Plain-English answer

Use a factory paper wrapper template or a layout software app to generate the complex wrapping profile curve cut lines for the target pipe diameter.

Wrap the template flat around the perimeter of the straight round pipe section, trace the profile line cleanly with a soapstone marker, then use your aviation snips or plasma cutter to follow the line precisely.

Field checklist

Ask Foreman

Hey boss, I’m checking field math & measuring: How do I lay out a round lateral (wye) branch using a template? I found the likely issue and want to verify the next step before I lock it in. Do you want me to adjust it now or check the drawing/detail first?

Verify before acting

Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
