Try changing the family Visibility Graphics. You may have to check the box for Course, Medium or Fine.
Gents,
As I found the solution - Please change the View Depth in the View Range, Change it to your required ''Level below or Unlimited''
I hope this will work.

This is the solution thank you! I Changed my plan view from architectural to structural foundation plan and it automatically switched to looking down and my foundation walls ver visable
If your Floor Plan can work using a Structural Discipline---
View Properties>Structural Discipline>Show Hidden Lines by Discipline
If you need the footings to show dashed on an Architectural Plan View--Set up a Level called Foundation. Then,
try using an Underlay set to Level: Foundation. You will see the footings below. Then use the Linework Tool
and select the outlines of the footings and use a Hidden Line Style. Then turn off the Underlay. The Linework will remain visible, and it will adapt to any future changes in the footings.
It may be a stupid question, but have you checked that you are in "Floor Plans", and not in "Ceiling Plans"?
