Main floor wall not aligning with foundation walls

[Manpreet13]

Hello,

 

I am fairly new but have spent some months to design my own home. I have come across a problem where I am trying to align my first floor walls to the foundation walls however, the first floor walls goes offset inwards if I use auto align tool. I am also noticing a notch along the top outside of my foundation wall. These 2 issues seems to be at same location of the house plans. Any help is appreciated.

Your wall definition probably has a very thick siding layer.  The program is trying to provide a brick ledge and make the alignment work with that siding thickness.
