Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "For our initial shape, we will subtract a circle from a square using the difference operation."

A block of code is set as follows:

difference()
{
    translate([100,0])square(200, true);
    translate([200,0])circle(80);
}

Any command-line input or output is written as follows:

module_name(parameters)
{
	body_of_module
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "To do so, open OpenSCAD and click on the New button."
