Description
Expected Behavior
An object with area, bounds and volume is located at the position pointed by translate().
Actual Behavior
In some case, an object's area is disappeared by translate() with certain values.
Steps to Reproduce the Problem
The problem can be reproduced by this script.
// V2
const { cuboid, cylinder } = require('@jscad/modeling').primitives
const { translateX, translateY } = require('@jscad/modeling').transforms
const { subtract } = require('@jscad/modeling').booleans
const { measureArea, measureBounds, measureVolume } = require('@jscad/modeling').measurements
const main = () => {
const plateZ=1;
const len=100;
const holeRad=3;
const holeDis=9.5;
let ret;
let binder=translateX([len/2],
cuboid({size: [len, holeDis, plateZ]}));
for (i=holeDis/2; i <=len-holeDis/2; i+=holeDis ) { // punching loose-leaf notebook's holes
binder=subtract(binder, translateX([i],
cylinder({ startRadius: holeRad, endRadius: holeRad, height: plateZ })));
}
for (y=0; y<=3; y+=0.1) {
ret=translateY([y], binder);
console.log(y pos: ${y}, Area: ${measureArea(ret)}, Bounds: ${measureBounds(ret)}, Volume: ${measureVolume(ret)}\n)
}
return [ ret ]
}
module.exports = { main }
