I created a two story ranch home that has a basement and a first level. I was able to create the foundation and interior fine but I need to put windows in the basement and cannot figure out how. The window will go on the interior walls but will stop at the foundation wall. I can create an egress on the outside with a hole through terrain build but the window will not go through the foundation wall. I'm guessing I did something wrong in the creation...but I am completely clueless. Any help would be appreciated, thanks!
