AI-Assisted Detailing vs Real Fabrication Detailing
In recent years, “AI-assisted detailing” has been promoted as a way to automate drawing production for steelwork fabrication. While these tools can improve drafting speed, they often miss the fundamental requirement of fabrication: delivering clear, practical, and buildable information.
AI-assisted detailing typically focuses on:
- Automatically placing dimensions
- Suggesting annotations
- Increasing drawing completeness
However, more information does not necessarily result in better drawings.
🧠The Reality of Steel Fabrication
In many fabrication workshops, steel is still cut and prepared using:
- Oxy cutting
- Angle grinders
- Manual fit-up processes
In these environments, overly detailed drawings—such as those filled with X and Y coordinate systems or excessive dimensions—can create confusion rather than clarity.
What fabricators actually need is:
- Clear cut lengths
- Simple offsets and references
- Practical, easy-to-read drawings aligned with how the work is performed
⚙️ The Role of Rule-Based Detailing
Well-developed rule-based detailing systems, such as those used in Tekla Structures or customised CAD workflows, embed fabrication knowledge directly into the drawing process.
These systems:
- Apply predefined connection and detailing standards
- Produce consistent, fabrication-ready outputs
- Reflect workshop practices and capabilities
When properly configured, rule-based detailing removes the need for AI to “guess” what should be included in a drawing.
👷 Experience Still Matters
Detailers with decades of experience understand:
- What information is critical
- What can be omitted
- How drawings are interpreted on the workshop floor
This level of judgement cannot currently be replicated by AI.
🧠Our Approach
At Hamilton By Design, we focus on delivering engineering outcomes, not just automated drawings.
Our process:
- Starts with accurate, real-world data (including LiDAR where required)
- Applies structured, rule-based detailing aligned with fabrication practices
- Produces drawings that are clear, practical, and ready to build
✅ The Bottom Line
AI can assist drafting workflows, but it does not replace:
- Fabrication knowledge
- Engineering judgement
- Workshop experience
The goal is not to produce more drawings faster.
The goal is to produce the right drawings for how the steel is actually fabricated.
