Dear all member!
I'm very new to design software and I'm trying to use InkScape to create some DXF files that can be cut out using a laser cutter.
I'm trying to create just some basic numbers and letters, but they need to be a specific dimension(4 inches tall, 2 inches wide at widest point).
I tried just making them by hand but all of the segments were seperate and they weren't perfectly accurate.
Could someone give me a basic rundown of how to create these types of files? Perhaps explain how these files are read by the machine?
Any general information about making these types of files using Inkscape would be greatly appreciated, I'm very lost currently.

Thanks in advance!

Might find some info here: http://www.inkscapecuttingdesign.com/smf/index.php. Also look into your hardware and software documentation. Might find some tutorials or instructions. Maybe they even have a support website?

To make precise drawings in Inkscape, I use either guides or a pixel grid and snapping. If your drawing is all separate segments, it makes me wonder if you might be using the Pencil tool. The Pen/Bezier tool is the ultimate vector path tool, and really most advanced Inkscape users and professionals use it predominantly.

Briefly, you click where you want to place a node. If you click in the tiny box at the beginning of the path, it will close the path, and prevent having separate segments (unless you need an open path, for some reason -- then double-click to end the path). Or you can use the Node tool and join the nodes of paths that aren't closed. Here's a tutorial I wrote -- very long, a lot of text to read, but it gives a good introduction to vector paths. How to Draw a "Line" with Inkscape

Be sure to save an SVG file, before you save as DXF. It will be easier to edit the SVG with Inkscape, than editing the DXF file (as far as I understand, although I could be wrong about that). Creating DXF file is as simple as taking your Inkscape drawing and File menu > Save As > DXF.
