Best Workflow for compressing large, vector-based PDFs in Indesign?

Hello,

 

I have a 20 page architectural portfolio in Indesign, consisting of renders as JPEGS, and several complex CAD files as PDFs, and text. I am trying to export as PDF to a file size under 10MB without having to rasterize the drawings (I want the drawings to read as vectors). Any advice as to how I can achieve this?

Well the variable here is "several complex CAD files as PDFs". It will likely come down to getting the CAD > PDF file sizes down prior to placement in InDesign. How many is "several"? How "complex," and how were the PDF's generated?

5 drawings, generated as DWG's in Rhino, and cleaned up for presentation inIllustartor. I exported from illustartor as PDF and placed them into Indesign.

You probably won't be able to control much with the initial PDF export out of InDesign, but once the PDF had been generated, you can use Acrobat to try to reduce the size of the PDF. Try using File > Save As > Optimized PDF in Acrobat and adjust the settings to see if you can get the file size small enough. I also find it helpful if you open up the Content pane in Acrobat and click on the Option button at the top and choose Audit Space Usage. This can sometimes give you insight into what is utilizing the most size of the file.

If you export as "Interactive PDF" all vectors are already zipped.

Neither Acrobat Pro nor any other software will be able to compress them more because we do not know how to degrade the quality of vector objects by compressing them.

 

If you export as "Print PDF" be sure to check the "Compress text and vectors/artworks" option (I don't know the English item since I use a localized version).

Why do you want to do this? I'm not trying to be a jerk, but it's entirely possible you are not being reasonable.

20 pages with any graphic content is going to be take up some storage space. If you can tell us the end game here we can offer much better advice.

The goal is to be able to send it directly to firms in an email. I might just need to resort to sending a link out instead because I've tried everything.

Also, how am I "not being reasonable?" The entire reason I posted to this forum was to get advice... and I am sure there's a way to do it, as Indesign is an extremely powerful tool.

Not you personally...the goal of getting this down to under 10MB.

 

There's a limit to how much you can compress these things without destroying the quality. By all means provide a link; you're far less likely to wind up in a spam folder, too.
