Work in 2D or 3D
Coordination is critical to maintain a tight construction schedule, avoid site errors and eliminate costly extensions. Building information modeling (BIM) gives drafters the ability to work in their familiar 2D drawing, while generating a 3D model. Functions like automatic bar placement and bending tools can cut the time it would take to design projects.
Here's what one of our customers said:
“When working with complicated geometrical conditions in conjunction with high reinforcement levels, complex reinforcement patterns often arise, which can be produced and also optimized considerably faster using 3D planning together with 3D animation.
But even with simple reinforcement planning, working in 3D is still worthwhile, especially when amendments are made, as an adaptation in the 3D model no longer has to be carried out manually in the sectional views. Allplan Engineering provides a significant advantage in such situations in comparison with 2D solutions.”
Automatic Clash Detection
Rebar detailing can be grueling work--especially if you’re using 2D CAD software for drafting. One fundamental flaw of working in 2D; limited visualization. If there’s rebar congestion or clashes, it’s nearly impossible to detect them in a 2D draft. But there is good news for detailers, and it’s spelled B-I-M.
Building information modeling (BIM) gives drafters the ability to work in a familiar 2D drawing method, while also generating a 3D model. Not only that, but functions like automatic clash detection help detect errors in the design stage, so they can be resolved before they cost the project time and money in the fab shop or onsite.
Rebar detailing can be challenging--especially if you’re using 2D CAD software for drafting. If changes are made to the draft, then all copies of that draft have to be updated individually. This doesn’t help engineers and detailers work together more effectively, and it certainly doesn’t help keep a project on schedule.
Allplan BIM software allows drafters to maintain their 2D working method, while also generating a 3D model. Then, all changes made to this model are automatically updated in real time. Everyone working on the project would see the most current version of the model in the software, avoiding the need to redo the draft from one discipline to the other.
Automate bar lists
Rebar detailing can be challenging work--especially if you use 2D CAD software for drafting and Excel for reporting. Not only does the design portion of the project take longer in 2D, but the reports, material take offs, and bar bending schedules have to be created manually in an entirely separate program.
This disorganization creates a greater likelihood of reporting errors, which could wreak havoc on the entire project. BIM software allows drafters to generate a 3D model from which all reports are derived directly. Bar bending schedules and material take offs can be generated with a few clicks of a button, without having to leave the program!
Reinforce complex shapes
Rebar detailing can be challenging work--especially if you use 2D CAD software for drafting. Not only does the design portion of the project take longer in 2D, but it becomes very challenging to reinforce a project with complex shapes.
This was certainly the case for the team that worked on the Stuttgart 21 rail project - one of the largest European infrastructure projects. The engineers were presented with an enormous challenge when designing the shell roof, supported by 28 geometrically complex, chalice-shaped columns.
Luckily, the engineers had the benefit of modeling the reinforcement in 3D using Allplan. They were able to produce 12,000 reinforcement drawings, all for one roof!

An Introduction to Rebar Detailing
The question, “what do you do for a living?” is a simple one that any working professional can answer. however, there are professions within the AEC industry that are not commonly recognized—a rebar detailer is one of them.
The Professional Problem Solvers
Rebar detailers are not only interpreters, the core of their skill set lies in problem-solving. They put the pieces of a puzzle together to create the right drawing, and in turn, the correct fabricated rebar.
The Future of Rebar Detailing
In the AEC, there is a controversy over 3D and BIM, vs 2D. While 3D is a component of BIM, it is not BIM in and of itself.
