DXF files are not visibe when imported

Can you share a file and also make a screenshot of your import settings?

Please upload those to a file hoster of your choice, and share the links. Attachments are not supported here.

I have put the files requested in a folder called Inkscape in my dropbox.
The link is

Hope this helps

Please convert the file(s) into the supported DXF version, or already export them in the optimal format.

Inkscape supports DXF R13 (and higher, it seems) for opening (see the dropdown in the File > Open dialog).

Opening the file in LibreCad, saving as DXF R14, and then reopening in Inkscape worked for me.

At least, mostly. Not perfectly, some shapes seem to be missing or moved, at the ends.

I have done what you suggested and yes it works apart from the missing bits. The missing bits (coloured red) came from a different DXF and were pasted on. I suspect this could be why they are not displayed correctly.
However, the drawing is opening in Inkscape approximately 4 times its original size. The original drawing is roughly 158x44 mm. It seems we have another problem.

Thank you for your help and effort.

1. I get a different result, but I am using Inkscape 0.92.x, the stable development branch. Are you using 0.92.3, or some earlier Inkscape version? Note that I *open* the file with Inkscape, I do not import it.

2. As another test, I saved as MakerCAM SVG from LibreCAD. This keeps all parts in the file, but I get a size of 168 mm, which needs to be divided by 96, then multiplied by 90, to get the correct size. This is because the other program seems to assume a resolution of 90 dpi, while Inkscape uses the CSS standard resolution of 96 dpi.

3. (Best option so far) However, I've found a better option. I saved as pdf from LibreCAD.
This:

- keeps all elements
- imports in the correct size in Inkscape
- adds groups, and due to inefficient code in Inkscape, ungrouping takes ... eternally. Don't use Inkscape's normal ungroup if you need to ungroup a group that holds many (> 100) objects! Use Extensions > Arrange > Deep Ungroup instead, that is much, much more efficient.

Thank you Hachmann.
I am using version 0.92.
Your solution version 3 works. All elements are present and the size is correct! Hooray!
However (isn’t there always a however?) I need to make all the lines in the drawing red, or my laser software will only cut the red bits and engrave the rest.
I know this seems bizarre, but the idea is to be able to engrave and cut all in the same run.

Sorry to be a nuisance, but thanks to your help I am making progress and learning at the same time.
Thanks again for your help and support.

Can you rephrase the question? I don't understand what must be red and black etc.

I assume you already know how to select everything, and to change the selection's stroke color, so you're probably asking for something else.

Sorry Hachmann, I do know how to change the stroke color.
I had completely forgotten with all the different software being used.

The problem is solved! I just need to remember how to do it (I do not always have internet access - I live on a boat).

Thank you for your help.
