Were the parts in that view in a layer that was not translated through?
How did you translate it from Solidworks to AutoCAD? DWG/DXF? If so, check your layer map.
I don't use layers in SolidWorks. I save to .dwg. All the layers in AutoCAD are feature driven. This is my map.

I'm guessing the views were on a different layer as Dan stated.
If not, perhaps during the save-as as a dwg, the file had a rebuilt on those views and grayed them out.
Do a rebuild and save your drawing file before saving as PDF. Other option is to use print as PDF using third party pdf printer tools like cutepdf, foxit, etc.
Saving to PDF works fine, it's saving to .dwg that's the issue.
wow....why the need to save as dwg? Is it possible that the layer may be turned off for that view? Stranger things have happened.
I never used the layer mapping when saving a file to acad...and would get a nice looking model space views. Kill the tblk and them use the paperspace to add all the info back. Kind of double work but when the customer is paying for it and there is work to do why complain.
Out of curiosity, why do you save SolidWorks to AutoCAD?
The Assembly file is huge and sloooow. I want to add a part to one of the sub-sub-sub-assemblies, and I needed to get some geometry data from the top level assembly. I thought it'd be quicker converting the drawing to AutoCAD and taking measurements from the AutoCAD.
I would update the computer and dump ACAD. More efficient.
Would that I could. However, all I can do is complain to IT.
You can use eDrawings OR open the top level assembly in Large Design Mode and take the required measurements.
I have "Large Assembly Mode", which I think is the default for assemblies over a certain size. Did they rename it "Large Design Mode" in 2018?
I don't know how large of a sub-assembly you are working with but if it is not all so large, perhaps you could clean it up by removing unneeded parts/assemblies and defeaturing the ones you need?
I've had to deal with a company that writes their name on EVERY. SINGLE. DAMN. PART. MULTIPLE. TIMES.
When I do get those drawings, it is a real pain. I end up having to shuffle through it for an hour to figure out what I need and don't need. After removing everything I don't need, I look at the parts I need and see if there are details I don't need such as bolt threads, company logos, anything that brings nothing to your drawing.
If the drawing gets too heavy to work with, perhaps you could work with isolate to create the display states you require to add the extra part.
That is part of my problem. The guy who had this project before me didn't use the Toolbox; instead he downloaded fully featured models from McMaster-Carr. So part of what I have been doing is replacing fasteners with toolbox parts, and creating "lightweight" configurations of sub assemblies that have the fasteners suppressed and as many defeatured parts as possible. Still, there are layers upon layers of sub assemblies.
I DO use SW layers, and do not use a conversion map when I export to ACAD (though I may start to use one now that I've seen your map which is very interesting).
That said, the only thing I can add is this and it may not apply when you use a map: When I convert SW drawing to DWG, the first thing I do in AutoCAD is select all, and set all the elements' color to be driven by layer. For some reason, frequently some elements get set to color=black and thus become invisible on the black background of ACAD.
It sure is interesting that the missing bits are on the 2 sections.
