CADBIMHub is a free library of CAD and BIM files for architectural, structural and MEP work — blocks, typical details, legends and installation drawings that engineers and draughtsmen can use directly in their own projects.
Who runs this site
CADBIMHub is run by Muhammad Faisal, an MEP engineer and fire protection draughtsman based in Riyadh, Saudi Arabia. My day-to-day work covers fire protection, HVAC and plumbing design and shop drawings for projects across the Gulf, working to NFPA standards, the Saudi Building Code and Saudi Civil Defence requirements. That is where the content on this site is strongest.
What makes these files different
Most CAD download sites publish a block and a one-line description. Every file here comes with notes written from site experience — what fails inspection, what is right on the drawing but wrong when built, and what the code actually requires. Where a drawing has an error, a missing unit or a detail that does not suit Gulf practice, the page says so.
Files are checked before publishing, but they are typical details and library blocks, not a design for your project. Please read the disclaimer before relying on any drawing.
