I am reworking a map of Puerto Penasco Mexico amd having a scaling problem. The drawing is a .pdf to .dwg conversion and has all been redrawn.  On the drawing measurement is where 1st problem is.   Using measure on a line I get 1765 ft  on list it shows 1800 ft and on print it scales to 1500 ft.   I want all to be 1800 ft.
 
2nd problem is after printing a window it is leaving the window in black on the drawing view on the computer.
 
In all my years of Autocad LT use I have never had these problems.
 
All help is appresiated.  Bill Hale

Have you changed units precision in Dimstyle.?

Not that I know of.
 
Please what should each, that would effect this, be set at ?
Bill

Also I had ask about the last printed area showing on the drawing with a black background.

Is this such a dumb question that knowone wants to answer?
Or is it that ?
 
PLEASE HELP

PLEASE HELP[/QUOTE]Bill Send here any screenshot when you want to print. 

Which version of LT are you using?You can either freeze a layer, which you don't want to print, or set it to not print in layer control/manager (at least you can in ACAD 2005), but still be shown onscreen.Can you confirm the following :You have a line on a drawing, if you measure it, within LT it tells you that it's 1765 long..  If you select the element, it tells you that it's 1800 long.  If you print it, and then measure it it's 1500 long?ORYou measured a line from a pdf or other (physical) drawing and it's 1765.. or you know it's 1765.  But after conversion, within LT it's 1800 long.  Then it prints at 1500 long...If the latter.  I think you need to scale the items to make them resize in the drawing from 1800 to 1765.  Then you need to check the Layout tab to see if the drawing is printing at 1:100 or some known scale.  Or are you sending it to a file and then checking it?  It sounds like the scale has been adjusted in some unexpected way when it's printed..  or possibly you aren't printing from the Layout tab or maybe "fit to page"?

Bill,
I'll do it on my easy way.
Firstly, take 1800/1765 = 1.01983.
Then use this (1.01983) as a scale factor when you scale all your drawing (in model space). Your dwg now at 1:1.
 
You may know how to deal with Layout after this for plotting task.
If you do plotting by 'pick window' in model space, then you'll get black rectangle in your screen. Try plotting from Paper space instead of Model space.
 
good luck,
Rman.

I think Bill has worked this out for himself, but posted this information in another post....
