I. To import a CIS/2 file
To import a CIS/2 STEP file, use the following procedure.
The initial structural model will be created in your external 3D modeling software and
exported as a CIS/2 STEP file, consisting of both analytical and physical model
definitions. Limited load modeling can be done in some modeling software –such as SmartPlant® 3D– before the
initial export.
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. STAAD.Pro can import data from those types known as analysis models.
Note: If you
are importing into an empty STAAD input file, then you will be creating a new file.
Otherwise, the program assumes you are updating an existing file with changes in a CIS/2
file.
The following data can be imported through the
CIS/2 format:
- Member properties (see I. Supported Shapes for CIS/2 Import for a list of supported section shapes)
- 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
- Select the File ribbon tab. The backstage view opens.
-
Select the Import/Export tab and then
CIS/2 in the Import group.
A Windows Open dialog opens. - Select the CIS/2 (*.stp) file you want to import and then click Open. The Cis2Link dialog opens.
- Either: The data is read and the import progress is reported in the log window.
- (Optional) Click Save Log File to save this information to a text file.
- Click Close.
