Where to find CAD details and BIM objects
Where to look for CAD details and BIM objects, how to judge whether a file is current and usable, and what to confirm with the manufacturer before it goes into your drawings.
You can find CAD details and BIM objects on manufacturer websites, on product-content libraries, and from industry bodies, but you should treat every file as a starting point until its source, date and fit to your project are confirmed. This page lists where to look and how to check what you download.
Where to look
- The manufacturer. Most product pages have a downloads or technical area with DWG, DXF, RVT or IFC files next to the datasheet. This is the primary source and the best place to confirm currency.
- Product-content libraries. Several commercial and free libraries host objects from many manufacturers. They save search time. Check each file for a manufacturer name, a version and a date.
- Industry associations. Bodies such as CFSEI for cold-formed steel and AISC for structural steel publish technical resources. They are not product catalogues, but they help you understand what a detail should show.
- Your own design team. Architects and engineers often keep company libraries of details already used and reviewed. Ask before downloading anything new.
- Your supplier. A supplier or fabricator can often provide shop-drawing-level details specific to what it will actually deliver. See shop drawing.
CAD detail versus BIM object versus datasheet
These three are often confused. A CAD detail is a 2D drawing of a connection or assembly. A BIM object is a data-carrying model element. A datasheet is a document of properties and test results. Each answers a different question, and our comparison BIM object vs CAD detail vs product datasheet explains when you need which. Also see the glossary entries for BIM object and CAD detail.
A checklist before you accept a file
| Check | Why it matters |
|---|---|
| Manufacturer name and product code on the file | Generic or unlabelled files cannot be tied to a real product. |
| Version or issue date | Products and tested assemblies are revised; old files may show discontinued sizes. |
| Units and scale | Metric and imperial mix-ups are a common cause of errors in imported files. |
| Dimensions match the datasheet | Objects are sometimes simplified or rounded. |
| Properties embedded (material, fire or acoustic data) | If properties are blank, schedules from the model will be incomplete. |
| File opens cleanly in your software version | Newer files may not open in older software. |
| Licence or usage terms | Some libraries limit redistribution of files. |
What you still need from people
A downloaded detail does not tell you that the assembly is suitable for your loads, your climate or your local rules. That is the job of the designer and the engineer of record, with the local authority. Ask the manufacturer to state in writing which standards or tests the detail relates to, and file that statement with the drawing. If a detail shows fasteners or anchors, check the fastener documentation described in fasteners and connectors documentation.
Filing what you download
Save every file with its source URL, download date and the product code in the file name or a log. Keep the datasheet that was current on that day beside it. The folder structure in the materials document library guide works well for this, and how to organize construction product documentation covers the habits behind it.
When a supplier substitutes a product, the old detail stops applying. Record the change as described in how to record substitutions, and ask for the new object or detail before drawings are updated.
Questions people ask
Where is the safest place to get a BIM object?
The product manufacturer's own site is the primary source, since it controls the current version. Third-party libraries are convenient but can carry older files.
Is a CAD detail the same as a construction drawing for my project?
No. A manufacturer detail is generic. The designer must adapt it and the engineer of record must confirm it suits your project.
What file formats should I expect?
Commonly DWG or DXF for 2D details, and RVT or IFC for BIM objects. Check which your team's software uses.
How do I know a BIM object is accurate?
Compare its dimensions and properties with the current datasheet, and ask the manufacturer to confirm the object matches the shipped product.
