Grasshopper

algorithmic modeling for Rhino

basics in creating a mandala

Hello,

I have a project to generate a mandala in grasshopper.

I just started, but it brought me to other questions.

So ill start here andill bring up all achievements in here.

I started generating a circle, dividing it in points, selecting 1 point on two to join them in an arc. but it came i wondered if we could delete intersecting geometry.

In 01.jpg join in here, i just deleted in rhino the segments i didnt wanted (for example)

How could it be done in grasshopper?

In 02.jpg i just simplified my issue with a rectangle and a circle. If the two overlap, is it possible to create a new line with largest segment as show in the image?

Thank you for your help and wish u all great developpements!

You can use Trim with Regions from the Intersect >> Region tab.

This has used circles instead of arcs and they are in slightly different positions but I guess you can adjust to suit.

Thank you

i started using this technique of trimming.

I was trying to use the created curve to build make surface so i can for example populate point inside of it. 

I could only make a surface out the initial curve but not the trimmed one.

Maybe someone has a way to to that.

I join the step two of the mandala construction.

Thank you
