AutoNewbie Posted May 2, 2012 Share Posted May 2, 2012 OK guys I need a way to properly scale a drawing that I've pulled into AC.. Example, I get a drawing for customer in PDF that I have to trace into AC. Said PDF is marked 1/4 = 1. Up to this point I've been guessing at accuracy by measuring doors to 3'. I know this cannot be the prefered way, somebody please help me out.... Quote Link to comment Share on other sites More sharing options...
ReMark Posted May 2, 2012 Share Posted May 2, 2012 There are no dimensions actually shown on the PDF? Quote Link to comment Share on other sites More sharing options...
RobDraw Posted May 2, 2012 Share Posted May 2, 2012 If the PDF was made to scale, then using a scale factor of 48 for 1/4" plans will put it at the "correct" scale. Quote Link to comment Share on other sites More sharing options...

Dana W Posted May 2, 2012 Share Posted May 2, 2012 (edited) If the PDF was made to scale, then using a scale factor of 48 for 1/4" plans will put it at the "correct" scale. That is assuming the 'customer' didn't select Display, Extents, or Window, when plotting to some random paper size. If the pdf was plotted to scale, I'd first scale/stretch/shrink the PDF to a full size rectangle to match the document paper size, then apply the 48x scale factor. I've had pdf's converted to raster images not insert at their actual size. For instance, one I just converted from a 24x36 pdf to a 24x36 jpg, came in at 2.85 feet x 1.75 feet using insert > raster image reference. It is coming in to a civil ingineering drawing with inseretion units set to feet, dimension units set to feet, precision 1.0000.

I think you mean if it was not plotted to scale then you would have to go through that exercise. No need to do all that if you can verify that it was plotted to scale.

Am I missing a day of AutoCad class too? Quote Link to comment Share on other sites More sharing options...

Dana W Posted May 2, 2012 Share Posted May 2, 2012 Funny, I was wondering if english was your second language. Hey, I knows my werds reel good! Are there ways to import/insert a pdf that 2009 LT does not have? Is that why I have to convert mine to a raster before I can bring a pdf into my dwg?

RobDraw Posted May 2, 2012 Share Posted May 2, 2012 Yes, I think it started with 2011. Quote Link to comment Share on other sites More sharing options...
Dana W Posted May 2, 2012 Share Posted May 2, 2012 Yes, I think it started with 2011.OK, thanks. Now, I seem to remember it's in express tools, which 2009 LT does not have. Come to think of it, English is my second language. Redneck is my first. Quote Link to comment Share on other sites More sharing options...

Well, here's your rude awakening for the day. I ain't no dadgum female, and my favorite dee ziner is Ron Barret. I cain't post no picher of me, I'm in the witless protecshun program. The dog don't look sad. She is in dragon mode. She looks evil. Here's the full scale version. Skuze the photoshop eyes. They are really two colors, brown & blue. There was just rampant redeye goin on, so I repaired 'em. Quote Link to comment Share on other sites More sharing options...
daft vader Posted May 5, 2012 Share Posted May 5, 2012 Oh i'm sorry I just thought you were a Lady seeing your name was Dana W ? Thats one mean looking dog BTW Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 5, 2012 Share Posted May 5, 2012 MeasuredLength*sf=DesiredLength therefore sf=DesiredLength/MeasuredLength sf=scale factor Insert image Draw line over a known length (like dimensioned line or something of a standard size if not dimensioned - this is your DesiredLength) Dimension the line - this is your MeasuredLength Plug into the formula, scale and recheck. Back when I was in school this was taught to 14 or 15 year olds. Algebra used to be required knowledge to get into college (or design professions). I find it rather astonishing how often scaling questions come up here on a design forum. When I type up something like this I always worry that I'll make a simple mistake and need a flame suite, but isn't it easy enough to check?

Thats one mean looking dog BTW Yeah well, my momma had a crush on Dana Andrews, the actor from the '40s when I was born. What can I say. Daisy only looks tough. She's a lover, not a fighter. Not a mean molecule in her, anywhere. Quote Link to comment Share on other sites More sharing options...

Brian Not sure what that has to do with Dana Andrews and Pit Bulls...:lol: What was this thread about anyway? And then fix it all anyway, would be the next step. Those conversion programs leave a big pile of disjointed lines, sometimes even the text. Quote Link to comment Share on other sites More sharing options...
