Turn off interior walls in section view

[Jambruins]

Is it possible to turn off interior wall in a section view?  

[MoeGia]

You can make a new layer such as walls, interior.  Move your interior walls you don't want to see in section to that layer.  In your section view layer set, turn that new layer off.  Also, remember to turn that new layer on/off in all of your layer sets so you don't have missing walls where you want them!

To expand, it is important to note that creating a copy of an existing layer will keep all the initial properties of the copied layer.

In other words, to move interior walls to a new layer, do not create a new layer. Rather, make a copy of the layer Walls, Normal and rename it Walls, Interior (or whatever you'd like).
