| | 4 | roundedCube() v1.0.3 by robert@cosmicrealms.com from https://github.com/Sembiance/openscad-modules |
| | 5 | Allows you to round any edge of a cube |
| | 6 | |
| | 7 | Usage |
| | 8 | ===== |
| | 9 | Prototype: roundedCube(dim, r, x, y, z, xcorners, ycorners, zcorners, $fn) |
| | 10 | Arguments: |
| | 11 | - dim = Array of x,y,z numbers representing cube size |
| | 12 | - r = Radius of corners. Default: 1 |
| | 13 | - x = Round the corners along the X axis of the cube. Default: false |
| | 14 | - y = Round the corners along the Y axis of the cube. Default: false |
| | 15 | - z = Round the corners along the Z axis of the cube. Default: true |
| | 16 | - xcorners = Array of 4 booleans, one for each X side of the cube, if true then round that side. Default: [true, true, true, true] |
| | 17 | - ycorners = Array of 4 booleans, one for each Y side of the cube, if true then round that side. Default: [true, true, true, true] |
| | 18 | - zcorners = Array of 4 booleans, one for each Z side of the cube, if true then round that side. Default: [true, true, true, true] |
| | 19 | - rx = Radius of the x corners. Default: [r, r, r, r] |
| | 20 | - ry = Radius of the y corners. Default: [r, r, r, r] |
| | 21 | - rz = Radius of the z corners. Default: [r, r, r, r] |
| | 22 | - center = Whether to render the cube centered or not. Default: false |
| | 23 | - $fn = How smooth you want the rounding to be. Default: 128 |
| | 24 | |
| | 25 | Change Log |
| | 26 | ========== |
| | 27 | 2018-08-21: v1.0.3 - Added ability to set the radius of each corner individually with vectors: rx, ry, rz |
| | 28 | 2017-05-15: v1.0.2 - Fixed bugs relating to rounding corners on the X axis |
| | 29 | 2017-04-22: v1.0.1 - Added center option |
| | 30 | 2017-01-04: v1.0.0 - Initial Release |
| | 31 | |
| | 32 | Thanks to Sergio Vilches for the initial code inspiration |
