ISOPER Process

To access this process:

Enter "ISOPER" into the Command Line and press <ENTER>.
Display the Find Command screen, locate ISOPER and click Run.

See this process in the Command Table.

Process Overview

Create an isometric view of perimeters and strings.

Note: Scaling is fully automatic in this process.

Output Files

Name	I/O Status	Required	Type	Description

Example

The following example demonstrates the use of ISOPER to produce isometric plots of pit design and section perimeters.

The process SURTRI is used to build a Digital Terrain Model of the original design perimeters and WIREPE is then used to create the pit sections.

Plot the design perimeters:

!ISOPER &PROTO(PROTO), &PERIMIN(PITDESN), &PLOT(PLOT1),

@PXMIN=14000, @PXMAX=15000, @PYMIN=60000, @PYMAX=61000,

@PZMIN=-50, @PZMAX=150, @ROTATE=25, @ELEVATE=45

Build a DTM of the design perimeters:

!SURTRI &WIREPT(PT), &WIRETR(TR), &PERIMIN(PITDESN)

Generate pit section perimeters:

!WIREPE &WIREPT(PT), &WIRETR(TR), &PERIMOUT(PITSECN), @YINCR=20

14000

60000

15000

60000

-50

150

Plot the pit section perimeters:

!ISOPER &PROTO(PROTO), &PERIMIN(PITSECN), &PLOT(PLOT2),

@PXMIN=14000,@PXMAX=15000, @PYMIN=6000, @PYMAX=61000,

@PZMIN= -50,@PZMAX=150,@ROTATE=25, @ELEVATE=45.

Error and Warning Messages

Message	Description
>>> MISSING FILES <<<	One or more of the input files do not exist. Fatal; the process is exited.
>>> ATTEMPT TO OPEN PERIMETER FILE <<<	The input perimeter file can not be read by the process (e.g. it does not exist). Fatal; the process is exited.
>>> ATTEMPT TO OPEN PROTO FILE <<<	The plot prototype file can not be read by the process (e.g. it does not exist). Fatal; the process is exited.
>>> ATTEMPT TO CALL PLINIT <<<	An error occurred when initiating the graphics environment (e.g. it has failed to open the output plot file or it has failed to open the screen device). Fatal; the process is exited.
>>> ATTEMPT TO COPY DATA DEFINITION <<<	An error occurred when copying the data definition from the input prototype file to the output plot file (e.g. disk full). Fatal; the process is exited.
>>> MISSING PERIMETER FIELDS <<<	One or more of the essential perimeter fields are missing (e.g. the file specified is not a perimeter file). Fatal; the process is exited.
>>> MISSING ISOMETRIC PARAMETERS <<<	One or more of the compulsory isometric parameters are missing (e.g. ISOPER is running within a macro). Fatal; the process is exited.
>>> INVALID PLOT COORDINATES <<<	One or more of the compulsory plot coordinates are missing, incorrect or inconsistent (e.g. @XMIN > @XMAX). Fatal; the process is exited.
>>> NO MORE ROOM FOR PLOT FILE FIELDS <<<	The maximum number of 64 fields in a file has been exceeded. Fatal; the process is exited.
>>> ATTEMPT TO WRITE PLOT DATA DEFINITION <<<	An error occurred when writing the data definition of the output plot file (e.g. disk full). Fatal; the process is exited.
>>> ATTEMPT TO READ PERIMETER FILE <<<	An error occurred when reading in the perimeter file (e.g. it has corrupted or invalid data). Fatal; the process is exited.
