See this process in the Command Table.

Process Overview

This command can be used to project points vertically onto a nominated wireframe surface.

Note: The input file must be sorted on the X coordinate.

Input Files

Name	Description	I/O Status	Required	Type
IN	Input file to be intersected. Must contain fields X , Y , Z. Must be sorted on X.	Input	Yes	Undefined
WIRETR	Input wireframe triangle file.	Input	Yes	Wireframe Triangle
WIREPT	Input wireframe point file.	Input	Yes	Wireframe Points

Output Files

Name	I/O Status	Required	Type	Description
OUT	Output	Yes	Undefined	Output file with additional elevation field.

Fields

Name	Description	Source	Required	Type	Default
X	Name of intersection X field in IN.	IN	Yes	Numeric	Undefined
Y	Name of intersection Y field in IN.	IN	Yes	Numeric	Undefined
Z	Name of output elevation field in OUT.	OUT	Yes	Numeric	Undefined

Parameters

Name	Description	Required	Default	Range	Values
KEEP	To carry through points not intersected by any triangle, with Z	No	0	0,1	0,1

Error and Warning Messages

Message	Description
>>> ERR 120 <<< (y) in TRIPOI	Missing or invalid file (y is the file number).
>>> ERR 121 <<< (y) in TRIPOI	Missing or invalid fields (y is the file number).
>>> TOO MANY FIELD <<< >>> ERR 122 <<< (y) in TRIPOI	Too many fields in the output file. Note: Maximum fields = 256
>>> NO DATA IN INPUT FILE <<< >>> ERR 136 <<< (y) in TRIPOI	No data in the input file &IN.
>>> MISSING OR ALPHA FIELD (S) IN MODEL PROTOTYPE <<< >>> ERR 142 <<< (y) in TRIPOI	Either the input model does not include the required thirteen model fields, or the fields are alpha rather than numeric.
>>> MISSING OR ALPHA FIELD (S) IN WIREPT FILE <<< >>> ERR 145 <<< (y) in TRIPOI	Either the input wireframe points file does not include the required four numeric fields (XP,YP,ZP,PID), or the fields are alpha rather than numeric.
>>> MISSING OR ALPHA FIELD (S) IN WIRETR FILE <<< >>> ERR 146 <<< (y) in TRIPOI	Either the input wireframe triangle file does not include the required four numeric fields (PID1,PID2,PID3,TRIANGLE), or the fields are alpha rather than numeric.
