tolerance parameters 

      SYNTAX

      TOL cenline_dist char_height tol_dist

      ARGUMENTS

      cenline_dist    Character height multiplication factor for dimensions which identifies the distance to be set in the drawing between the horizontal line through the center of the tolerances and the horizontal line through the center of the dimension texts
      char_height    Character height multiplication factor for dimensions which identifies the character height to be used when drawing the tolerances
      tol_dist    Character height multiplication factor for dimensions which identifies the distance to be set when drawing the tolerances.
      Default
       
      cenline_dist=0 
      char_height=0 
      tol_dist=0.2 

      DESCRIPTION

      Allows you to define the tolerance construction parameters.


       

      UNI  ——— Specifies UNI table 

      SYNTAX

      UNI pathname

      ARGUMENTS

      pathname  pathname of the file containing a UNI table.

      DESCRIPTION

      Allows you to automatically attribute to any dimension which represents the diameter of a hole or a shaft the tolerances defined in accordance with UNI standards (UNI 7218-73: selecting tolerance zones for mating parts recommended to limit the number of tools, test gauges and measuring instruments). The dimension format which you define must contain indications of the position and quality of the tolerance (e.g.: FO "{m}a9", FO "{m}JS10", etc.); you can use the UNI command at any time to add the tolerances contained in the UNI table from the program to all dimensions defined in this way. Any tolerances which you specified are substituted by those shown in the table

      VNO  ——— Defines the unit normal for the view (Eureka) 

      SYNTAX

      VNO nox noy noz

      ARGUMENTS

      nox  component in direction x of the world reference system of the unit normal for the view
      noy component in direction xy of the world reference system of the unit normal for the view
      noz  component in direction z of the world reference system of the unit normal for the view.
       

      Default
       
      nox=0 
      noy=1 
      noz=0 

      DESCRIPTION

      Allows you to define the components of the unit normal of the xy plane of the reference system of the current view for "e3" files. This is a z-axis unit vector of the said reference system; given that the latter is a right-hand orthonormal triplet, it is completely defined once you have also defined the y unit vector of the reference system (with VUP).
       
      See also:  VUP 

      VUP  ——— Defines the unit normal for the view (Eureka) 

      SYNTAX

      VUP upx upy upz

      ARGUMENTS

      upx  component in direction x of the world reference system of the y-axis unit vector of the reference system of the view 
      upy component in direction xy of the world reference system of the y-axis unit vector of the reference system of the view
      upz  component in direction z of the world reference system of the y-axis unit vector of the reference system of the view .
       

      Default
       
      upx =0 
      upy =1 
      upz =0 

      DESCRIPTION

      Allows you to define the components of the unit vector which indicates the direction from the bottom to the top of the view, i.e.: of the y-axis unit vector of the reference system of the current view for "e3" files. Since it is a right-hand orthonormal triplet, the said reference system is completely defined once you have also defined the z unit vector of the reference system (with VON).
