I got your file and have been looking at it. You have spent a lot of time on this drawing, a lot more than needed. Most of the white spots are lines, arcs, and polygons that need to be deleted or hidden. I don't recommend using smart polygons as construction geometry, it doesn't create associative links with the extruded part. Use the single line option. For multiple instances of a part hold down the option key and drag out a copy, much more efficient. Pause every once in a while and delete stuff that is no longer needed. Construction geometry that I want to keep I move to the construction layer and hide the layer to keep it out of the way.
In one of the screenshots there is a reference to several polygons on top of each other, this is very easy to do and not know about it. There are several instances of this happening in the drawing, another good reason for dragging out copies.
There is an overuse of grouping here. When I tried to hide the arcs in shot 2 I couldn't do that until I ungrouped the top group only to find they were part of a second level group which I had to ungroup in order to use the Select Deep tool to select the arc that was yet in another group.
