Computers and Structures, Inc. is pleased to announce the release of CSiXRevit, a link that allows for data exchange between ETABS® v9.7.3/SAP2000 v15.1.0/1 and Autodesk Revit® Structure 2013. CSiXRevit supports true round-tripping, specifically - four different workflows of data interchange:
Exporting from Revit Structure to create a new ETABS/SAP2000 model
Exporting from Revit Structure to update an existing ETABS model
Importing from ETABS/SAP2000 to create a new Revit Structure model
Importing from ETABS to update an existing Revit Structure model.
The CSiXRevit link is a powerful integration tool, allowing you to maximize the capabilities of ETABS/SAP2000 and Revit® Structure 2013.
CSiXRevit supports both 32-bit and 64-bit versions of Revit® Structure 2013.
CSiXRevit for Revit® Structure 2013 is only compatible with ETABS v9.7.4 and SAP2000 V15.1.0/1.

This International Standard specifies general principles of risk assessment for systems involving structures. The focus is on strategic and operational decision-making related to design, assessment, maintenance and decommissioning of structures. This also includes formulation and calibration of related codes and standards. Systems involving structures can expose stakeholders at various levels in society to significant risks. The aim of this International Standard is to facilitate and enhance decision-making with regard to monitoring, reducing and managing risks in an efficient, cost-effective and transparent manner. Within the broader context of risk management, risk assessment provides decision-makers with procedures to determine whether or not and in what manner it is appropriate to treat risks.
This International Standard provides a general framework as well as a procedure for identifying hazards and estimating, evaluating and treating risks of structures and systems involving structures. This International Standard also provides a basis for code writers as well as designers to set reasonable target-reliability levels, such as stated in ISO 2394, based on the result of risk considerations. For existing structures, assessment of the risks associated with the events that were not considered in the original design or with changes in use shall be implemented according to the principles stated in this International Standard. This International Standard can also be used for risk assessment of exceptional structures, the design of which is usually beyond the scope of existing codes.

This International Standard specifies general principles and recommends procedures for the verification of the durability of structures subject to known or foreseeable environmental actions, including mechanical actions, causing material degradation leading to failure of performance. It is necessary to ensure reliability of performance throughout the design service life of the structure.
Fatigue failure due to cyclic stress is not within the scope of this International Standard.

Print2CAD 2012 is able to convert PDF files into a DWG or DXF file, which can then be imported into any CAD system for editing. Print2CAD 2012 is an autonomous and CAD system-independent program. Print2CAD 2012 also converts DWG/DXF into PDF, TIFF/JPEG into DWG, DWF into DWG/DXF and HPGL into DWG/DXF.
Print2CAD 2012 not only uses conversion and vectorization methods, but also uses OCR (Optical Character Recognition) to reconstruct the content of a PDF or raster file. The program can also recognize the PDF text that has been deconstructed into polyline fields, and/or pixel pictures as full and editable CAD text.
