During numbering, the compound profiles in Advance Steel behave in 2 ways:
The default is that the compound profiles behave as one profile. This behavior is available in lists, drawings and numbering.
The behavior as one profile involves receiving a single part mark number (1002) and an assembly number (2). The single part number will appear in lists and drawings as the number of the compound profile. Also the representation type of the compound profile must be "Complete".
Advance Steel allows the user to choose the behavior of a compound profile such as split profiles.
The behavior as split profiles involves that the numbering proceeds as follows: each one of the profiles that define the compound section will receive a single part number and the same number for the assembly mark. For example, the assembly number is 1 and the single part numbers are 1000 and 1001. Also the representation type of the compound profile must be "Separated".
This behavior is available in lists, drawings and numbering. During numbering, this compound profile as a whole will receive a single part number and an assembly number. These numbers will have negative sign, for example, -10004 for assembly and -10001 for single part. To see these negative numbers, the representation type must be "Complete".
Advance Steel numbers the compound section to identify it, but the negative sign disallows the display of this profile as a compound section in drawings and lists.
