Command: HEADERPRO

Designed for full-size, inch-based drawings using two parallel straight LINE wall edges. Written using classic AutoLISP and DCL for AutoCAD 2002-era environments; runtime compatibility requires testing in your installation.

Please note: This is a drafting tool. It does not calculate structural header sizes or required bearing.
