simple way to make rounded 3d blocks and rectangles in open scad

This appears to be a 3D modeling script written in OpenSCAD. Here's a breakdown of the code: **Modules** The first section defines several modules that will be used throughout the script. These are functions that encapsulate specific pieces of functionality. * `cube(size=vector([1,2,3]), center=true);` - Creates a cube with dimensions 1x2x3. * `sphere(d=bevel, $fn=bevel\*detail);` - Creates a sphere with diameter `bevel`. * `cylinder(d=bevel, h=Xw-bevel, center=true);` - Creates a cylinder with diameter `bevel` and height `Xw - bevel`. **Main Script** The main script is defined after the modules. It appears to be creating a rounded 3D block. Here's what it does: 1. It creates four spheres at each corner of the block, using the `sphere()` module. 2. It creates six cylinders around the edges of the block, using the `cylinder()` module. 3. It creates eight cylinders in the middle of the block, also using the `cylinder()` module. **Arguments** The script takes several arguments: * `Xw`, `Xl`, and `Xh` are vectors representing the width, length, and height of the block. * `bevel` is a scalar value that controls the radius of the rounded edges. * `detail` is an integer value that affects the resolution of the model. **Notes** * The script uses OpenSCAD's built-in modules for creating shapes (e.g. `cube()`, `sphere()`). * The script uses OpenSCAD's vector math to perform calculations and transformations (e.g. `[Xw*0.5-bevel*0.5]`). * The script relies on the `bevel` value to control the rounded edges, which suggests that this is a design element intended to be adjusted by the user. **Example Use Case** To use this script, simply call it with the desired arguments: ```scad rounded_3d_block(Xw=[10, 20, 30], Xl=15, Xh=18, bevel=3); ``` This would create a rounded 3D block with width 10x20x30, length 15, height 18, and rounded edges of radius 3.
