Not the first time this will of been discussed. We are desperate for a solution or workaround to the problem of PDF file size/complexity.
We have a large project with 200+ drawings and a client that cannot open the majority of the files unless we open the ArchiCAD published PDf files in photoshop, flatten them, and then re-save as a PDF.
I have tried various combinations in the publish options within ArchiCAD and there is no option to genuinely 'flatten' what you see. We're not interested in preserving layers etc (that's what we have DWG's for).
Does anyone have a low-effort workflow for reducing files like this en masse?
I am considering that if I can add an 'acrobat' print driver to windows, then I could possibly select 'print' from the ArchiCAD publisher (instead of publish) and then tick 'print as image' but this is a long shot.
I have looked at the PDF files you uploaded for me. A few thing that come to mind:
- Some of these Fill patterns are pretty dense, which means they take quite some time to draw in Acrobat. You could try to make them less dense, if it is feasible.
- Fill pattern Pens have a thickness. I am wondering if it would make any difference if Fill Pattern Pens were hairline Pens. You could test this by creating a new Pen Set based on the current Pen Set used, but in this new Pen Set you would set the thickness of all Pens used for Fill patterns to zero. This could potentially make the PDF lighter and faster to redraw. (Of course the other option is to use the Hairline option in the PDF Option Dialog, but you may want line thicknesses in other elements.)
But the main issue seems to be the "non-flattened" way of saving these PDFs. When I open the PDF and Pan around in it, I can see that a lot of drawing content is drawn, only to be then covered with a large Fill. These elements shouldn't be saved with the PDF file to begin with. And if I understand correctly, this behaves the same even if Layers are not saved to the PDF.
I would recommend that you create a wish for a "Flatten View content before saving as PDF" option in the PDF Options Dialog. That would be a very useful and intelligent option for ARCHICAD and I am sure users would support the wish. We could then vote for it and submit it to GRAPHISOFT as a wish.

Agree, one of the fills is very detailed. This is quite deliberate, however - we often draw tiling to actual size including grout joints to make sure when we are space planning the tiling setting out is being considered at all stages.
Will give your recommendation a try on line weights and in the meantime have created a poll for the issue;
I would be interested to learn if anyone has a workaround for this outside of ArchiCAD? We have tried batch processing the PDF's in photoshop but for whatever reason, we have only ever managed to do this with one drawing at a time (not a practical way to continue).
I am having a similar problem with publishing to PDFs -- the file is so large that watching it regenerate in Adobe Acrobat is like watching an etch-a-sketch screen, and the file crashed the plotter at the print shop that I usually use a couple of times before we were finally able to get a hardcopy.
I am still in early stages with my CD set, so by the time the set is ready to be released, I am afraid it will be so large as to be useless.
I've reduced the PDF file size somewhat by removing hatch patterns from the roof plans and substituting air space for insulation in my composite walls, but that's not a great long-term solution.
Ought to add that I am new to ArchiCAD, so I may be doing something really bone-headed. Would appreciate any further suggestions from more experienced users...meanwhile off to see if I can figure out how to flatten the PDFs.
