Curved Sine Wave


Curved Sine Wave
#1
I'm authoring the following pattern:
[Image: 25269pb001__81269.1538605146.jpg?c=2&imbypass=on]
The part is almost ready except that I'm not satisfied with the curved sine wave on the round border.
I'm sure there is a way to do it better using an appropriate tool but I don't know which one. Would you have any suggestions on how to design it?

Here are my files so far.

Maybe something like this?
Create a centre point. Split the longer sides. "Action/Split N-times"
Set the Manipulator on the centre vertex. Select all the vertices around and Rotate the surface.

Hi Vincent,


here's a small spreadsheet that calculates a sinus wave, unfortunately it is not very flexible, but it might get you the idea

I have attached the result as well.
   

Let me know if you want a different amplitude

Thanks for the spreadsheet, it helps for sure.
I found the line too thick so I modified the width to 0.25 and amplitude to 0.375

I will submit this on PT now.

Thanks for authoring this. I've updated my Modular Buildings missing parts list.

Thanks to have authoring this part, I need 2 of it for the set 10255 - Assembly Square.

A question about the color choice. How do you choose the right color ?
Usually, I use a scanner and a small tool to found the right color. For this part the pink area is closer magenta with this method.

To be honest I rely on my sight and I compare Ldraw colors with pattern pictures.
But indeed I have some doubts about the colors I used for that part.

I made a second test and I agree your choice, dark pink instead of magenta.
