3D visualization for clearance check in PCB Design - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to load the 3D model for clearance checking.

PCB Design

model = load_3d_model('[1]')

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

Apcb_model.stp

Bclearance_check.csv

Cdesign_rules.txt

💡 Hint

Common Mistakes

Choosing a non-3D file format like CSV or XML.

The 3D model file (usually with .stp extension) is loaded to visualize the PCB for clearance checks.

2fill in blank

medium

Complete the code to set the minimum clearance distance for the check.

PCB Design

set_clearance_distance([1])

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

B0.5

C50

💡 Hint

Common Mistakes

Setting clearance too large, causing false errors.

Clearance distances are usually small, like 0.5 mm, to ensure components don't touch.

3fill in blank

hard

Fix the error in the code to correctly highlight clearance violations.

PCB Design

highlight_violations(color=[1])

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

A(255,0,0)

Bred

C255,0,0

D"red"

💡 Hint

Common Mistakes

Passing color as tuple or unquoted string.

The color parameter expects a string with the color name in quotes, like "red".

4fill in blank

hard

Fill both blanks to filter components and check clearance only on them.

PCB Design

components = get_components(filter_by=[1], clearance=[2])

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

A"power"

B"signal"

C0.5

D5

💡 Hint

Common Mistakes

Mixing filter and clearance values.

Filtering by "power" components and setting clearance to 0.5 mm focuses the check on critical parts.

5fill in blank

hard

Fill all three blanks to generate a report with clearance issues and save it.

PCB Design

report = generate_report(components=[1], threshold=[2], format=[3])
save_report(report, 'clearance_issues.[3]')

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

B0.5

C"pdf"

D"csv"

💡 Hint

Common Mistakes

Mismatching report format and file extension.

The report is generated for the components list with a 0.5 mm threshold and saved as a CSV file for easy viewing.
