Inkscape crop out of page11/10/2022 ![]() ![]() In the middle set of four shapes, we've applied the hatch procedure as outlined above. The four original (filled) shapes are on the left: A star, a square, a square with a star punched out- essentially a hollow, ring-shaped fill region - and a smaller square with a star punched out (a set of multiple disjoint regions). This "live path effect" hatching method can handle paths that consist of multiple disjoint regions, for example, a set of stars or non-intersecting circles, but it does not work with "hollow" regions, for example a ring or washer (2D torus) shape. You may also need to use the Fill & Stroke panel to set the stroke to be a visible pen and the fill to "none." A separate tutorial on using this method (skipping the extension) can be found here. Use the "edit paths by node" tool to set the angle, spacing, and bending of the lines.(Optional this changes the hatch parameters to pleasant defaults.) Use the extension to set defaults: Extensions>Eggbot>Preset hatch for fills. ![]() Apply new effect: Hatches (rough) and click "+Add".Open the live path effect editor: Path>Path Effect Editor.This method is described in detail in our smiley face tutorial. 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. #Inkscape crop out of page seriesThis 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).
