    I have had some success in basic usage of Inkscape; however, the dxf file that I am importing. will not import when I chose the Read from file scaling choice. I can import it with the other two options but it changes the scaling.  The file contains clock parts that must remain the exact sizes provided for the clock to function properly once built.

    My ultimate goal is to import the file and delete part numbers on the drawing/file so that there are no toolpaths generated for those items.  I then export the parts and convert to SVG files and import into my EASEL software for running my CNC.  

    I test ran a part and it was cut per the drawing but at the wrong size and with holes where the part numbers were shown on the drawing (the bit was way too large to rout the actual part number so it showed up as holes)

    Thanks in advance for any suggestons and guidance on this issue.

    Please share a sample dxf file for evaluation.

    Thanks for reaching out to me, here is the actual dxf file I am working with.

    Scale looks ok using manual scale set to 1, as per the Help tab in the import dialog (presume units are mm).

    As I understand it, DXF scale from file is a bodge of a file format that does not specifically have units.

    I picked out a couple of other gears and Inkscape continues to change the size.  I have printed full size drawings that came with the dxf file and one of the gears I just did should be appx 4 7/8  "  and once I copied it from Inkscape and use a converter file to do a SVG file and imported it into Easel it imported at appx 7 1/2" .

    Attached screenshot from Easel shows the dimensions it was imported at.

    I decided to try one more time before I sent this and same results.

    If you are interested in exporting it from Inkscape and converting into a  SVG, I would be curious what the dimension would be.  If correct then something is going on with the import process into Easel.

    I don't expect you to dwell on this too long and already thank you for your time and effort so far.

    Kind regards

    The dxf dimensions are precise and open to correct scale in Inkscape using manual scale, validated with three CAD programs.

    • I also opened the dxf file in Inkscape, using units = mm, scale = 1.
    • I set the Inkscape Document properties to mm.
    • I copied a gear from the open file into its own Inkscape document (units = mm) and saved as SVG. That gear in Inkscape measured 137mm.
    • I imported the saved gear file into Easel online and that geometry is also 137mm.

    Please share your Inkscape SVG file after importing your dxf file.

    Thank you again for your efforts.  May be a day or two before I can jump back into this and I will be glad to give you an update.

    Hi Tyler,

    I  sent a reply email out yesterday, but it must be out in cyberspace as it did not show up in my sent box.  If you did receive it then I apologize for this follow up. 

    I spent a few hours over the last couple of days on this and I am still not getting the correct measurements loaded into Easel.  I changed the parameters in Inkscape as you mentioned and believe that wherever it called for a unit 'of measurement, i changed it to mm in Inkscape.  I must be having the 'can't see the forest for the tree' moment and not converting something that I think I am / or should be.  

    Anyhow, I appreciate all of your time and suggestions so far and would understand if you want to call it quits on your assistance.  Should you wish to continue, I would be glad to compensate you for your time and effort.  At this time I don't want to attempt to do a course to learn Inkscape or CAD as this is likely the only dxf file that I expect to use that requires the dimensions be exact once I clean up the part markings and separate the parts into smaller workable files as Easel stalls on  me when I try to import it as one file.

    If you are interested in assisting further, I would be open to being walked through the steps while on a phone call or doing a screen/computer share so I could watch the commands and hopefully understand what I have been doing wrong.

    Finally!!  I was not exporting the parts correctly and once I figured that out, it became very easy to do.  I believed all along that I was overthinking this or overlooking something!

    Thanks again for your support.
