What it is.

Rough openings from the maker's allowances, flashing held to the maker's steps, and egress checked against your code's numbers. Use when an installer needs rough openings, a flashing check or an egress check. Not for skipping a permit, or sizing structure itself. For headers and framing → THE FRAMER

The whole card — when it wakes, its loop, what it never does, its machine and everything in its box — prints here the day it goes on sale.

Take it.

Nº 1691 —Liquid error (snippets/job-room line 44): comparison of String with 0 failed

Sold as is under the term printed. A card instructs an AI you operate; results depend on your model, your files and your judgement. Not medical, legal, tax or financial advice, never the person’s boss, and not a licence to practise. The terms →

ONE PAYMENT · NOTHING RENEWS ITSELF

OFFLINE · ONE LICENCE · PUNCH-CHECKABLE · THE STANDARD

One payment. The file is yours to keep and keeps working at its edition; new editions issued in the year after you buy reach you by email as replacement files. Tax is added at checkout where it applies. Nothing auto-renews.

One email when it is on sale, from the studio; nothing else, ever.
