This is a flat (without history) import of (some of) the content from our markdown module. We've imported this without history because the repo contains our blog posts and showcases posts content prior to porting them to strapi. Since this contains many images, it would balloon the size of this repo to import the full history. Instead, please refer to the history of the (archived) markdown repo at: https://github.com/freesewing/markdown

| beamIntersectsCircle() |
array | false utils.beamIntersectsCircle(
Point center,
float radius,
Point point1,
Point point1,
string sort = 'x'
)
Finds the intersection between an endless line through points point1 and point2
and a circle with its center at point center and a radius of radius mm.
The 5th and last parameter controls the sorting of the found intersections. This will (almost) always return 2 intersections, and you can choose how they are ordered in the returned array:
Set sort to:
x: The point with the lowest X-coordinate will go first (left to right)y: The point with the lowest Y-coordinate will go first (top to bottom)
