I’m using Adobe Illustrator CC 2017.
Is there a way to make Pencil or Brush tool snap to its lines and curves while drawing? I’m trying to draw a flower made of petals, and it’s very annoying to manually ensure that starting and ending points of each petal lie exactly on the curves of underlying ones.
Maybe there are better tools in Illustrator to draw this kind of picture? What is the best one for this case – pen, pencil, brush (I’m on Wacom Intuos Pro)?
A desire for precision generally means the Pencil and any “drawing” Brush won’t get you there. You can use the Pen Tool or shapes. The Pencil/Brush tool simply aren’t designed to be precise. They are focused more on natural drawing and all the imprecision and wonder that comes with that.
It’s possible to start with something simple like a single ellipse ….
…. and generate a “petal-like” image merely using
Effect > Distort & Transform > Transform…
You just have to “tweak” the settings to your liking.
Afterwards you can use
Object > Expand Appearance and you are left with simple, stacked, ellipses.
From here you can resize, rotate, recolor, the individual ellipses as desired.
(CS6 screenshots because that’s what I have launched. But it’s basically the same in CC.. the dialogs just look slightly different.)
