Floor Joist on Garage Slab

[ChiefBen2024]

Hello, I was able to figure out to convert one slab and partition into garage and then had the garage lower than the attached home. Although, I don't know what the grey lines are  that was created on each side (top and bottom).  I am doing a garage conversion and need to add 6 inch joist in the garage. I figure 16 inch on center between joist. How do I get it to build automatically on the garage slab.

 

thanks,

Ben

Thanks I was able to manually put in the rim and floor joist. I also simplify it by making the other half of the slab the same as the attached home. The only thing that isn’t showing is the slab underneath the joist. Perhaps I can build a slab underneath it.
