Export 10K pixel limit - why?

[mschroeder]

If you are seriously trying to produce color elevation representations at scale then you need at least 600 DPI at 48" wide. That's 28.8K pixels in the long dimension. Why the 10K limit on exported images?

No, you seriously don't. 300 PPI does the job really well and for most situations 150 PPI is enough. If you have a 600 or 1200 or 2400 dpi printer they'll interpolate the difference when the file goes from pixels to dots. But to answer you're original question, the 10K limitations is probably memory driven but I don't really know.

If you need a high quality image, print to pdf then in photoshop you can convert to a jpg or other format.

Example:
1/8" elevation 11 story, 200' facade width in color. We need to see the brick coursing. (we do this in most situations). It's not a rendering nor is it photorealistic, it's an illustration drawing.

Problem:
Can't export an image with enough resolution to see brick, metal panel and stone coursing.

Workaround:
Export as dwg, import Illustrator, fill with color and add post elements and print.

Ideally we would be able to use the pantone colored model view right out of Revit, but because of this limitation (which seems arbitrary) it's not that easy.

Scott: you may have noticed that printing performance suffers dramatically with shading turned on (because of rasterization). But I've noticed that exporting 10K pixel images is so much faster than printing to a PDF or DWF (in computer memory). It takes over an hour to print a large color elevation when an export is less than a minute.

In order to see brick coursing one would want more than 2 rays cast over the thickness of coursing. At 1/8" scale and 150 DPI every inch of real world materials will be represented by only 3 rays. So 150 is not going to be enough to show coursing and even 300 may be on a low side. On the other hand you may try a simple workaround. Create duplicates of your view, preserve scale but set different cropping so as to split you view in multiple pieces. Then you can output high resolution jpegs of pieces keeping each of them under 10,000 memory limit and easily combine them together in a MS Paint or other graphics editing program.

Thanks guys. That's what we ended up doing.
