```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
