 Topic: Dwg to PDF NTS
Posted: 28.Feb.2012 at 19:24 |
Hi All,
I created D size title block. But when I plot it to Adobe PDF full size (1:1), the output is not to scale. For example, in my drawing I drew a 6" line and dim it as well. the final product is off but 1/4". Any suggestions? I've used DWG to PDF before but am having troubles with line weight. It has been a while since I used DWG to PDF, thus I can not recall if this give me the same problem (NTS).
Than-you in advance for any tips/suggestions...
Tpham

Set Page Scaling to "None".

Even with page scaling set to none PDFs often scale slightly off.
I won't plot directly to PDF anymore... there are simply too many quality issues that waste my time. What I will do however is plot to a dwf and *then* plot a pdf from there.
Try that with no page scaling and see what happens.
Dave.

I beg to differ. I just helped someone who experienced this problem with multiple sheet sizes and once page scaling was set to "none" the problem finally went away. Tested it myself using this person's own set of drawings so we could compare apples to apples.
If there are further scaling issues then the OP would need to look at the other parameters being used.

Hello, if you print a B format on a small printer your drawing will be shrinked with a certain % due to the margins ( ~5 % ).
When you "print" to PDF you will get X% more margins that will shrink your drawing again more ( ~+ 1.2 % # 5 x 1.2 = 6 % ).
If you want to print a PDF on a big plotter whith a roll you can enter a certain % like 104% for example to have your paper scalable printed exactly ( +/- 0.5 % ).
If you want to print on a small printer with margin you may not be abble to enter a certain %, and you will have to "print" to PDF a smaller rectangle including the margins and the % more for PDF.
You said your 6" line is off but 1/4", I think that YOUR printer + PDF % is : 1/4 / 6 ~4%.
You can calculate the % of your printer when printing an exact format to your printer or to PDF and looking at the "print scale" values.
Set to "fit to size", scale : customized and read :
1 inch = 0.XXXXXX units ( ~0.9867 from DWG to paper and ~0.9749 from DWG to PDF )

 When you create the PDF file are you working from a layout? You can get your PDF files to print to scale by setting "Page scaling" to "none". I've done it and so can you.

I'm still on the same page as Philippe... not talking about a huge scale error when printing directly to PDF, but enough that my old eyes can still detect it on a scale. Prints made directly from a DWG or DWF are spot on, as are PDFs from DWFs.
At least in my experience... and that's old school where *everything* was hand drawn and scaled.

Thank-you for the reponds. I tried John's method of setting the Scale to None when plotting from PDF and that seems to work. I've done this before but could not remember how to; after wasting 3 D size sheets it hits me... Palm face

I rest my case.
Good to hear you got the results you were looking for.
