Need help >> I can't plot this drawing. (attached)
RECOVER opened the file without complaint or errors found.
I tried to plot the file in AutoCAD Architecture 2016 from the Model tab, using the AutoCAD PDF (High Quality Print).pc3 printer. I do not have your BWH Std - full scale line wts.ctb file, so I got a warning message in the Plot and Publish Details dialog, and it plotted with the object colors. When trying to open the resulting file, however, Adobe Acrobat Reader DC gave an error stating that the "file is damaged and could not be repaired." I had tried to move the PDF file while AutoCAD was open, and got a message saying it could not be moved because AutoCAD still had it open. I also had a warning about the plot scale of 1" = 50 units not matching the annotation scale (1:1), but I told it to continue.
I tried plotting the file with the mononchrome.ctb plot style, to take the missing plot style out of the equation. The Plot and Publish Details thinks everything went just fine. Acrobat Reader tried to open the file, but did not succeed, complaining that the file is already open or in use by another application. After closing AutoCAD and giving it a chance to fully shut down, trying to open the PDF results in the same error message about the file being damaged.
I tried again with the annotation scale set to 1:50 with no difference.
Any idea what changes may have been made to the file between the time it worked and it did not work? You said copying the contents to a new file did not work, so the only other thing I can think of is to create a copy and delete everything on one half of the drawing. Try to plot. If that works, then the bad element/elements must have been in the deleted items. If not, then presumably the bad element is on screen. Continue with that until you can narrow it down to one or a few elements causing the problem, and then replace them with "good" equivalents. That assumes that there is one or more visible elements in the file that are causing the problem, which may or may not be the case.
One question, that most likely has nothing to do with the plotting problem: Is there a reason why you are plotting what appears to be an imperial drawing at a metric scale (1:50)? 1:48 (which is more commonly denoted 1/4" = 1'-0") would be the closest standard imperial architectural scale.
I tried today, on my work machine, and had no problem creating a valid PDF with the AutoCAD PDF (High Quality Print).pc3 printer.
One thing that occurs to me now is that my home computer is new as of a few weeks ago, and I most likely have not installed all of the updates on AutoCAD Architecture 2016, whereas I believe I have them at work. If you type ABOUT and press the ENTER key, what do you see for the Product Version and Built on? Does it look like this (which has SP1 for both AutoCAD and AutoCAD architecture installed)?
