Introduction

This process creates an isometric view of perimeters and strings.

Files, Fields and Parameters

Input Files

Name	Description	I/O Status	Required	Type
PROTO	Prototype plot file. Only the plot area data is used. Any scaling and data ranges (XMIN, XMAX etc ) are ignored.	Input	Yes	Plot Prototype
PERIMIN	Perimeter input file	Input	Yes	String

Output Files

Name	I/O Status	Required	Type	Description
PLOT	Output	Yes	Plot	Output plot file

Parameters

Name	Description	Required	Default	Range	Values
PXMIN	X value of left-hand side of region to be plotted.	Yes	Undefined	Undefined	Undefined
PXMAX	X value of right-hand side of region to be plotted.	Yes	Undefined	Undefined	Undefined
PYMIN	Y value of front of region to be plotted.	Yes	Undefined	Undefined	Undefined
PYMAX	Y value of back of region to be plotted.	Yes	Undefined	Undefined	Undefined
PZMIN	Z value of bottom of region to be plotted.	Yes	Undefined	Undefined	Undefined
PZMAX	Z value of top of region to be plotted.	Yes	Undefined	Undefined	Undefined
ROTATE	The rotation angle in degrees horizontally of the viewpoint, clockwise from the data Y axis (45).	No	45	0,360	Undefined
ELEVATE	The rotation angle in degrees vertically of the viewpoint, upwards from data X-Y plane (45).	No	45	-90,90	Undefined
CHARSIZE	Character size in millimetres (4).	No	4	Undefined	Undefined
ASPRATIO	Aspect ratio, width / ht. for chars (0.9).	No	0.9	Undefined	Undefined
	Colour [as 'pen' number] for plot (1).	No	1	Undefined	Undefined

Notes

Scaling is fully automatic in this process.

Example

This 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
2
14000
60000
15000
60000

-50
150
Y

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	Solution
>>> 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.

>>> NVALID 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.
