Exporting to PDF makes line weights appear thicker

Hi,

I'm an architectural student, currently working on my portfolio. In this portfolio there are many drawings with specific line weights.

When I export to PDF directly from AutoCAD and view the drawings in Adobe Acrobat, the line weights are properly displayed.

HOWEVER, Here's my problem;
If I place the  AutoCAD-PDFs in an InDesign document and export them again with absolute maximum PDF quality, the line weights are then displayed incorrectly in Acrobat (they all get alot thicker and a bit messy). The line weight information is not lost though, which can be seen by printing the PDF on paper or zooming in while in Acrobat. This means that the PDF files made by Indesign have a different script for how they are to be viewed on screen.

Now I know that some of you might say that I need to use the setting "Fix Hairlines" in Adobe Acrobat. Even though that works, I don't want to rely on the assumption that people viewing my work know that they can adjust their own Acrobat settings.

I also don't want to rasterize my drawings as high resolution images, I would like them to be real vector lines.

My point;

I want the PDF-file created with InDesign to take care of the view settings itself, as the AutoCAD-PDFs do.

Does anyone know how? Thanks.
