There are several stanard profiles missing from the libary
Those i have found:
TREC: all 100x60xXXmm, 180x100xXX mm, 200x120xXXmm, 450x200xXXmm, 500x300x20mm profiles.
In general there are missing more profiles with different thickness. I am more interested in getting more profiles, and the engineer then crosschecks the local steel factory for their standards.
Hope this is looked into.
