**Now it's time to draw something on the canvas: the kind of shape that suits spiro mode. Try drawing a circle, keeping it as neat as you can, and finishing in the starting node. As you draw you'll see a green line indicating your path, regardless of your current fill and stroke settings – don't worry, that's just a guideline that won't be visible when you've finished. Unless you have supernatural control over your muscles, the green path is likely to be bumpy and distorted; yet, on releasing the mouse button, it will be replaced with a nicely rounded circle. If your original path was extremely rough, you might not get a perfect circle, but the final shape will certainly be a lot smoother than your hand-drawn efforts.** | **Now it's time to draw something on the canvas: the kind of shape that suits spiro mode.

- | Maintenant, il est temps de dessiner quelque chose, le type de forme qui se prête bien aux splines spirographiques. Essayez de dessiner un cercle aussi régulier que possible en terminant votre tracé par son point de départ. À mesure que vous dessinez, vous verrez une ligne verte qui prévisualise votre tracé sans tenir compte du type de trait et du remplissage. Ne vous en faites pas : il s'agit juste d'un guide qui ne sera plus visible quand vous aurez terminé.

**Select the path you've drawn, and, in the Path Effects dialog, you should see that the Spiro Spline effect has been added. Toggle the visibility button (the eye-shaped icon) to see how the spiro version compares with your original path. Now try the process again with a different shape – a figure of eight, or a spiral. As you can see, for some shapes it's a lot easier to create something neat and smooth using spiro mode.** | **Select the path you've drawn, and, in the Path Effects dialog, you should see that the Spiro Spline effect has been added.

**When using the Bézier tool in spiro mode, the icon on the tool control bar is the same, but the drawing process is a little different. I usually suggest drawing Bézier paths as a series of straight line segments by single-clicking to place each node, then going back in Node Edit mode to add curves afterwards. If you take that approach with spiro mode enabled, you'll get a series of corner nodes which, as we've seen, don't really play a role in the spiro algorithm. Instead you need to click-and-drag as you place each node, in order to set the curves as you go along. Personally, I find this to be much harder to control, but give it a try to see if you're better at it than me! You can always lay down straight segments with spiro mode enabled, then explicitly change some points into cusp nodes afterwards. It's not a huge workflow improvement, | **When using the Bézier tool in spiro mode, the icon on the tool control bar is the same, but the drawing process is a little different.

**One big problem with having spiro buttons on these two tools it that it's easy for newcomers to Inkscape to enable them, then forget about it. A common question on the support forums is, “why can't I change the shape of my path using the node handles?” The answer is usually because the Spiro LPE has unintentionally been added, so watch out for that if you find yourself similarly stuck.** | **One big problem with having spiro buttons on these two tools it that it's easy for newcomers to Inkscape to enable them, then forget about it.
