Tekla Structures is Building Information Modelling (BIM) software that enables the creation and management of accurately detailed, highly constructable 3D structural models regardless of material or structural complexity. Tekla models can be used to cover the entire building process from conceptual design to fabrication, erection and construction management. nteroperability Tekla Structures can be used to interface with other existing applications, or solely as a platform to develop a customisable internal solution. Its open platform supports interoperability and standardisation. Tekla Structures links with various systems through Tekla Open API™ application programming interface that is implemented using Microsoft® .NET technology. Examples of standard formats supported by Tekla Structures are IFC, CIS/2, SDNF and DSTV. Examples of proprietary formats supported by Tekla Structures are DWG, DXF and DGN.
