patio built with the railing tool changes footings

[Reiter]

I'm having trouble figuring out why and how the patio I am creating with the railing tool is changing the footings. It would be a little more understanding if it were just on the adjacent walls the patio connects to, but it is even having an effect on walls across the room. The attached video will show you what I'm experiencing.

When you connect the railing wall, the program will make a room.  Depending on your room settings it can also change your foundation.  I am guessing that you have auto rebuild foundations on, otherwise you probably wouldn't see it change like it does in the video.

 

I am also going to guess that there is something going on with the porch room that is messing up the rest of the foundation.  Might want to take a look at the room structure settings and make sure your porch is really setup the way you want it.  

 

Another thing you can try is just closing and then reopening the plan.  Chief seems to keep track of old room info which can sometimes mess up new rooms but if you close and reopen the plan it seems to get rid of it.

 

If none of that helps, then you should probably post the plan.
