These two fill methods can be used to fill closed shapes with pen paths. See the Hatch Fill documentation for more information. The lines are not connected, so it is not as efficient as the Hatches (rough) method below, but it does work in more circumstances. This extension creates a series of lines or cross hatches that can fill even complex shapes. The Eggbot Hatch fill extension is a newer method of creating filled regions. Where possible, design around having to fill regions. One final word before we get started: Plots where you fill solid regions can potentially take a long time with all that back-and-forth business. This tutorial assumes that you are familiar with Inkscape and basic object manipulation, including basic path operations like Union and Difference. In what follows, we'll show a few different ways to create such pen paths, what you might call "toolpaths" in machining terms. There are many possible approaches to this problem- brute force rastering, adaptive filling algorithms, cross-hatching, and on and on -and different approaches work best in different circumstances. So, what can you do it you actually want to fill a region with the pen? Clearly, you need to construct some path that the pen can follow through the entire filled region. Starting with the filled shapes on the left, the Eggbot will actually just plot their outlines, shown on the right.

The net result might be something like this: So, what happens if you ask your Eggbot to draw a filled regions? The Eggbot will simply draw the paths that make up the object, like it always does. This is like an old pen plotter it's very different from an inkjet or laser printer, where the entire surface is scanned back and forth. If you ask it to draw a circle, the pen tip actually moves in a circular path on the surface of the object that you're drawing on. The reason is simple: Egg-Bot is a vector printer that draws paths, not a raster printer that draws dots. However, it isn't actually that easy for the Eggbot to draw a filled region. In Inkscape, it's easy to color in any path region (say, a circle) with the paint-bucket tool (or solid fill in the Fill and Stroke pane). 4.3 Combining Interpolation and Stitch Paths.3.1.1 Workarounds for hollow geometry hatch fills.There is no Shape Builder in Inkscape so it is a little more manual of a process. A quick search didn’t bring up anything, so hopefully I’m not duplicating efforts here. In reading through this post, I figured that I wanted to see how to do something similar in Inkscape.
