Regular expressions allow you to convert several objects, such as an entire IPE section series, by a single entry.
Example
Conversion of, for example, IPE120 in Tekla to IPE 120 | Euronorm 19-57; ... | SZS in RFEM 6 should also work for all other cross-sections of the IPE cross-section series.
In order to create a conversion for the entire IPE cross-section series, the regular expression is structured as follows:
| Conversion from Tekla to RFEM 6 | Tekla | RFEM 6 |
| Regular Expression | IPE(\d+) | IPE $1 Euronorm 19-57; ... SZS |
| Cross-Section Name | IPE120 | IPE 120 Euronorm 19-57; ... SZS |
| Cross-Section Name | IPE300 | IPE 300 Euronorm 19-57; ... SZS |
For the expression (\d+), you can enter any decimal number. (IPE200, IPE300,...)
The expression $1 refers to the entered decimal number. In the following image, the regular expression has been added to the Tekla conversion table.
If two decimal numbers are used, the expression $1 refers to the first number and $2 refers to the second number. The following table shows this, using the example of the material conversion.
| Conversion from Tekla to RFEM 6 | Tekla | RFEM 6 |
| Regular Expression | C(\d+)/(\d+) | C$1/$2 EN 1992-1-1:2004/A1:2014 |
| Material name | C20/25 | C20/25 EN 1992-1-1:2004/A1:2014 |
| Material name | C30/37 | C30/37 EN 1992-1-1:2004/A1:2014 |
This article shows and explains possible problems when defining regular expressions.
The cross-section name 400*400 is not converted with the expression (\d+)*(\d+).
The asterisk * has a special meaning in regular expressions, and is therefore not interpreted as a simple character. To use the asterisk as a single character in a regular expression, you can write it with a backslash \ to invalidate its special meaning.
| Conversion from Tekla to RFEM 6 | Tekla | RFEM 6 |
| Regular Expression | (\d+)\*(\d+) | R_M1 $2/$1 |
| Cross-Section Name | 400*400 | R_M1 400/400 |
| Cross-Section Name | 150*200 | R_M1 150/200 |
The cross-section name RHS200*100*5 is not converted with the expression RHS(\d+)\*(\d+)\*(\d+).
If several similar regular expressions are used, this may result in the use of an incorrect regular expression (see the example in the image).
You can use the superscript ^ to specify using a regular expression only if it is valid at the beginning of the material or cross-section name. The expression ^(\d+)\*(\d+) is thus no longer valid for the RHS section, because this section name does not start with a number (such as 400x400).
| Conversion from Tekla to RFEM 6 | Tekla | RFEM 6 |
| Regular Expression | ^(\d+)\*(\d+) | R_M1 $2/$1 |
| Cross-Section Name | 400*400 | R_M1 400/400 |
| Cross-Section Name | 300*300 | R_M1 300/4´300 |
| Regular Expression | RHS(\d+)\*(\d+)\*(\d+) | RRO $1x$2x$3 EN 10219-2 ALUKÖNIGSTAHL |
| Cross-Section Name | RHS200*100*5 | RRO 200x100x5 EN 10219-2 ALUKÖNIGSTAHL |
| Cross-Section Name | RHS180*140*8 | RRO 180x140x8 EN 10219-2 ALUKÖNIGSTAHL |
How can I convert the material/cross-section from RFEM 6 regardless of the standard designation?
In contrast to RFEM 6, Revit and Tekla assign material and cross-section names regardless of the standards. Therefore, to convert, for example, an HEA 300 cross-section in RFEM 6 into an HEA 300 with no standard reference in Revit or Tekla, you can use the regular expression .*$ to ignore the standard designation in the name.
| Conversion from RFEM 6 to Tekla | RFEM 6 | Tekla |
| Regular Expression | HEA (\d+).*$ | HEA$1 |
| Cross-Section Name | HEA 300 DIN 1025-3:1994-03 Ferona | HEA300 |
| Cross-Section Name | HEA 300 Euronorm 53-62; ... SZS | HEA300 |
| Cross-Section Name | HEA 300 GB/T 11263-2017 -- | HEA300 |
