Re: Controlling scale of Graphics on paper

I would like to use Mathematica to make printed templates of various 

kinds.  



In one use, a complicated shape is generated mathematically and 

displayed using Graphics or Show, the plot is printed on paper, the 

paper is glued to a piece of wood, which is cut and drilled to the lines 

and center-points.  This requires the ability to control the on-paper 

scale factor, so that a length of 1.0 in a line ends up being one inch 

(or one centimeter) on paper.  



I assume that this is possible, but have not found anything relevant in 

the online documentation.  What I have done is used Mathematica to make 

dolls of machine parts; in this case it was sufficient that all be in 

the same scale, which was achieved using ImageSize->72*6 directives, but 

ImageSize doesn't speak directly to the issue of scale on paper.



It may be that ImageSize->{w,h} can be used, but there is some math 

required.



So, my question is how best to achieve a specified scale on paper.  



TIA,



Joe Gwinn



Dear Joe,



There had been once a discussion on this subject here, though I have no reference to it. The outcome consists in the relation: 

  1 cm = 35.7744 pts. Then if you need to specify the size of your graphics say, 10 cm x 15 cm, you could do the following:



Plot[Sin[x],{x,-Ï?,Ï?},ImageSizeâ??35.7744*{10,15},AspectRatioâ??1]



Have fun, Alexei
