![]() This allows to produce files that can be used for sheet metal cutting, machining and renders – while allowing for complex designs without creating a mess. I’ve used OpenSCAD 3 to produce a few things that were sent to be manufactured this article shows how I adapt its output capabilities and how I approach a design. 1ĭespite being actively developed, broadly used and powerful 2 there are many shortcomings which make it difficult or sometimes impossible to use outside of 3D printing. It’s popular within the 3D-printing community due to its ability to produce STL files. As it’s script-based, it’s fantastic for parametric design and the files can be version controlled just like a software project. -P is used to give the name of the set of the parameters written in JSON file.OpenSCAD is an open-source CSG based script-only CAD package.-p is used to give input JSON file in which parameters are saved.JSON parameter values can be then reused through the command line.Ĭmdline openscad -enable=customizer -o model-2.stl -p parameters.json -P model-2 model.scad This feature gives the user the ability to save the values of all parameters. Text box for vector with less than or equal to 4 elements ![]() Text box for vector with more than 4 elements In Thingiverse, these parameters are listed with no tab. Parameters that are not under any tab are displayed under a tab named “parameters”. You can have multiples segments under the Hidden group. Included for compatibility with Thingiverse. This prevents global variables that have not been parameterized for the Thingiverse or OpenSCAD Customizer from showing up in the Customizer interface or widget. Parameters in the Hidden tab (with first letter uppercase) are never displayed. No tab is shown for Global parameters they appear in all the tabs. Parameters in the Global tab are always shown on every tab no matter which tab is selected. Three tabs names have a special functionality To create a tab, use a multi-line block comment like this: The syntax is very similar the Thingiverse rules for tabs. This feature allows related parameters to be associated into groups. Directly editable (non-spinbox) numeric values:.Some desirable customization constraints are not supported in 2019.05. Variable name = defaultValue // possible valuesįollowing is the syntax for how to define different types of widgets in the form:Įxperimental-build configurator example 6 //Spin box box for vector with less than or equal to 4 elements Syntax support for generation of the customization form // variable description Only literals are available as parameters. Module does_not_stop_customizer () echo("Fails in 2019.05") Module _Customizer_Limit_ () // This actually works For example, this will stop the customizer If you want to hide some variables from the customizer, they must be put on or after the first line that declares a module with a compound body.Only the variables that are on the top of the main file are evaluated, that is, they must be declared before the first line with a module declaration in order to appear in the customizer (read the next bullet point).Files from includes and use are not considered. Only variables in the main file are evaluated.In the Window menu, the option called must be unselected to display the customizer. Sets of parameter values can also be saved, which effectively saves a variant of a particular model. Programmers can create templates for a given model, and customize these further to adapt to different needs / users. With this feature one does not need to edit the code to change the values of the parameters / variables. The Customizer feature provides a graphic user interface for editing model parameters. 1.6 Saving Parameters value in JSON file.1.3 Syntax support for generation of the customization form.
