Learning the Adobe Illustrator pen device is a simple ability of any expert designer that is graphic. It’s essential whenever you’re designing images that are vector-based fonts. Many developers utilize intuition to determine whenever a bend appears or “feels” appropriate. But often it simply appears odd and you also can’t find out why. Should you put an additional anchor? Take one out?

This design by Skilline utilizes plenty of perfect curves. Here’s exactly just just how it is done.

There’s actually a technology behind curves. In this specific article I’ll explain the mathematics behind curves, and explain to you simple tips to put it to use to help make your curves look smoother and more great looking.

A technique that is common expert CAD and font design software program is to utilize a visualization called a curvature brush to observe how razor- razor- razor- sharp or flat a bend is along its course.

Here’s an example of a curvature brush getting used in Fontlab VI to erase bumpy spots in a font:

The curvature brush could be the amber-colored bit at the side of each bend. As being a designer you should use the dimensions of the brush to evaluate exactly just how curvy the relative line is and where you can find discrepancies into the bend. (Notice within the gif that is above the bend gets smoother given that amber and red bits fall into line.)

To spell out exactly exactly exactly exactly how this visualization works, we’ll have to take a fast glance at how Bézier curves work.

Cubic Bézier curves —

Bézier curves were initially conceived individually by two French designers involved in the automotive industry — Paul de Casteljau from Citroën and Pierre Bézier employed by Renault. These curves turned into very helpful for designing the curved and aerodynamic forms necessary in automotive design.
