Hello,

Is there any place where I can download previous versions of the stko like version 3.3? If you could give me any link I greatly appreciate it...

Thanks,

Here's a link to the 3.3.0 version:

However, we do not recommend using older versions as they might have some incompatibility with the current version of OpenSees.
