Auto-generates piping diagrams with dimensions and annotations
Provides a bill of materials with links to purchase
Includes local plumbing code lookup by jurisdiction

Target Users: Licensed plumbers and apprentices in residential and commercial plumbing, especially those handling ice machine and appliance installations.
