The -d and -m options only make sense together. Start - Settings - Control Panel - System - Advanced tab - Environment Variables - System Variables, select Path, then click Edit. If it closes without processing, check to set the PATH by adding openscad directory to: bat file with text:įOR %%f in (*.scad) DO openscad -o "%%~nf.stl" "%%f" If OpenSCAD is given the option -m make, it starts make file the first time it tries to access a missing file.Įxample to convert all the. In a complex build process, some missing files required by an OpenSCAD file can be generated if they are defined in a Makefile. Pb = new ProcessBuilder("/usr/bin/openscad", For example a Java application might start a process like so: Note that this sort of double-escaping isn't necessary when executing OpenSCAD from another process that isn't using a shell, because each argument is passed separately. Openscad -o my_model_production.stl -D "quality=\"production\"" my_model.scad Or you may need to escape the inner quotes instead: o my_model_production.stl -D "quality=""production""" my_model.scad Openscad -o my_model_production.stl -D 'quality="production"' my_model.scad For example to assign a string production to a quality parameter one has to ensure the " characters OpenSCAD expects aren't stripped by the shell. 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. 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 | \ check-parameter-ranges arg =true/false, configure the parameter range check check-parameters arg =true/false, configure the parameter check for q quiet mode (don't print anything *except* m arg make_cmd -runs make_cmd file if file is missing d arg deps_file -generate a dependency file for make Solarized | Tomorrow | Tomorrow 2 | Tomorrow Starnight | BeforeDawn | Nature | DeepOcean | colorscheme arg =colorscheme: *Cornfield | Metallic | Sunset | csglimit arg =n -stop rendering at n CSG elements when projection arg =(o)rtho or (p)erspective when exporting png view arg =view options: axes | crosshairs | edges | render arg for full geometry evaluation when exporting png imgsize arg =width,height of exported png autocenter adjust camera to look at object's center camera arg camera parameters when exporting png: info print information about the build process Off, amf, 3mf, csg, dxf, svg, png, echo, ast, GUI, the file extension specifies the type: stl, o arg output specified file instead of running the OpenSCAD can not only be used as a GUI, but also handles command line arguments.
