Pencil Tool path not covering all desired areas

[kentdesautel]

I am not able to get the pencil tool path to cover all areas on this work piece. Currently it's going down the corner path on the back wall ( which is what I want ), but I would also like it to follow the bottom curved edge face ( Highlighted in Yellow )

Here is a link to the file:

Thank You,

Add a touch of overthickness:

 

Use avoidance surface groups if you don't want to process the upper edges.
