“Lightning BIM automatic bar arrangement” that reduces bar arrangement man-hours by up to 90% Implemented a large-scale update that allows checking of fixing length within Revit
Accelerate construction DX in response to user requests

Arent (Headquarters: Chuo-ku, Tokyo, President: Hiroki Kabayashi), which promotes highly difficult DX by engineers, has developed the Autodesk Revit add-in “Lightning BIM automatic bar arrangement” that can reduce the man-hours for bar arrangement by up to 90%. ], we have updated various functions, such as being able to check the fixing length within Revit.

Product Summary
Arent has already developed an automatic piping software called “PlantStream(R)︎” for the plant industry. With the birth of this software, it has become possible to automatically route 1,000 lines in one minute, instead of the work that used to take 4 hours per line. With this high grasping power, modeling power, and implementation power, I worked on the development of the Revit add-in.
Reinforcement-related work that takes time. “Lightning BIM automatic bar arrangement” can reduce the work time by 90%. It is not just an automatic bar arrangement, but the industry’s first technology (= smart bar arrangement) can automatically avoid interference of bar arrangement based on the set rules.
“Lightning BIM Automatic Rebar Arrangement” was launched as a Revit add-in on April 22, 2022, and has already been fully introduced to many leading companies in the industry.
About this update
In response to requests from customers who have already used it, we have made various updates, such as being able to check the fixing length in Revit in “Lightning BIM automatic bar arrangement”. With this update, it is now possible to automatically arrange bars that ensure the gap and cover dimensions in accordance with the basic design, improve the accuracy of fitting, and significantly reduce the number of man-hours required for consideration.
1. Mechanical fixing update
Until now, it was only compatible with hook fixing, but the number of sites using mechanical fixing has increased, and at the same time, it has been updated in response to the growing needs. It is also useful in cases where there is a bottleneck in fitting, and when calculating the number of caps by integration.

2. Smart controller update
Editing rebars one by one has become easier, and useful functions have been added when modifying models.
In addition, by responding to gaps, we will notify you with an alert when the distance between rebars is insufficient. By displaying alerts, it is possible to reduce the number of cases where gaps and cover are insufficient when correcting reinforcing bar models, even for employees with little field experience. In other words, if anyone has a smart controller, it is possible to help them place rebar according to the rules set in advance.

3. Inspection function update
Underfill and underfix checks are finally possible within Revit. The fixation length is a bottleneck when considering how to fit the bar arrangement.
Failure to do so may lead to serious accidents in the future. By checking this on the BIM model in advance, we will understand and correct the lack of fixation.

4. Beam anchorage automatic extension
We aimed for a software that is closer to the field by increasing the level of detail.
In order to respond to the needs of construction study, we have made it closer to the intuitive feeling of the site and also supported it on the BIM model.

This update makes it easier, faster and more accurate to create rebar models. In particular, it is revolutionary to be able to check the fixation length within Revit.
Securing the fixed length of the panel zone is important in both the structural design and construction phases.
In addition, in many cases, rebars are arranged so that they are applied to rebars in a perpendicular direction at the site, but in this case, the anchoring position is automatically determined with a single click.
Also, with the smart controller update, a warning is now issued when the gap and fog cannot be secured.
Until now, we had to check the dimensions in 2D when we moved and put the rebar in, but now it is possible to examine the rebar fitting more intuitively in 3D. It eliminates the phenomenon that the reinforcing bars are too close to each other or the cover is insufficient. When I first started working at a construction company, after I finally finished drawing up a 2D floor plan, it came back red after being checked by a senior colleague. Tell me on the spot! I thought, but my seniors are busy and I don’t have that kind of free time. However, this Lightning BIM will tell you on the spot.

While receiving opinions from users, we are updating the functions of Lightning BIM one by one. We are adding improvements based on the opinions of those who are familiar with the industry, so it is rewarding for the development side, and I feel that product
development is moving in a better direction. In the future, we will promote development so that more and more people will introduce and use Lightning BIM, develop with the industry, and contribute to the improvement of work efficiency and next-generation work flow. ■ Akira Suzuki Customer Success

In addition to taking time to learn the Revit reinforcement function, it takes a lot of effort to deal with the corrections that occur every day.
In Lightning BIM, we have repeatedly implemented and updated original functions and related functions such as interference avoidance automatic bar arrangement function, smart controller, and fitting drawing generation.
In this update, the automatic bar arrangement function has been enhanced, usability has been improved, and it has evolved into an easy-to-use tool for users. We are planning to cover complex bar arrangement standards, so please look forward to Lightning BIM in the future.
