Allows you to define the precise page size for the output
Default: Automatic
By default, pdf2cad automatically uses the page size defined in the PDF original to calculate the number of measurement units for the DXF output. Only change this setting in the following circumstances:
When part of the drawing is missing from the DXF file. In this case choose either a pre-defined size that matches that of the PDF original, set a custom size or uncheck the "Convert PDF files to pages" option so that pdf2cad crops the DXF based on the drawing objects on the page. If choosing a Custom Size, width and height must be set in millimeters: 1 inch = 25.4 millimeters.
If you want to crop the DXF output based on the drawing objects on the page, so that any unnecessary white space around the drawing is eliminated.
IMPORTANT!
When you generate a PDF file from a CAD application, the drawing is scaled to paper/print dimensions. Because the PDF file no longer retains the original CAD measurements, pdf2cad must extrapolate the unit measurements that DXF requires. This means that the scaling of the DXF result may not be what you expect. In this case you will have to scale the drawing in your target application to achieve the dimensions you require. Note: pdf2cad uses a ratio of 72 units per inch on the PDF to calculate units for the DXF. The value of 72 was arbitrarily chosen to match common screen resolution.
