Question: I have converted a PDF drawing to a AutoCAD DXF file . how should i change the scale of drawing? I have converted a PDF file to an Dxf file but when i am measuring all dimensions are diff then actual dimensions in drawing. so please tell me how can I change the scale of drawing.
Answer: If a dimension says 10m and the actual measurement is 5 units, you have to modify your dimension style and adjust the DIMLFAC system variable. Decrease the size to half or calculate the scale factor by dividing the actual value with the displayed value. Use the DISTANCE command when checking measurements, not the DIMENSION command.DIMLFAC can be manually adjusted in the "Modify Dimension Style" dialog box, under "Primary Units" tab in the " Measurement Scale" group. Change the "Scale Factor" value. And there is also another methods that you can use software to convert VeryDOC PDF to DWG Converter can help you convert and change the scale of drawing in one command line.directly.
If you need to do the conversion and changing in the easiest way, maybe you can have a free trial of this software. Please check more information of this software on homepage. In the following part, I will show you how to use this software.
- This software is Window command line version software, when downloading finishes, there will be a zip file. Please extract it to some folder then you can find the executable file.
- When call this software from MS Dos Windows, please refer to the usage and examples in readme.txt.
Step 2. Convertand change the scale of drawing.
- Here is the usage for your reference: pdf2dwg [options] <pdf-file> [<out-file>]
- When converting PDF to AutoCAD and scale output drawing, please refer to the following command line templates.
pdf2dwg.exe -xscale 0.5 -yscale 0.5 C:\test.pdf C:\out.dxf
When inputting command line, please input options of parameters first then input the full path of input PDF file the the output PDF file. When changing scale of PDF, you may use the following parameters. This software allows you to scale output CAD file from X and Y directions.
-xscale <fp> : scale by a factor in x-direction
-yscale <fp> : scale by a factor in y-direction
By this software, you can also do lots of work, like rotating output by any degree (0-360 degree), map colors to layers in CAD drawing and others. More functions could be found in readme.txt. During the using, if you have any question, please contact us as soon as possible.
