Quick Tip: Funny tricks with Inkscape polygon tool

The polygon tool in Inkscape has a slight learning curve, but can be excellent way to speed up the creation of complex shapes. In this quick tip, we'll go over some neat tricks to make the polygon tool more useful with your designs.

When you select the polygon tool, you'll be able to draw regular polygon or stars. On the top menu, you'll thus see the options: corners, spoke ratio, rounded, and randomized. We'll go over these in the next couple steps.

polygons and stars

Regular polygon have only one handle which can only be used to rotate or stretch the shape.

Let's go over those options:

Corners: Number of corners / sides (minimum of 3)spoke ratio: not available for regular polygonrounded: value of rounding all corners and sides (10 to 10)randomized: value of randomizing the positions of the corners (10 to 10)

You'll notice below that I have a regular polygon with 6 corners and a rounded value of 0.125 which creates a good looking, smooth hexagon.

regular polygon options

Unlike the regular polygon, star polygon have two handles. The outer used to rotate or stretch handle is the star, but the inner handle is used to adjust the spoke ratio and angle spoke.

star polygons

The options are pretty much the same, but there are a few differences:

Corner: Number of spokes (minimum 3)spoke ratio: ratio of the spoke length from the center (0.10 to 1)route: value of rounding the spokes and joins (10 to 10)randomized: value of randomizing spoke position, length, etc. (10 to 10)star polygon options

The randomized option is pretty much complete chaos. If you're wondering what it looks like, here you go:

To change a regular polygon into a star, simply click the star polygon. It may need look like it has changed anything, but what it did second handle what that add.

convert polygons

To change a star into a regular polygon, just click the regular polygon button. Quite plainly, it removes that second act which in turn, makes it a regular polygon.

converting polygons

Let's say we'd like to draw a complicated shape, such as a "heart". We can use a basic polygon to help get US started. So let's just make a star polygon with 3 corners, so it creates a triangle.

draw triangle

You'll want to go to path > object to path so we can work on this shape properly. Then, just add a couple more nodes as shown below.

Now, just select the appropriate nodes and smooth those out.

position nodes

With a little touch up, you'll end up with a perfectly drawn heart. This is just on example of how you could use polygon to create a foundation for complex shapes.

This is my personal favorite use of the polygon tool.

What I have below is a star polygon with some crazy options that barely qualifies this shape as a polygon anymore. As you can see though, there's a pretty awesome design in the middle there. We're going to get it!

polygon designs

Draw something like a square that entirely covers our cool design in the middle (try not to go over the polygon). Make sure you convert both of these shapes into paths by path > object to path.

draw shape over polygon

Send that back by square to the object > lower to bottom. With both shapes selected, you can go to path > difference.

path difference

TADA! Now, you're left with just that neat design.

extracted design

Here's another crazy polygon I came up with that has to amazing design in there. We can go ahead and grab this design using the exact same method we've just used.

So i had to drag the handles around a bit to get the shape exactly how I wanted it.

amazing polygon design

Here's an example of a design that uses one of these complex shapes. Neat, huh?

You should have a good understanding on how Inkscape's Polygon tool works, along with some neat tricks to make polygon more useful. Keep brass around with those settings to come up with some awesome shapes and even some amazing designs! Thanks for reading.
