Automate BIM Tool Code Writing with Google Antigravity

1. Introducing Google Antigravity

Google Antigravity is an advanced AI assistant developed by Google DeepMind that can understand and write code in many different programming languages. In particular, Antigravity can automate coding for popular BIM tools such as Civil 3D, Revit, and AutoCAD.

Key benefits:  Increase productivity, reduce programming time, automate repetitive tasks, and ensure consistent code quality.

2. Applications for Civil 3D

Civil 3D is infrastructure design and documentation software. Google Antigravity can help automate coding for:

2.1. Road design automation

Create alignment and profiles automatically from terrain data
Automatic calculation of excavation and earthwork volume
Create standard cross sections
Export detailed volume report

2.2. C# code example for Civil 3D

// Tạo alignment tự động từ polyline
using Autodesk.Civil.DatabaseServices;
using Autodesk.AutoCAD.DatabaseServices;

public void CreateAlignmentFromPolyline()
{
// Lấy polyline được chọn
ObjectId polylineId = SelectPolyline();

    // Tạo alignment từ polyline
    ObjectId alignmentId = Alignment.Create(
        civildoc,
        “New Alignment”,
        polylineId,
        “Alignment Style”
    );
}

3. Application for Revit

Revit is the leading BIM tool for architectural and structural design. Google Antigravity supports:

3.1. Modeling automation

Create family parameters automatically
Place elements according to rules
Automatically update project information
Export data to Excel/Database

3.2. Python code example for Revit (pyRevit)

# Create walls automatically from lines
from Autodesk.Revit.DB import *

def create_walls_from_lines(doc, lines, wall_type, level):
    walls = []
    with Transaction(doc, “Create Walls”) as t:
        t.Start()
        for line in lines:
            wall = Wall.Create(
                doc, line, wall_type.Id,
                level.Id, 3000, 0, False, False
            )
            walls.append(wall)
        t.Commit()
    return walls

4. Application for AutoCAD

AutoCAD is the most popular CAD platform. Google Antigravity can write code to:

4.1. Technical drawing automation

Create blocks and attributes automatically
Automatic numbering
Create tables and captions
Export data to other formats

4.2. AutoLISP code example

; Create text automatically with increasing numbers 
(defun c:AutoNumber ( / pt num height) 
  (setq num 1) 
  (setq height 2.5) 
  (while (setq pt (getpoint “\nChoose the number point: “)) 
    (command “TEXT” pt height “0” (itoa num)) 
    (setq num (1+ num)) 
  ) 
  (princ) 
)

5. Workflow with Google Antigravity

Requirement Description: Specify the task to be automated
Select language: C#, Python, AutoLISP, VBA depending on BIM tool
Generate code: Google Antigravity automatically generates code
Testing: Review and test code in a real environment
Optimization: Ask Antigravity to improve the code if needed
Implementation: Apply to real projects

6. Practical benefits

Save time

Reduce coding time by 70-80% compared to manual methods. A task that normally takes 2-3 hours can be completed in 15-20 minutes.

High quality code

The generated code follows best practices, is fully commented, and is easy to maintain and extend.

Reduce errors

Automation helps reduce human error, ensuring consistency across the entire project.

7. Conclusion

Google Antigravity is a powerful tool that helps BIM engineers at T27 automate programming for Civil 3D, Revit, and AutoCAD. This not only increases productivity but also allows the team to focus on more complex, creative work and problem-solving.
