ROTATE |
The rotation angle of the direction of view, in degrees horizontally and clockwise from the data Y axis. Default (45). E.g. if model Y and X axes are parallel to North 45 = Looking North-East 225 = Looking South-West |
No |
45 |
0,360 |
Undefined |
||||||
|
ELEVATE |
The rotation angle of the direction of view, in degrees vertically from data X-Y plane. Default (30). E.g. if model Y and X axes are parallel to North 0 = Looking horizontally, along X-Y plane. +90 = Looking vertically downwards -90 = Looking vertically upwards |
No |

APPEND |
Plot append flag. If set to 1 then the new plot will be appended to the PLOT file, if it exists and is a valid plot file. N.B. Scaling is fully automatic in this process. |
No |
0 |

|
-
Scaling is completely automatic in this process, and any plot file or null prototype may be used; all that need be defined is the paper size.
-
The hidden line removal algorithm can be slow when using large data sets, so it is recommended that an initial plot with @HIDDEN set to 1 be produced to check the view parameters.
Example
!ISOTRI &PROTO(WISOPROT),&WIREPT(ZON1PT),&WIRETR(ZON1TR) &PLOT(WISOZON1)
Error and Warning Messages
|
Message |
Description |
Solution |
|
>>> ANNOT APPEND TO NON-EXISTENT OUTPUT FILE. >>> A NEW OUTPUT FILE WILL BE CREATED. |
The @APPEND parameter has been set to 1, but the specified plot file does not exist. A new file will be created to contain the new plot being produced. |
|
|
|
|
|
|
>>> ERROR - CANNOT APPEND TO PLOT FILE AS IT DOES >>> NOT CONTAIN ALL THE REQUIRED FIELDS. >>> THE PLOT FILE WILL BE OVERWRITTEN. |
The @APPEND parameter has been set to 1, the specified plot file exists but is invalid. The existing plot file will be overwritten by the new plot being produced |
|
|
|
|
|
|
>>> ERROR IN READING INPUT FILE <<< >>> ERR 121 <<< ( n) IN ISOTRI |
An error has occurred when reading the input point or triangle file e.g. one or more of the essential fields in the file is absent or of the wrong type. Fatal; the process is exited. |
