Values From Fields

To control a certain field, the label FIELD is analyzed in the configuration. A colon follows, than the field name, from where the value is read. Subsequently a default value can be entered. This will be used if no field value exists. Additional data is possible.

FIELD: Fieldname:Default

FIELD: Fieldname:Default[:Prefix[:Postfix[:TRIM|<SPLITINFO>|REMFORMAT[:Comma[:Thousand[:Prec]]]]]]]

The values in square brackets are optional.

_img2

In the example, the value for the block name will be taken from the field BLOCK. In the GIS output data this means that in the attribute table of the accessed feature class a field exists with the label BLOCK. If for the respective feature no field value will be found in the field BLOCK or there is no entry, GN1 (default) will be used.

•Field
Is at the beginning of the expression.

•Fieldname
The field name from the feature class or a joined table.

•Default
If the field name is not found, or if the field value is zero, default is used.

Example:FIELD:HOEHE:NH
cad_exp3
The further values are optional.

•Prefix (optional)
This entry is prefixed to the value.
Example: FIELD:PKTNR:(NoNr):%%U (Underscore in AutoCAD)
Example: FIELD:HEIGHT:NH:Height=

cad_exp1

•Postfix (optional)
This entry is postfixed after the value.
Example: FIELD:HEIGHT:NH:Height=:m

cad_exp4

•TRIM, <SPLITINFO> or REMFORMAT (optional)

•TRIM
Literal. Removes whitespace characters (spaces, tabs, etc.) before and after the value.

•<SPLITINFO>
= SPLIT,<SEPARATOR>,<SPLITINDEX>
<SEPARATOR>
= "<TEXTSTRING>"
<SPLITINDEX> := <INTEGERVALUE>

•REMFORMAT
Literal. Removes '<' and associated '>' and everything that is in between.
Example: FIELD:GNR:(NoNr):::SPLIT,"/",0

•Comma (optional)
Comma = comma sign. Only if there is a deviation from the country setting and as indicator for converting into double value.

•Thousand (optional)
Thousands sign. Only if a deviation from the country setting of the system is wanted.

•Prec
Number of the decimal places. Valid are values from 0 – 16.

Example: FIELD:HEIGHT:0.0::::::2
Means: Read value from the field MyDouble. If the field does not exist, use value 0.0. Render comma and thousand sign from country setting. Number of the decimal places = 3.

cad_exp2

The value (prec) can be used only for numeric values. A combination with the other optional values such as e.g. prefix, postfix is not possible, since these options convert the numeric format into text.
