Closed EAzari closed 3 years ago

EAzari commented 3 years ago

It would be better if further IFC X specs include the "Optional" column in Attribute tables (Attribute definitions and Attribute inheritance)

Currently, tables have these columns:

Optional is denoted by ? in the Cardinality column.

EAzari commented 3 years ago

@pjanck thanks Stefan, yes, however, I think Cardinality is related to sets and grouping, and it'd better have a separate column for Optional If you think it doesn't cause misunderstanding, we can continue that way

pjanck commented 3 years ago

I understand your point. If you think a separate column would increase the readability of the documentation, you're welcome to contribute here. I'm not sure which file needs to be adapted, but I'm sure you can figure it out :)

This is not a NextGen issue.
