Inverted Workplane

Hi there, I am working on a project now using Rhino 7. I have modeled the geometry and fenestration. But, when I tried to define the ‘Add Occupied Floor Area’, somehow the defined workplane is positioned outside the room and inverted. So, I tried to make a simple model to check it. However, the similar problem still occurred. Is there any suggestion to solve this problem? Here I have attached the screenshot of my project. Thank you.

Hi -

That is not something that is in native Rhino. Please post this question in the relevant plug-in category.
