OpenSCAD is a free script based application for creating solid 3D CAD objects.
Install OpenSCAD in your computer
It has a specific description language which specifies geometric primitives and defines how they are modified to render a 3D model. No one likes manuals, but you have to read the manual sometimes.
Script based CAD software like OpenSCAD has a number of advantages over traditional and more intuitive click and drag software.
Name a few advantages of script based CAD software. Can you imagine any disadvantage also?
It also helps you develop some personal skills like abstraction, rigor and spatial vision. In fact, when you master OpenSCAD you will see like this:
In all code, commenting is very important. OpenSCAD uses C style comments.
// This is a single line comment in C and also OpenSCAD
/*
And this is a multiple
line comment in C and
also in OpenSCAD
*/Not only comment every step you do (so others can learn from you) but also include a header in every file with the following information:
- filename
- short description
- your name (author)
- date
- license and credits
You will greatly appreciate that info when you or others open the file later in the future.
The Hello-world of OpenSCAD is a cube.
cube(size=[x,y,x]); creates a cube with one corner on the origin and x,y,z dimensions like cube([10,20,30]);
Why did the above code work if
size=was omitted? Create a 15x15x15 cube centered in the origin.
Rotations are about an axis using the right hand rule.
TODO the logic, loops, runtime, compile time variables "The variable retains its last assigned value at compile time, in line with Functional programming languages"
