Staad.pro Connect Edition update 3 + openstaad API + .NET C#

Hi Chinna

With the latest version of STAAD.Pro, the distribution of OpenStaadUI.tlb file has been discontinued. Instead, we have embedded the file inside ‘StaadPro.dll’. You need to add the ‘StaadPro.dll’ as a reference to lookup the methods in Intellisense box. However, to run the code, TLB is not required.

I hope this helps,

Hello All,

Adding StaadPro.dll will not help in C# application. You need to add the interop dll. Please create the dll by following steps:

1. Open up command prompt.
2. Go to C: or D: or any folder other than ‘Program files’ or system folders
3. Now, type "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\x64\TlbImp.exe" " C:\Program Files\Bentley\Engineering\STAAD.Pro CONNECT Edition\STAAD\StaadPro.dll" /out:Interop.StaadPro.dll

The output DLL will be found in the folder where your command prompt is pointing.

Now, add this dll to your C# project and you can access the OpenStaad application object.

Let us know if this has helped.

Regards

Hi Vivek, Chinna,

I am attaching a sample project which will demo how to connect to a running STAAD instance and query data.

Please note the following:

1. Launch an instance of STAAD and open a model file

2. Launch Visual Studio 2017 and open the attached Sample project. (Note: configuration should be a x64 one)

3. Build the project and run it.

4. It will print the node numbers in the opened model. The sample project uses the geometry interface. Likewise you can use others.

SampleOSApp.zip

Note: If you want to access specific instance of STAAD, please refer /cfs-file/__key/communityserver-discussions-components-files/5932/Using-OpenSTAAD-application-object.pdf. This refers to an old version of deployment but the code snippets provided is still valid.

Hope this helps all.
