Exporting to PDF-- image quality problem

Kenny · 13 Dec 2007, 16:06

Make sure you have the high quality settings on in the print dialogue box. The highest quality setting is the vector based HLR. Check the 'use high accuracy' HLR
box when printing. The only problem with this is that it doesn't
display textures or shadows. If using the non HLR settings to display
textures and shadows, for best results be sure to set the print quality to ultra high defintion.

Thanks for the advice. BTW, it's not just printing-- the file looks bad on my screen even before I print. I don't think adjusting the print options should affect that, should it?

Gaieus · 13 Dec 2007, 16:18

Could you show a screenshot of what it looks like?

Kenny · 13 Dec 2007, 16:24

The print settings shouldn't affect the display. Make sure you have got hardware accelaration on (Window, Preferences, Open GL)

Is that in SketchUP or Acrobat?

I have one, but I don't know how to post a file here. Is there some dummy site on this MB I can upload to and then link to from here?

Here we have an attachment server:

Thanks, Gaieus. Let's see if this works. Sketch-up floor plan on the left, what the image looks like after export to Acrobat on the right:

Bathroom Floor Plan

BTW, I did have those setting correct, Kenny.

You have some funny large value set in the Profile width box. Setting it to Match Screen display is usually enough

Please don't use the BMP format for image attachments, the file sizes are enormous and they take ages to load

Sorry about that. I just used the screen-capture program that Gaieus recommended in an earlier thread: "Gadwin PrintScreen". I guess it defaults to .bmp. Can I still use that and convert to another format that doesn't create such large files?

I'll fool around with your recommendations, but I'm not quite sure I understand what you're getting at. I set the drawing size parameters so that it would be to scale at 1/4" = 1' in Acrobat.

Have you tried to export from LayOut?

Just tried it. Same result-- bad.

Anssii: I checked again, and I do have the "Profile Lines" section set to "Match screen display". I'm not sure what the "profile width" box is, though. Did you mean "Drawing Size width" box?

Anssi · 13 Dec 2007, 20:30

Sorry, my bad memory. Of course I meant the Profile lines box(and Section Lines, too)

I cannot say right away what the problem is now. I remember once getting the same result, but not what caused it. Let's think about it...

Well-you say you adjust the page size to get the right scale. For me it works the other way round. I set the scale, and the page size adjusts itself (as I tab out of the scale box). I never touch the page size settings unless I want output that is not to scale.

Can you attach your skp file?

Sorry if I didn't make that clear. I set the Drawing Size "scale" parameters* and let the "size" parameters adjust themselves.

*This was not easy, though, as SketchUp kept trying to tell me I was exceeding the page size limit. I had to do it in a certain order, or it would reject it.

Hmmm. Having trouble doing that. I copied my SketchUp file into the sketchucation newbie folder, but when I click on it, I don't get a URL address to link to-- just and empty (Mozilla) browser page. It worked fine with that .bmp file I did earlier. If you want to look at it, it's in the newbie folder under "Bathroom Floor Plan".

I had no problem exporting. This is what my Export dialog looked like

And this is the PDF I got:

I didn't either!

But then I figured out what the problem is. I have to use 2D export to get the .pdf option, and in that case it only exports what's visible on the screen. In order for me to get the whole floorplan on the screen, I have to make it much smaller. In that case, you don't get individual lines-- it's like you did a screen capture, and you lose all the detail.

Try it again with that bathroom floorplan shrunk down like this (don't adjust the magnification):

Interestingly, this seems to happen the same way when you use "insert" in LayOut. You only get what's visible on the screen from the .skp file. And if you shrink it down enough to get an entire floorplan (in my case a set of floorplans), you just end up with a blurry image.

Maybe I'm missing something, but if you can't export to Acrobat at scale, and at 24x36 paper size, then it's not much use in a real-world situation, because that's what's you're going to have to give to builders and city planning depts., etc. I have to believe that this has been worked out, and that I am missing something.

Gaieus · 14 Dec 2007, 08:58

I cannot jump into the discussion now as I'm not at home with my Pro version to export PDF.

So I just about Gadwin Print screen; you can select the output file type - jpg (as it can be compressed) is the smallest.

Yes, you are missing something. The point of the profile settings is that the "match screen" setting does literally that: the profile line thickness is set in proportion of the screen display, so in your case, if you magnify the plan to four feet wide, the profile thicknesses will follow suit. So you must just untick the "match screen" setting, and decide yourself how wide you want your lines to be. Attached is the setting you probably used

and the PDF you probably got
testi1.pdf
Then my new settings, with all lines at .25 mm thickness

And the result-see next post, it seems to limit to 3 attachments
