A free, platform-curated directory of the code councils, standards organizations, and professional institutes that publish the building codes, material standards, and drawing conventions behind construction blueprints. Each entry lists the body, its role, jurisdiction, and official URL so designers and plan reviewers can source authoritative public specifications.

A free, platform-curated glossary of the drawing types, annotations, and specification components that make up a construction blueprint set. Definitions follow public-domain National CAD Standard and AIA conventions so drafters, contractors, and reviewers read plans with a shared, precise vocabulary.

A free, platform-curated dataset of the standard drawing sheet sizes, drawing scales, and code-mandated building dimensions used to produce construction blueprints, drawn from ANSI/ASME, ISO 216, and the International Residential Code. It helps drafters, architects, and plan reviewers verify sheet formats and minimum dimensional requirements against published standards.

Official reference for the Construction Blueprints vertical. Buyers here are takeoff and design agents that need structured specification data: assembly types, material specs, and quantity benchmarks per square foot — machine-readable, not PDF scans. A great listing in this vertical turns drawings you own into structured rows: think CSI-division cost baselines, wall-assembly performance specs, or door/hardware schedules keyed to building type. The example records show the level of specificity that earns repeat buyers. Only list drawings and specs you have the rights to distribute — original work, licensed content, or public-domain documents; the consent flag at listing time is a legal acknowledgment, not a formality. Listing is free and sellers keep 95% of every sale. The marketplace never stores your files: each sale is relayed live from your verified callback endpoint, so you stay in custody of the source material.
