box API for SCAD

thingiverse

The code you provided is written in SCAD (Simplified Computer-Aided Design), which is a programming language used for creating 3D models. Here's a breakdown of what the `boxRenderConeBottom` function does: 1. It takes three arguments: `bbox`, `sd`, and `fn`. * `bbox` is the bounding box of the object, represented as an array `[x, y, z]`. * `sd` is the small diameter of the cone. * `fn` is the number of facets to use when rendering the cone (default value is 180). 2. It creates a cylinder with a diameter equal to the minimum value of the borders of the cylinder's base. 3. It creates a cone with a large diameter equal to the minimum value of the borders of the cone's base and a small diameter `sd`. 4. The resulting object is bounded by the global box. The function uses various SCAD functions, such as `boxCreate`, `boxMoveTo`, `boxRotate`, and `boxRenderCylinderX`. Here are some examples of how to use this function: Example 1: ```scad mainBoxSize = [8.4, 9.1, 10.5]; cylinderXSize = [8.5, 1.2, 1.2]; cylinderYSize = [0.8, 5.4, 0.8]; mainBox = boxCreate(mainBoxSize); cylinderX = boxMoveLeftTo(boxCreate(cylinderXSize), mainBox[ixmax]); cylinderY = boxMoveFrontTo( boxMoveBottomTo( boxMoveLeftTo( boxRotate( boxCreate(cylinderYSize) , cylinderYRotation ) , cylinderX[ix] ) , cylinderX[iy] ) , cylinderX[iz] ); color("White") boxRenderCube(mainBox); color("Red") boxRenderCylinderX(cylinderX); color("Green") boxRenderConeBack(cylinderY); ``` Example 2: ```scad test = boxRotate( boxMoveTo( boxRotate( boxCreate([2, 10, 20]) , [110,30,20] ) , [10, 20, 30] ) , [10,0,0] ); testResized = boxResize(test, 1); plane = boxCreate([0.0001, 10, 10]); difference() { boxRenderCube(testResized); boxRenderCube(boxResizeX(test, 1)); boxRenderCube(boxResizeY(test, 1)); boxRenderCube(boxResizeZ(test, 1)); } boxRenderCylinderX(boxResizeX(test, 1), $fn=100); boxRenderCylinderY(boxResizeY(test, 1), $fn=100); boxRenderCylinderZ(boxResizeZ(test, 1), $fn=100); #translate([testResized[ixmax], testResized[iy], testResized[iz]]) rotate([0,0,0]) boxRenderCube(plane); #translate([testResized[ixmin], testResized[iy], testResized[iz]]) rotate([0,0,0]) boxRenderCube(plane); #translate([testResized[ix], testResized[iymax], testResized[iz]]) rotate([0,0,90]) boxRenderCube(plane); #translate([testResized[ix], testResized[iymin], testResized[iz]]) rotate([0,0,90]) boxRenderCube(plane); #translate([testResized[ix], testResized[iy], testResized[izmax]]) rotate([0,90,0]) boxRenderCube(plane); #translate([testResized[ix], testResized[iy], testResized[izmin]]) rotate([0,90,0]) boxRenderCube(plane); ``` Note that the `boxRenderConeBottom` function is not explicitly defined in your code snippet. It seems to be a custom function created elsewhere in the SCAD file.
