Export To What?
-
I only use .png.

I only use .png also.
It is "lossless" meaning it never compresses the image data. Even .jpg stored at the best quality setting will still reduce the pixel data slightly. And over time, resaving and resaving, little by little, the .jpg will degrade ever so slightly.
Never happens at all with .png.
Also, .png is capable of using the alpha channel. It can store transparent pixels, if you have any, and your machine can export them (PC SketchUp can not export them). But Mac's can.
I do however export as jpg when I'm exporting for certain co-workers who freak out if they get an image that is not in .jpg format.

it's always vector for me... dwg and for adobe that works well.

Solo, Chris and Kristoff,
Thank you for taking time to respond. Are any of you knowledgeble about the .eps format. I've come across some large images in that format and wondering what makes that special for large graphics?

I remember back in the day .eps was only on Mac's used mostly for DTP (desk top publishing), Windows equivalent was .tiff, these days they can both be used on both platforms, I occasionally use .tiff when sending renders to clients (uncompressed).
I'm not sure if one has an advantage over the other or is they are still commonly used as they were. -
I'd agree. I typically use .png. It's lossless like TIF but the file sizes are typically much smaller. I work with a guy who only uses TIF though. His reasoning is that .png's don't save color profile information (IF that's true, I've never run into an issue with it).

Think PNGs save colour profiles. At least, I can have them.

TIFF files come in many variations - mostly to do with compression methods. All are lossless so the variant has no effect on quality, and there is really no reason to use uncompressed unless the receiver for some obscure reason demands it. LZW compression comes closest to PNG in size as the compression method is the same in both formats. TIFF supports layers and channels, I don't think PNG does. PNG also doesn't have a bitmap mode, so usually I store scanned black and white drawings as TIFFs.
Generally RGB is the preferred colour space - CMYK is intended for traditional colour separated printing press production, and its colour gamut is smaller. The Windows version of SU doesn't support CMYK at all.

I've had models with CMYK mode JPEGs which displayed fine under SU Windows. I noticed this because V-Ray for SketchUp would not render CMYK mode textures.

Krisidious,
I mostly export dwg as well. However, the quantity of entities KILLS me. The SketchUp drawing below has 49,595 entities. I believe this is because dwg does not support Bezier curves or ellipses. All arcs, ellipses, curves and many lines are broken into segments. That is, a simple circle (a single entity item in some vector drawing programs) breaks down to 24 entities in SketchUp. And, the quality of the dwg export is not really good - even for relatively simple objects. Many lines go missing, corners don't meet, etc. I've tested this in Corel Designer and Illustrator. If I have a choice, I bring 3D models into SolidWorks for export as dwg. The filters are fantastic and the results are nearly perfect. Other programs with similar results to what I get with SketchUp (high entity, bad quality vector export) include QuadriSpace, Right Hemisphere (Deep Exploration), and Adobe 3D.
