Work Flow question - determining scale without dimensions

Like I said, scale the page in SU to 36 x 24 inches. then scale
Ok I think I follow you.
I can save the PDF as an image file.
Drag that into SU, scale to 36" on the long side - but then my image looks pretty crude as it's been scaled down (is that due to my current unit settings?)
But that's probably ok for now.
Use Tape Measure Tool to determine how many inches wide this elevation is, then do the math and punch in the result.. -

(edited) To be clearer, scale the paper to say 36 inch. Then use the measuring tool to measure a dimention in the drawing. Then when you have measured it apply the scaling maths and scale the drawing again so it is 1:1. Not ideal but should be OK for an su model.

If you do not have a high res converter try this it works online with no fees or sign up

And if you are using SUP it does support PDF's

It's the scaling down within SU where the quality of the image drops.
Makes sense because 36" x 24" is a small area in SU for a Plan that has 4 elevations within it. -
Surely there is something in the drawings that you can use as a known dimension. The height of a door, a brick, a roof tile, a stud. a joist etc etc
Can you show us an image.
Just checking also that there isn't a physical scale depiction with the scale. -
I guess i could use a door as a known dimension.

I'd be sending it back with a polite note telling them it is unusable with at least one known dimension.

Agreed but we are not sure of the circumstances. But I would think the source of the drawings could be got hold of, somebody paid for it. Could jman0war send a screenshot of the image in SU. I often have to deal with those images, and they are difficult to work with. However when they are blurred I draw sketchup lines in the center of the blurred line. Can we see how blurred it is with the requested screenshot?

He posted a link to the pdf.

If someone sent you plans for a house in PDF, that included Front, Left, Right, Rear Elevations and a RoofPlan.
But there were no dimensions included at all and the only information you had to go on was a scale ruler sort of information under the elevation title that says:
FRONT VIEW
1/4" = 1'-0"
(one quarter inch equals one foot).The other Elevations are a different scale:
....You could always download and use the Bluebeam Revu trial. It allows you the measure PDFs. You can even set the scale or calibrate to a known distance. Once the trial is over you can continue to use it in "Vu" mode. It's a very slick tool.

Thanks.
I used to use BlueBeam Revu years ago, mostly for the one click PDF conversion and a few Markup tools.
Looks like they've added functionality. -

Looks like they've added functionality.I only have the viewer but it's great to get dims off of PDFs. It'd be nice to be able to bring vector PDFs into SU (like I can in AutoCAD) but maybe one day.
Good luckGlenn
