problem with cut view of solid with hole in the center

Question

I was making a more complex model (hollow core slabs) where I noticed the problem. So I tried it in a new model with basic solids, to see if that problem also appeared. Here is the setup: 
 I have a simple slab solid. I attached a part to it. I also have 2 slab solids, one at the edge and one in the middle of the big one. You can see the setup with a clipping applied to it (image 1). 
 When subtracting the solid at the edge, it seems perfect (image 2), but when subtracting the one in the middle the solid doesn't seem solid anymore (image 3).

I also noticed when using the clip volume in other directions (plan view or parallel to side view) the section is ok, when using the parallel to front view clipping (which is the direction you see above) the problem accurs. It looks like the front view settings are ok, just the cut view settings don't seem to work?

I would suggest simply placing 2D shapes where needed and using the Cut Solids By Curves tool with Cut Mode set to Through instead. It's essentially the same end result but it may be easier to place shapes knowing the intent. 
 
As far as what you're showing in that last image... yeah, it doesn't look "right" by any means. Please try the above and see if that helps.

OK 
 I opened your file and did move the items so I could easily cut one section. 
 Now this may be a workflow thing as I KNOW that the WORKFLOW is not apparent "unless you already know how to do it". 
 I select the Drawing Composition tool for SECTION 
 I select a seed that is for a Building or Detail Section 
 I select the section cut as you see it 
 I don't like the automation process - so I don't let it create a sheet or Drawing Model 
 I name the "Saved View" that is created 
 And then I will open the Utility - Saved Views and apply that view to a Window in this file to see if it is like I want it 
 It WORKS for me

This did not show it well so I've added this next screen shot. Note that view 5, 2 and view 4 are actually cuts. 
 I changed the mode to illustrator in view 5 to make it more apparent. 
 Notice your smaller piece is very thin.

Don't use the clip volume tool as you have the section or plan tools. These have all the settings available for you. 
 OK here is with concrete, masonry and brick - from my part library 
 The work fine in elevation 
 The Solid can hide the pattern as the colors may be the same 
 The angle can distort the pattern as seen but it does plot right and if you hover over that edge it looks correct. 
 Not that my materials here use the geometry mapping to pattern the sides for Brick and Masonry. Concrete No.

IT IS A BUG. 
 Once I changed the part to have a solid fill when cutting a section -

I was able to reproduce the issue in the sample file provided. I also created a new file with a similar shape and so far I can see the same effect on both files. In any case it seems like a "Defect" I will let you know.
