Welds
Welds are created as weld points or weld lines. These objects contain not only the weld properties but also the logical connection between connected structural parts.
Connections
Advance Steel objects are added or deleted from the bolt or weld connection objects with specific tools. At the same time, the grip length (and bolt length) is modified.
Special parts
Special parts are parts used in the Advance model and in the structured BOM or drawings that cannot be created from other Advance objects (e.g. turnbuckles).
