Is that you can save directly from the Mac Preview, it's like the windows right-click on the plot preview window but just using Mac preview!
It's because if you're coming from PC to MAC you've probably not used a Mac before... Once you figure out the MAC way to do it, then you realize that it's even cooler because, usually a MAC has cooler ways of doing things!
I just saved an entire set of plans using the MAC pdf preview!
The only thing I don't like about the Preview app is that it doesn't retain vector objects (which make file sizes smaller). I suspect this has something to do with the way OS X renders the files. Would be great to have vector PDFs!
I can't agree with your words:
In fact all objects in PDF output from AutoCAD for Mac, except for raster images attached to DWG, are vectors.
Another thing - how the these vector objects. are formed. Here we must say that the PFD engine in AutoCAD for Mac is still far from perfect.
BTW, when DWG to PDF output appeared for the first time in the Windows version it also was not brilliant.
I'm not sure if there are any setting you can change, but all PDF's that I create are definately a "flat" PDF image. No vector information (lines/layers etc) is retained.
There are no settings for PDF output in AC for Mac.
Yes, you are right - AC for Mac doesn't maintain Layers in PDF output and it converts all text to vector objects (like Adobe Illustrator function "Create outlines"), and the last is one of the reasons for growing PDF file size.
But if you open any PDF file, created in AC for Mac in Illustrator, or if you don't have it - in Inkscape, you will not find raster data in it (as I say except for referenced Raster images, if any) - there are only vectors, you can check by yourself.
