ol4f Posted October 3, 2015 Share Posted October 3, 2015 Hi, any idea how to draw a sine wave in AD? In Illustrator i found the zigzag filter which does a nice job. Maybe there is something similar in AD? Thanks for your help. Quote Link to comment Share on other sites More sharing options...
A_B_C Posted October 3, 2015 Share Posted October 3, 2015 Use Apple’s utility Grapher with y = sin x, export as PDF, open in Affinity Designer and use the curve either as a template for your own drawing or the (heavily node-laden) output of Grapher itself … okay, this is a somewhat dirty method … LOL … ;) Sine.afdesign ronnyb 1 Quote Link to comment Share on other sites More sharing options...
ol4f Posted October 3, 2015 Author Share Posted October 3, 2015 thanks for the fast answer. I have tried this before and the millions of nodes are not very comfortable. I also tried the .svg file from Wikipedia which is better than the Grapher Version and works only with a few nodes. But the Illustrator version is the most elegant one with only one node on every peak. sinefromillustrator.afdesign Quote Link to comment Share on other sites More sharing options...
A_B_C Posted October 3, 2015 Share Posted October 3, 2015 Thank you for sharing this one, ol4f … :) I do agree. The million nodes sine from Grapher is indeed not very beautiful. Some years ago I did some pattern designs based on sine waves for a wall decoration, and I chose just the way I described. Exported the sine graph from Grapher and drew it on the basis of that file in my favourite Ad*be program … it’s a somewhat cumbersome method. The sore point is that sine waves (representations of the graphs of sine functions) cannot be represented exactly by Bézier curves … But you can use Grapher in a more efficient way to help you with redrawing your sine wave. Simply create guide lines for the important points by using the respective equations in Grapher (my first screen shot) and export your sine together with these guide lines. Then snap guides in Affinity Designer to your Grapher guide lines and delete these lines. Lastly, draw the sine wave (second screen shot) … note that you have to catch just the values for arguments from, say, 0.5pi to 1.5pi (simplest choice, in my opinion). You can clone, flip and stitch your whole sine together then … :) A quick attempt is shown below. Cheers, Alex Sine.afdesign ol4f 1 Quote Link to comment Share on other sites More sharing options...

A_B_C Posted October 4, 2015 Share Posted October 4, 2015 That’s very interesting, Peter … :) Create a grid as shown in my screen shot, draw a zig-zag line and convert the nodes to smooth connections … the result comes pretty close to a sine wave … :o Sine_Peter.afdesign MacGueurle 1 Quote Link to comment Share on other sites More sharing options...
