This is a really simple trig problem, but my brain is stuck on it. I'm designing an object in OpenSCAD (3D Drafting), and in order to 'draw' the object, I need to specify a set of points [x,y]. Together, the points makes a closed polygon. Ex: Square is represented by [0,0],[10,0],[10,10],[0,10]
I'm fine with 90 degree corners, but when my object has angles, I don't know how to specify the correct coordinates, and my objects come out skewed. Basically, given a curved object, how do I determine a set of coordinates?
Example: Trying to determine the x-coordinates for an angled object:
How would I find those two question mark coordinates?
