Numbers are the most important type of value in OpenSCAD, and they are written in the familiar decimal notation used in other languages. Values can be stored in variables, passed as function arguments, and returned as function results. Values and data types Ī value in OpenSCAD is either a Number (like 42), a Boolean (like true), a String (like "foo"), a Range (like ), a Vector (like ), or the Undefined value (undef). Myvar = 10 // The rest of the line is a comment Comments are not evaluated by the compiler, and should not be used to describe self-evident code. Operator() operator() Ĭomments are a way of leaving notes within the script, or code, (either to yourself or to future programmers) describing how the code works, or what it does. This script is a free format list of action statements. OpenSCAD is a 2D/ 3D and solid modeling program which is based on a Functional programming language used to create models that are previewed on the screen, and rendered into 3D mesh which allows the model to be exported in a variety of 2D/3D file formats.Ī script in the OpenSCAD language is used to create 2D or 3D models. The text in its current form is incomplete.

The software will show the object as half transparent. ) in front of the command gives you this overview. When dividing geometric objects, it can be important to maintain an overview of which portion comes from which object. Is concluded with a character, this is not an error but the transformation does not produce output. For instance, if the transformation translate() It becomes more difficult to locate semicolons that are syntactically correct but logically false. The actual error is therefore to be found in the line that occurs before the program is interrupted. You will notice that a semicolon is missing when the program stumbles when switching to a succeeding command. Error messages that appear during script compilation appear in the console. This is a complete list of commands recognized by the software. The most important document for OpenSCAD is found in Help | Cheat_sheet The earthquakes on the surface are represented by the color green, and the deep earthquakes can be recognized by the color red. To the southwest, there are the Pacific and Australian plates that collide against one another. The text is not readable in the reproduction. The small black sphere in the graphic represents the city of Honolulu in Hawaii. As a result, you should construct these in the form of 3D objects from extruded slices of circles. OpenSCAD does not have one-dimensional lines without filling. The most complex task is building the grid. The function accepts one vector and returns the computed vector. The number of elements is given by the len()įrom the length, width, and depth of the spherical coordinates. Coordinates and names are found in the plock The code used for the example uses the coordinates of several cities for purposes of orientation. The coordinates and strength of the earthquakes are found in two arrays in the eq03.scadįile. Figure 8: The program is suitable for infographics as shown by the example involving the distribution of earthquakes of at least magnitude 5.
