It's pretty clear what has happened: parts of the path have been pushed away from the tool as it moved across the shape. First the left side was pushed into the middle then, as the tool passed over the boundary of the shape, the right side was pushed further out. Essentially the path is distorted in the direction that the tool is moved, and this tweak actually feels a lot like pushing watercolor paint around on a page by blowing through a drinking straw. The amount of distortion depends not only on the Width and Force parameters, but also on the speed at which you move the tool. If you move it slowly enough you can even cut an object into separate pieces.** | It's pretty clear what has happened: parts of the path have been pushed away from the tool as it moved across the shape.

This is useful for sculpting the shape of a path. By moving the tool around the outside of the path, you can pull it outwards – making it bigger. Moving it around the inside of the path, on the other hand, pulls it inwards – making it smaller. Holding Shift simply reverses the direction of the pull. Try using this to shave away part of an object, or to make it gently bulge outwards. If you go too far in one direction either hold Shift, or move the cursor from outside the shape to inside, or vice versa.** | This is useful for sculpting the shape of a path.

I suppose the Roughen tweak is living up to its name in this case. The path certainly looks rougher in parts. But because the effect is stronger towards the center of the tool, the roughness hasn't been applied evenly around the path. Trying to draw the tool over the outline in an effort to spread the effect just results in it cancelling itself out again, producing a less rough result. To make matters worse, the rough areas now have huge numbers of nodes – this example resulted in our 10 node star growing to almost 2,000 nodes!** | I suppose the Roughen tweak is living up to its name in this case.

Before we can even think about creating new nodes, we need to ensure that our object is a path. In the case of our example star, it's not. That's not a problem as we've converted plenty of shapes to paths in the past, so it should be a familiar operation by now: just select the object and use Path > Object to Path (Shift-Ctrl-C). Now we've got a star-shaped path made up of 10 nodes, but if we try to jitter those few nodes, all we'll succeed in doing is slightly distorting the shape.** | Before we can even think about creating new nodes, we need to ensure that our object is a path.

+ | Les deux commandes suivantes déterminent si les positions des nœuds ou de leurs poignées seront décalées. Décaler les nœuds donne une ligne plus déformée ; décaler les poignées produit plus de pointes et des transitions nettes ; choisir les deux vous donnera une ligne plus déformée qui a aussi des pointes et des angles vifs. Le dernier contrôle détermine simplement la façon dont les changements aléatoires sont sélectionnés. Si cette case est cochée, ils suivront la « courbe en cloche » d'une distribution normale, ce qui signifie que des petites variations sont plus probables que des grandes. En théorie, cela peut donner un aspect plus naturel, mais dans la pratique, la différence n'est pas vraiment perceptible dans de nombreux cas. | ||

As I mentioned last time, I rarely make use of the tweak tool. I find it too difficult to control accurately, with the effects often being far too subtle or far too strong. Using a pressure sensitive graphics tablet can certainly help, as it's easier to dynamically modify the Force as you work, but often – as in the case of the Roughen example – you can get better results using other methods.** | As I mentioned last time, I rarely make use of the tweak tool.
