Konstru Lines are SAP2000 Frames with "None" Section applied.
Konstru groups are SAP2000 groups.
Groups have no GUID in SAP2000 so Konstru uses names as unique ids. If a group is renamed Konstru shows one deleted group and one new group for the next upload instead of a modified group.
Custom sections in regular shapes (I,C,W,Rectangular etc) are supported. Irregular shapes are currently not supported.
Structural Profiles (Wall or Floor layers)
Structural Profiles are automatically created on download from Konstru.
