The model can be changed by invoking the UI command "/mydet/SelectDetector ", where is the name of the STEP file .stp which describes the detector geometry. Due to limitations of the NIST STEP reader, a correct behavior can be assured only for non-ISO/ANSI setup of compilers (i.e. egcs-1.1.2 or old non-ANSI compilers) as specified in the notes for the SCL-3.2 package. Therefore, the GNUmakefile in this example has been modified to force non-ISO/ANSI compilation on Linux platforms, to allow the code to build. AP203 STEP files showing errors in the reading process, can be formatted using the PERL scripts provided in the "scripts" directory; most patterns will be corrected. If errors are still observed, please inform us so that the scripts can be enhanced.
