Drawing a Hachure in Adobe Illustrator
Hachures – I love ‘em! They are beautiful to look at and transform any map into a work of art. Unfortunately, I do most of my map making using GIS, where their non-numerical nature doesn’t allow for the analysis of slope, height, etc. However, I also do a lot of map redrawing, which often gives me the chance to lay down some serious hachures.
Adobe Illustrator doesn’t have any preset brushes or effects that would make drawing hachures an easy task. Creating a single hachure is no big deal, but copying, pasting, resizing and aligning each one? Are you serious? No, the easiest way is to create a custom brush that will apply your hachure design to all selected lines. So far I’ve made several hachure brushes and the two examples below are the ones I use most; a simple one and one with a fattened base.
How to use the custom hachure brushes
- Download the brush library from here
- Open Adobe Illustrator
- Open the Brushes window (F5 or Window > Brushes)
- Click the ‘Brush Libraries Menu’ icon at the bottom of the Brushes window
- Select ‘Other Library…’
- Browse to the location where you saved the brushes, select the file and click open
Draw your lines ‘upslope’, that is, from the point to the base. Once you have drawn all your lines, select them and click on your choice of hachure brush from the brushes window. You may find that you need to adjust the line thickness to get these looking right for your drawing, but with a little tweaking they can be very effective.
Hachure up, baby!
