The right hand sides can be arbitrary OpenSCAD expressions, including mathematical operations and strings.īe aware that your shell (bash, cmd, etc.) parses the arguments before passing them to openscad, therefore you need to properly quote or escape arguments with special characters like spaces or quotation marks. Without the first line, val would be undefined. Val=param1 // param1 passed via -D on cmd-line If you want to assign the -D variable to another variable, the -D variable MUST be initialized in the main. Unlike normal OpenSCAD assignments, these assignments don't define variables, but constants, which cannot be changed inside the program, and can thus be used to overwrite values defined in the program at export time. Each occurrence of -D must be followed by an assignment. In order to pre-define variables, use the -D option. This is done by adding '-render' as an option.
OPENSCAD ECHO FULL
For some situations it may be desirable to output the full render, with CGAL. png output uses Preview mode (f5) with OpenCSG. png dimensions and -projection chooses orthogonal or perspective, as in the GUI.īy default, cmdline. The second camera type is a 'vector' camera, with an 'eye' camera location vector and a 'lookat' center vector. The first camera type is a 'gimbal' camera that uses Euler angles, translation, and a camera distance, like OpenSCAD's GUI viewport display at the bottom of the OpenSCAD window. There are two types of cameras available for the generation of images. Multiple output files are not supported, so using this option you cannot also obtain the model that would have normally been generated.įor 2013.05+, the option to output a. echo causes openscad to produce a text file containing error messages and the output of all echo() calls in filename as they would appear in the console window visible in the GUI. If the option -d is given in addition to an export command, all files accessed while building the mesh are written in the argument of -d in the syntax of a Makefile.įor at least 2015.03-2+, specifying the extension. Some versions use -s/-d/-o to determine the output file format instead check with "openscad -help". When called with the -o option, OpenSCAD does not start the GUI, but executes the given file and exports to the output_file in a format depending on the extension (. The usage on OpenSCAD version 2011.09.30 (now deprecated) was: [ -camera=translatex,y,z,rotx,y,z,dist | \ Solarized | Tomorrow | Tomorrow 2 | Tomorrow

That means there's no nice, readable way to define the vector, you just have to comment it.OpenSCAD can not only be used as a GUI, but also handles command line arguments. So far all I can think of is using vectors and using variables to map indexes into the vector to human readable names.
OPENSCAD ECHO HOW TO
Does openscad have any language primitive for string-keyed associative arrays (a.k.a hash maps, a.k.a dictionaries)? Or is there any convention for how to emulate associative arrays?
