Examples:
Influence front plate thickness and material:
Front plate feature: Parameter ID: item_id_sv ('SHEET';'MATERIAL';'S235JRG2';'S';20)
Girder height of an I-beam:
I-beam feature: Parameter ID: item_id_v('DIN_1025-1';'H';200)
Explanation
How do I access the standard description?
Let us assume that the thickness of a front plate needs to be parameterised. The thickness itself is not made available in the feature, as it results from a row of a standard file. If you expand the generation feature of the front plate, you will see 'Catalogue: 127'. 127 is the internal representation of the standard file for sheets. To infer the name of the standard file from the number, you open file \Kataloge\sys\TBLIDs.DAT. Here, you look for the row with value 127 and thereby obtain the precise description of the standard file: 'SHEET'.
How do I access the column names?
You now find file 'BLECH.ipt' in the \Catalogues directory, using a text editor to open it. You will find the columns with their precise descriptions and data types in plain text here.
