Different roles need different tools. Architects, designers, and specifiers each need specific product files - there’s no single format that fits all.
A good library gives you options. We offer every major file type - line drawings, DWG, STEP, Revit - so you can get what you need and keep moving.
Here’s a quick guide to what each file type does and when to use it:
All major file types
No one format fits every job. CAD leads need DWGs, designers need 3D models, others just need a spec sheet. That’s why we offer all major file types - so every role can get exactly what they need and keep the project moving.
An architect might need precise 2D DWG files to ensure a furniture layout complies with building regulations.
An interior designer may require 3D models to create photorealistic client renderings.
A specifier or procurement manager might only need a simple PDF tear sheet with product codes and dimensions.
A full set of file types means less friction. Each role gets the right tool - no delays, no workarounds, just faster specification and a smoother project.
A Practical Guide to Product File Formats
Here’s a no-nonsense guide to each product file - what it does, when to use it, and how to choose fast.
Line Drawings (PDF, JPEG)
Line drawings are simple 2D views with key dimensions - provided as PDFs or JPEGs for easy sharing and printing.
When to use them:
Early conceptual stages: Perfect for dropping into presentations, mood boards, or initial sketches to communicate design intent without technical overhead.
Quick reference: Ideal for specifiers, clients, or project managers who need to quickly verify a product's overall size and shape without opening specialised software.
Print documentation: Easy to print and include in physical project binders or share as simple attachments in an email.
Line drawings are quick, clear, and universal. Open, print, or share - no technical know-how needed.
2D DWG Files
2D DWG files are accurate, vector drawings for AutoCAD. They show footprints and layouts - useful for technical, detailed planning.
When to use them:
Space planning: 2D DWG files are essential for creating accurate floor plans. Architects and designers use them to test layouts, check clearances, and ensure the furniture fits within the designated space.
Technical documentation: These files are used to create detailed construction and installation drawings, providing contractors with the exact information they need.
Coordination: They allow designers to overlay furniture plans with other building systems, like electrical and HVAC, to prevent on-site conflicts.
DWG files set the standard for 2D precision - if accuracy matters, use DWG.
3D STEP Files
3D STEP files are universal models - quick to import, reliable in any major CAD software. Use them for 3D work, whatever your platform.
When to use them:
Visualisation and rendering: Interior designers and visualisation artists import 3D STEP files into their software to create photorealistic renderings, giving clients a clear picture of the finished space.
Customisation: A 3D model allows a designer to check how a product looks from all angles and to test different material finishes before making a final decision.
Complex spatial analysis: In tight or unusually shaped spaces, a 3D model can help identify potential clashes or ergonomic issues that might be missed in a 2D plan.
STEP files are universal - use them in any major CAD platform for fast, reliable 3D import and workflow flexibility.
Revit Files (.RFA)
Revit files (.RFA) are 3D BIM models with built-in data - dimensions, materials, and specs - ready for direct use in Revit.
When to use them:
BIM workflows: Revit is central to BIM, a process where a single, intelligent model is used by the entire project team. Placing Revit families into the master model ensures seamless coordination.
Data-rich scheduling: The data within a Revit file - such as manufacturer, model number, materials, and even sustainability information - can be automatically pulled into project schedules, reducing manual data entry and errors.
Clash detection: In a BIM model, Revit can automatically detect if a piece of furniture conflicts with a structural beam, a pipe, or an electrical conduit, saving time and money on site.
Revit files slot straight into BIM projects - built-in data, fast coordination, no fuss.
Making Specification Move Faster
A complete, well-organised CAD library means you get the right file fast - no delays, no conversions, no wasted time.
At Workbench, our download library is clear, organised, and built for real work. All major file types, ready to download. No chasing files, just fast access and support when you need it.
By providing clear, well-organised, and accessible CAD data files, we help you focus on what you do best: designing exceptional spaces.
