Create your own LEGO FeatureScript

Goal: Write your own FeatureScript which automatically generates LEGO bricks.

Getting Started:

While most of the steps for creating your own brick FeatureScript can be found as comments within the code in the feature studio of this Onshape document*, here are some hints to get you started:

*The code in the "My Script" tab was written using the public brick correct code as a reference.

The Basics of FeatureScript:

Start with creating a new feature studio.

Create a new feature and add input parameters. These will determine the size and type of brick you are creating.

Create a sketch and add sketch entities.

Extrude the sketch

Advanced Tips & Tricks:

Using Vector Math to Create Rectangles

In this example "definition.myRows" and "definition.myColumns" are variables representing the number of rows and columns input by the user. Create an inner and outer rectangle using the skRectangle function, and determine the location of the corners of each rectangle using the input variables. Remember that each stud of a LEGO brick is 8 mm apart.

Creating a For loop

Hint: Use nested for loops to create m rows and n columns of studs, where m and n are the variables you defined in the input parameters. (For the example code the variables are definition.myRows and definition.myColumns).

Using the ~ Operator

If you try to create multiple sketch entities using a for loop, FeatureScript will return an error because all of the entities you created have the same name. If you create an integer variable that increments every time you run he for loop, (lets call it "intCount" in this example), you can use the ~ operator to give each entity a unique name.
