box API for SCAD

説明

Introduction This thing is just a SCAD script that provide an API to manipulate parts of a models by placing them relative to each other. When writing SCAD models i found out that the result scripts are not readable. Even when i read them myself many days later i don't understand what i wrote and why i wrote them this way. The main reason is that i use a lot of constant values computed or measured on parts in real life and even with comments in code this is hard to read. Furthermore when i want to make modifications i don't know where to apply them in code. This API simplify all my designs by allowing me to place parts relatives to each other. This thing is designed using this library: http://www.thingiverse.com/thing:2005142 How it works Boxes basics Each elementary part of the model (cube, cylinder etc...) can be bounded by a box that you create using the api boxCreate(). Boxes faces are always aligned with x,y,z axis. The boxCreate api just take the size of the box on [x,y,z] before any rotation: boundingBox = boxCreate ( [1, 1, 1] ); The object returned is an array on which we can get some computed values using indexes (which are all listed at the beginning or the file box.scad). For instance these indexes returns the size elements of the box. When the box is first created these are just the values we gave: boundingBox[idx] boundingBox[idy] boundingBox[idz] The following indexes returns the position values on x,y,z of the center of the box. The center of the box is the…
