List of standard profiles is limited in Classic

Whenever I use standard profiles I only have a choice of about 3 or4 sizes for rectangular or square or circular. This is obviouslynot the complete set of ISO standard sections (from memory forexample, I think the RHS is 50x50, 60x40 and another).

Is this another limitation of Classic only? Do office Pro orpremium users get the full ISO set?

How can I add more standard sections to the list?SolidworksWeldments
