I often work with 3D CAD models, which I receive as SolidWorks or PDF files. I need to turn them into black & white line art, like you'd find in a patent application. (In fact, exactly like what you find in a patent application!)
Acrobat-9 allows me to rotate & scale the models, so I can print them with reasonable resolution, but the rest of my drawing toolchain deals with SVG files, while all I can get out of Acrobat is bitmaps. (I also make models from scratch in Blender, and make line drawings using rendering procedures there, but that also produces bitmaps.)
Is there some way to get from a 3D view to an SVG picture (preferably with relatively simple Bezier curves and scaled line weights)?
(As an example, imagine that I have a 3D model of a cube. I position it as desired, then (somehow) convert it to an SVG image with several straight lines where the edges are, with the line weights scaled according to the distance between the edge and the camera/viewer.)
if you have rendered views as PDF files, you can use inkscape's command-line tool to convert PDF to SVG, as discussed on this post.
case there are no rendered PDF's available, you can export PDF snapshots from within CAD prior to converting them.
you can also try other converters made for this purpose, like verydoc or PDF-tron.

I truly need help in Adobe Illustrator PDF. I have many small PNG files saved from lost vector line drawings.
The problem is that PDF scales up any image file (JPEG or PNG alike) when saved in Adobe Illustrator. Although such PNG images are as big as 1920 pixels width size, they are about 50 KB. But when exporting a PDF file, the PDF file becomes almost 9 MB. Is there a way to configure the Illustrator PDF to not alter the image type or size, but rather embedding it as is? I also don't want it linked to an outside file, but rather embedded as is, without scaling it up to 9 MB.
I looked through the PDF settings, but there isn't anything to give me the option to embed images without scaling up. Even setting it to 72 ppi doesn't make a big difference.

We used Adobe inDesign to design story books. We need both the PDF file as well as epub file. Since we all view in PDF during the process, the final clear product in PDF, when we export as epub file, it's huge. It all messed up the original design. What can we do?
Why did it happen?
I've worked on ONE project going from InDesign to ePub about two years ago - and you are right it is a mess. It didn't understand which local overrides to keep and practically every paragraph had style="localoverride1 localoverride2 substyle3 etc" in it. It was a mess to sort and clean up.
After that miserable experience we've found that it is better to view PDF and ePub as two separate products. Our workflow takes source XML and goes EITHER into InDesign OR through an XSLT to make an ePub. We no longer use InDesign to attempt to make ePubs - with an XSLT there is a LOT more control over the look and feel of the final product.
However if you are dead set on using InDesign - I've heard that it does fixed layout "epub" fairly well (basically it ends up being a bunch of images - it's not reflowable).

I am looking for PDF optimization techniques/pre-processing to convert Print ready PDF to media ready(Press PDF to web PDF).
Target devices for rendering the PDF are iOS and Android
Tools like Adobe Acrobat Pro, provides settings for such tasks like reduction of layers, merging of layers etc.
Expected output PDF shall have only three layers:
1) Text
2) Image
3) Special effects
We can do this by using pre-flight and thus selecting the layers and merge them.
Any steps to do this effectively, i don't want to do such optimization at page level manually.
Can i import layer (say multiple image.tiff) at multiple pages at a single run?
You can use Ghostscript for that.
If you want to do that via Ghostscript User interface, you can download Ghostscript Studio (IDE) and use this switches in the Ghostscript Processor:
! >> interaction-related parameters
-dBATCH ! keep gs out from going into interactive loop reading
-dNOPAUSE ! disables the prompt and pause at the end of each page
! >> device selection parameters
-sDEVICE = pdfwrite ! pdf device
-dPDFSETTINGS=/ebook
Also, take a look at this answer: Optimize PDF files (with Ghostscript or other)

Is it possible to convert an expanded blend to a simple lightweight vector shape, without all these inbetween paths of all n steps? It seems like a complicated object to work with since computer has to recalculate all the changes that are made to the inside paths.
Go to Object > Blend > Expand. Then, with all of the steps selected, go to Pathfinder and merge all the shapes together.
I don't believe there is a way to convert it back to a single vector shape as it would have to be able to translate the blend into either a linear gradient, radial gradient, or gradient mesh.
The beauty of blends is that they aren't bound by the same rules that allow the gradient or gradient mesh tools to work, and you can get some really awesome color blends across complicated shapes.

I have a PDF with the following text:
Localização
When I copy this text and paste, it gives me:
localizac¸ ˜ao
Any help is appreciate
Tks
For computer generated documents (not OCRd/scanned)
Some systems like LaTeX generates composed characters because the system's font doesn't contain (or support) such glyph in the current encoding. As consequence. They are generated on the fly using Composed Glyphs.
Making two glyphs look like one:
A + ´ -> Á
Because of this 'trick', the selectable PDF Text Information contains the two separated glyphs. But graphically they are both rendered at the same spot.
The quick solution:
Luckily, the generated character pairs do not happen naturally in a well written paragraph (maybe in any language). So is quite safe just search/replace them using a case-sensitive method. You can do it manually with your favorite text editor, or using a python script, etc. Automated or not, the principle of the solution is the same.
It is important to know how you are copying the text. If you are merely using a text editor and altering the underlying PDF code, you are going to have problems. PDF files are organized in a very complicated and non-human-readable way that require specialized programs to alter successfully. If you want to make this change, you will need to use a PDF editor to either edit the document, or generate a new document from scratch.
