How do I manage or customize the size of the svg image from inches to meters or mm

[kinoy]

Through ecma scripting im able to export dwg file to svg file. while exporting the svg file is being converted in default size of inches.
example
<svg width="151.1032682882168in" height="151.1032682271798in" viewBox="-0.8053099276711326 -14.255580999176 15.11032682882168 15.11032682271798" version="1.1" xmlns="http://www.w3.org/2000/svg" style="stroke-linecap:round;stroke-linejoin:round;fill:none">

however through the qcad tool of edit ->drawing preferences-> drawing unit one can change the drawingunit to either meters or millimeters.

example
<svg width="755.516341441084mm" height="755.516341135899mm" viewBox="-805.3099276711326 -14255.580999176 15110.32682882168 15110.32682271798" version="1.1" xmlns="http://www.w3.org/2000/svg" style="stroke-linecap:round;stroke-linejoin:round;fill:none">


is there any way to to it through ecmascripting. Have set the following property through ecma scripting but it is giving the default output in inches.

properties["unit"] = "mm";

var exporter = new SvgExporter(document,properties);

You can set the document unit using RDocument::setUnit, e.g.:

Code: Select all

document.setUnit(RS.Millimeter);

Thank you very much for the reply .

I have added document.setUnit(RS.Millimeter); and also properties["unit"] = RS.Millimeter; But the output file is still showing the same inches. Is there anything else which has to be added. Below is the code excerpt.

var document = new RDocument(storage, spatialIndex);
document.setUnit(RS.Millimeter);
var di = new RDocumentInterface(document);
di.importFile(inputFile);



var properties =[];
properties["unit"] = RS.Millimeter;
var exporter = new SvgExporter(document,properties);
exporter.exportFile(outputFile);

The drawing unit is stored in the file you are importing. So after importing a file, the document unit is set to the unit stored in the drawing file. I.e. setting the unit before the import does not have any effect at all.
