What are the common file formats that can be imported in STAAD?
STAAD.Pro can import data from the following file types:
The import-export options are mentioned in the following picture --
CAD models such as those from AutoCAD or Microstation can usually be saved or converted into DXF or CIS/2 files.
From the 3D DXF format, only the line diagram (geometry) of the model can be imported. Property or load data cannot be imported from such files.
The CIS/2 (CimSteel Integration Standard, Version 2) allows for the transfer of models using a prescribed data standard in the STEP (Part 21) format. There are various types of CIS/2 files. Among those, STAAD can import data from those types known as analysis models. The initial structural model will be created in the external 3D modeling software and exported as a CIS/2 STEP file, consisting of both analytical and physical model definitions.
The following data can be imported through the CIS/2 format:
• Member properties
• Material constants (E, Density, Poisson, etc.) of steel profile sections
• Member orientation (Beta angles, Reference points)
• Member end conditions like Releases
• Support conditions
• Loading information
STAAD.pro is also an ISM Enabled application allowing data to be imported, exported and updated (or Synchronized) with other ISM enabled applications.
