I found a fix that worked for me on the sims 3 forums.
Sims 3 see through floor.
Building multi floor homes in the sims 3 is not that difficult in fact it can be really simple.
See links below i think this might have appeared when i deleted a room in the basement but i m not sure.
I can see where you were going with that.
One of my sims keep falling through the floor from the second story to the first.
Use the reset sim chest see if that ll fix your sim.
Label them and lower them out.
By default the sims 2 allow you to built up to 5 levels.
My sims just moved into a house with two floors.
O o a little bit later toby and blacky did the same thing.
You can eliminate the basement or built an underground floor inside basement.
New glitch image.
Ctrl shift c hold all 3 together in the menu bar that appears at the top of the screen type resetsim first name last of your sim.
I had tried a kitchen table to see if that fixed it as opposed to using the dining room table.
The sims 2 is the only game in sims series where you can increase max floors limit using a cheat.
I do not know how to switch my view from the second floor to the first floor and vice versa.
Draw out lines of your furniture label them and lower them out.
Didn t notice it until i toggled back up to the ground level.
I ve deleted all the floors and put it back on but it still keeps happening.
But wait til you see what happens.
The ground and a bit of the floor has become see through in one place showing the basement outer wall and blue nothingness around it.
Right here you can see one of our sims 3 house floor plans gallery there are many picture that you can found remember to see them too.
