3D model association in PCB Design - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to link a 3D model file to a PCB footprint.

PCB Design

footprint.set3DModel('[1]')

Drag options to blanks, or click blank then click option'

Amodel.3d

Bmodel.stp

Cmodel.step

Dmodel.pcb

💡 Hint

Common Mistakes

Using incorrect file extensions like .pcb or .3d

Confusing .step with .stp

The standard 3D model file extension for PCB footprints is .stp.

2fill in blank

medium

Complete the code to assign the 3D model path to the footprint.

PCB Design

footprint.[1] = '/models/[2]'

Drag options to blanks, or click blank then click option'

Amodel_path

Bmodel_file

CmodelPath

DmodelLocation

💡 Hint

Common Mistakes

Using camelCase instead of snake_case

Using incorrect property names

The property to assign the 3D model file path is usually model_path.

3fill in blank

hard

Fix the error in the code to correctly associate the 3D model with the footprint.

PCB Design

footprint.attach3DModel([1])

Drag options to blanks, or click blank then click option'

Amodel.stp

Bmodel

C"model.stp"

D'model.stp'

💡 Hint

Common Mistakes

Passing the file name without quotes

Passing a variable that is undefined

The file name must be passed as a string literal with quotes.

4fill in blank

hard

Fill both blanks to create a dictionary mapping footprint names to their 3D model files.

PCB Design

model_map = {'[1]': '[2]'}

Drag options to blanks, or click blank then click option'

AR1

BC1

Cresistor.stp

Dcapacitor.stp

💡 Hint

Common Mistakes

Mixing footprint names and model files

Using wrong file extensions

The footprint 'R1' is associated with the resistor 3D model file 'resistor.stp'.

5fill in blank

hard

Fill all three blanks to define a function that associates a 3D model file to a footprint.

PCB Design

def associate_3d_model([1], [2]):
    [3].set3DModel([2])

Drag options to blanks, or click blank then click option'

Bmodel_file

Dmodel

💡 Hint

Common Mistakes

Using wrong parameter names

Not calling the method on the footprint object

The function takes a footprint and a model file, then sets the 3D model on the footprint.
