How do I merge two models?
Extended Question: I have a substructure modeled in one file, and the superstructure in another. How do I merge the two such that they create a single model?
ANSWER: Models may be incorporated into a single file by opening the destination file, then import the .s2k text files through File > Import > SAp2000 .s2k Text File. Select the Add to Existing Model option to superimpose data onto the open model.

How do I import joint coordinates which are in CVS or TXT
...
format?
Expanded Question: I would like to import, into SAP2000, a .csv or .txt points file into SAP - one of the points represents the start point of a member, which contains comma-delimited joint coordinates. One point represents the member start node, then the next represents the end point. What is the best way to do this? I cannot find an import command that allows the importing of a plain comma delimited text file. The file is generated from another program and node. The file was generated using another software, and now I would like to use SAP2000 to analyze the structure with SAP.Answer. What is the best way to do this?
ANSWER: The best approach to import the joints coordinates would be to use Interactive database editingDatabase Editing in combination with an Excel spreadsheet. The steps involved are outlined belowas follows:
- Create a new model.
- Go to "Use the Edit > Interactive Database Editing " and check "menu to select Expose All Input Tables" , located on the right side of the form.Now select table "Joint Coordinates" located in "MODEL DEFINITION .
- Select Model Definition > Connectivity Data > Joint Coordinates > Table: Joint Coordinates "Click OK, this will open "to open the joint coordinates table.
- Select OK to open the Interactive Database Editing - Joint Coordinates " form. Click "menu, then select To Excel" button , located on the right side of the form.
- Cut and paste the content of the CVS or TXT file into Excel and place , then organize the data into their corresponding columns.
- Return back to the " Interactive Database Editing - Joint Coordinates " form and click "menu and select the From Excel " buttonoption. This will transfer the data from the Excel spreadsheet to the into SAP2000 form.
- Click "Update the SAP2000 model by selecting Apply to Model " and "Done" buttons to update the SAP2000 model> Done.
Can I open my file in a

previous version of the

software?
While the input files are not backwards compatible due to the changes that may be introduced to the database tables in higher versions of the program, you may be able to use the following manipulation to import your model to a lower version of the program:
...
ANSWER: Software changes made to the function of database tables prevent input files from being backwards-compatible. However, users may be able to import a model to a previous software version through the following process:
- Export the file in S2K text file format.
- In the Program Control table (search for string "Program Control"), modify the file version (ex. 12.0.2 to 12.0.0, in the Program Control table.).
Figure 1: Replacing the program version in the model text file
- Open the lower version of the program software and import the text file previously created in the previous step.
This approach should generally work if the two versions are "close enough" to each other, unless there was a change of database schema that directly affects the data stored in the file.

- .
Unless a database change was made between software versions which directly affects the storage of file data, this procedure should be effective so long as the software versions are relatively close in sequence.
Users should check the import log for any error or warning and error messages. I would also recommend to messages, and carefully review the model once data is imported, to the lower ensure successful transfer to the previous software version.

You can ANSWER: To validate an IFC file, users may first try to first open the IFC file in using one of the IFC viewers listed at on the iai-tech.org website. We had a good experience with CSI recommends using the free CAD-DDS viewer.
How can I ensure that a CIS/2 file is valid prior to import to CSI software?
ANSWER: Users may upload a CIS/2 file to the online version of the NIST SteelVis tool to generate a VRML file in one of the following formats:
A text file in which the VRML text file can be downloaded to a local computer and viewed by such VRML viewers as FreeWRL.
- A 3D interactive VRML model, which requires installation of the VRML plugin to the browser.
