  • 在[Edit]菜单里,选择[Preferences]再打开[Features]选项卡,选中[Customizer],最后关闭此窗口。
  • 在View菜单里,您将看到一个[Hide customizer]选项,将其反选。


  • 仅支持主文件里所计算的变量。主文件里包括的文件并不在支持的范围内。
  • 只计算主文件里顶层的变量,即,为了让它们在定制器中可见,就必须将它们声明在任意函数与模块之前。
  • 如果您希望令某些变量在不出现在定制器中,至少将其置于第一个函数或模块的定义之后即可。

Creating Tabs[编辑]

Parameters can be grouped into tabs. This feature will allows related parameters to be associated into groups. The syntax is very similar the Thingiverse rules for tabs. To create a tab, use a multi-line block comment like this:

/* [Tab Name] */


/* [Tab] [Name] */

Three tabs names have a special functionality;


Parameters in the Global tab will always be shown on every tab no matter which tab is selected. No tab will be displayed for “Global” parameters, they will always be shown in all the tabs.


Parameters in the Hidden tab (with first letter uppercase) will never be displayed. Not even the tab will be shown. This prevents global variables that have not been parameterized for the Thingiverse or OpenSCAD Customizer from showing up in the Customizer interface or widget. Included for compatibility with Thingiverse. You can have multiples segments under the Hidden group. see also #hidden_parameters


Parameters that are not under any tab will be displayed under a tab named “parameters”. In Thingiverse, these parameters are listed with no tab.

openscad --enable=customizer -o model-2.stl -p parameters.json -P model-2 model.scad
openscad --enable=customizer -o <output-file> -p <parameteric-file (JSON File) > -P <NameOfSet> <input-file SCAD file >
  • -p is used to give input JSON file in which parameters are saved.
  • -P is used to give the name of the set of the parameters written in JSON file.

And JSON file is written in the following format:

        "FirstSet": {
            "Labeled_values": "13",
            "Numbers": "18",
            "Spinbox": "35",
            "Vector": "[2, 34, 45, 12, 23, 56]",
            "slider": "2",
            "stepSlider": "12",
            "string": "he"
        "SecondSet": {
            "Labeled_values": "10",
            "Numbers": "8",
            "Spinbox": "5",
            "Vector": "[12, 34, 45, 12, 23, 56]",
            "slider": "12",
            "stepSlider": "2",
            "string": "hello"
    "fileFormatVersion": "1"
              "set-name ":{
                         "parameter-name " :"value ",
                         "parameter-name " :"value "
             "set-name ":{
                         "parameter-name " :"value ",
                         "parameter-name " :"value "
    "fileFormatVersion": "1"


Through GUI you can easily apply and save Parameter in JSON file using Present section in Customizer explained below.

In customizer, the first line of options is as follows:

  1. Automatic Preview : If checked preview of model will be automatically updated when you change any parameter in Customizer else you need to click preview button or press F5 after you update parameter in customizer.
  2. Show Details:
    1. Show Details: If chosen, the description for the parameter will be shown below the parameter name.
    2. Inline Details: If chosen, the description for the parameter will be shown right next to the parameter name. Long descriptions get clipped, speak not fully shown. This option is a compromise between vertical space usage and still having part of the description.
    3. Hide Details: It will not be displayed but you still can view the description by hovering the cursor over the input widget.
  3. Reset button which when clicked resets the values of all input widgets for the parameter to the default provided in SCAD file.

Next comes Preset section: It consist of four buttons:

combo Box
It is used to select the set of parameters to be used
+ button
add new set of the parameters
– button
It is used to delete the set selected in combo Box.
save preset button
save/overwrite the current preset

and finally below Preset Section is the Place where you can play with the parameters.

You can also refer to two examples that are Part of OpenSCAD to learn more:

  1. Parametric/sign.scad
  2. Parametric/candlStand.scad

manually create datasets[编辑]

You can manually create a dataset by modifying the JSON file according above format and defining your own variables. When a dataset is loaded, only the parameters defined in the dataset are modified, other parameters are NOT set to defaults. This allow one to create partial datasets which are only modifiers, not complete dataset.

hidden parameters[编辑]

Variables belonging to the hidden group are stored in the JSON file, but are NOT retrieved from the JSON file.

Meaning: If a variable is moved from the hidden group to an other group, it also becomes applicable. This allows a designer to use the hidden group for reserved variables, that become customizable (and assigend with a different default) in a future version, without breaking existing preset.

A hidden variable can also be used as a "last saved with" indicator, that can be read by manually viewing the JSON file.

The idea is, that the customizer only modifies variables that the user can see and control from the customizer UI.

Tips and Tricks[编辑]

Set Range and Stepping[编辑]

The customizer tries to guess an appropriate range and stepping. However it can/will be inconsistent, as the customizer does not know your design intent. For example, the customizer also treats numbers like 0.0, 1.0, 2.0 etc. as integers. The customizer also does not know whether or not negative numbers make sense. It is therefor highly recommended to always supply range and step as comments. Keep in mind, that if in doubt, the user can always modify the scad file.

Do not hesitate to limit the range. For instance, in the design of a smart phone holder, limit the size to reasonable smart phone sizes. If someone wants to use your smart phone holder as a tablet holder, he always can directly edit the SCAD file itself. This act also makes the user aware, that the design was not meant as a tablet holder and that he or she might need for example to modify the support structure

Scroll Wheel[编辑]

The buttons on the spinboxes are small, but you can use the scroll wheel on your mouse to change the value comfortably. First, click on the spin box to focus the spin box.


color =[编辑]

cubeColor = [1,0.5,0]; //[0:0.1:1]
sphereColor = "blue"; // [red, green, blue]
