...and I don't have a way to read a DXF file.

What about exporting to SVG and printing that?

I can print the SVG file through Internet Explorer, but the scale is wrong. It looks correct in OpenSCAD, but it prints way too small.

Also tried through Pdf Creator, but again too small.

OpenSCAD shows it at about 100mm tall, which is the correct height. It prints at about 1 inch tall.

module profile()
{    
 translate([600,0,0]) rotate(-2.2) square([100,2600]);
 translate([1000,2800,0])  square([100,1300]);
 translate([1077,2800,0])rotate(129)  square([100,415]);    
}

$fa = 5;
$fs = 0.1;

projection()
rotate([90,0,0])
scale(25.4/1000) //mm --> inch
rotate_extrude()
 profile() ;

What's the expectation here? OpenSCAD has no internal
units currently, so this needs to either match the
expectation of the next tools (e.g. for STL which has
no units either) or match the fixed export units that
are set when exporting the file (like for SVG).

The dev snapshot will currently always force export
in mm for SVG. Not sure what the last release version
does.

ciao,
  Torsten.

I printed some drill templates by laying out the holes as small circles in Openscad, exporting as DXF, loading in Inkscape and printing. I didn't have to do anything and the scale came out correct. Then I just taped the printed paper to the object I wanted to drill and used a centre punch to mark all the holes through the paper.

I was hoping to print a scale version, which is what a DXF file would allow, I believe.

Solved. I was able to import the DXF into my PCB software (Diptrace). Specified the units (mm) and itprinted just right.

Thanks guys.
