1. How can I get my RISA model into STAAD.Pro ?

There is no way to directly get a RISA model into STAAD.Pro. You may check whether RISA can export in the following formats, both of which can be imported by STAAD.Pro.

1.  CIS/2
2.  3D DXF

Out of these, the CIS/2 is the best option as it lets you transfer not only the wireframe but other member information like Member properties, Material properties, Member orientation, Member end conditions like Releases, Support conditions, Loading information

3D DXF transfer will let you transfer the wireframe only.

These import options in STAAD.Pro can be accessed from within the top menu File > Import

P.S. Although this wiki is about RISA, but it applies to other analysis software as well.

2. I do not see the option import/export using StrucLink under User Tools section.

There could be few reasons behind this.

1) You must not have installed the StrucLink while installing STAAD.Pro.

2) You may have installed StrucLink sperately, but there is a version mismatch.

To fix it, uninstall STAAD.Pro & any version of StrucLink you may have from Control Panel (Add/Remove Program or Programs and Feathures)

Reinstall STAAD.Pro, for Windows Vista/7/8 operating system, right-click on the .msi./.exe file and select the option "Run as administrator" (though you are logged in as administrator). If you run the file as the local administrator only, the program will not be installed properly. "Run as administrator" option is a must; you may need help from your IT personnel. Ensure that the check box next to the "Install companion product" is checked.

Once installation is done successfully, you should see the following options under "User Tools" section.

3. How to Open a QSE File?

Go to File > Import… and select QSE ASA option:

4. How can I get data transferred between STAAD.Pro and Autopipe ?

The transfer of data between Autopipe and STAAD is done through Pipelink. You should ensure that you have the latest available versions of both STAAD.Pro and Autopipe software. The data transfer process is explained in detail in the document PIPELINK_tutorial.pdf

5. How to import a section from the Section Wizard into STAAD.Pro?

1. Create your built-up section in Section Wizard.
2. Go to File -> Export to STAAD User Table.
3. Choose General.  You will see the Open User Table dialog box appear.
4. Either Select an existing UPT file or create a new one and click Open.
5. Choose the desired units.
6. You will see the General dialog box appear:
   
7. Input a name (shown as TEST2 above).  You will notice that the properties are shown here.
8. Click OK.
9. Close Section Wizard and go back into STAAD.pro.
10. Go to Tools -> Create User Table.
11. Click New Table.
12. Check the box that says External Table.
13. Browse to the UPT table that you created/selected in step # 4 above.
14. Select the Section Type as General
15. Close out of the dialog box to return to the Modeling Mode.
16. Go to the General -> Properties tab.  You will see the Properties dialog box appear on the right hand side of the screen.
17. Click on the User Table button.
18. Select the appropriate user table, click on the section name, and click the Add button.
19. Assign the section to the appropriate members.

6. Why my DXF drawing is not imported correctly from AutoCAD into STAAD.Pro?

There are basically 3 rules to adhere to when generating these DXF files from AutoCAD:

1. All entities must be modeled in your AutoCAD model using simple Lines. STAAD does not import polylines or curves of any forms. You must "explode" the polylines or curves and convert them into simple line entities in AutoCAD before you create the DXF file.
2. Plate elements if any, must be modeled using 3DFace entities in AutoCAD.
3. Since solid element data cannot be stored in DXF files, STAAD cannot import solid element data.
