YOU → REVITAI-assisted workflow concept
Create a G+3 office. Add levels and grids, build the structure, then create floors, walls and the facade.
First, define the levels and the structural grid.

A different way to work
From connecting nodes
to creating
what comes next.
Dynamo gives your ideas a structure. Python gives your logic a language. AI introduces a new way to express your intent.
At BIM Era Academy, build the skills behind the experience.
Find your learning path ↗A new way to work
Repetition is a task.
Automation is
a skill.
You already understand the model. Now understand the logic that makes it work for you.
At BIM Era Academy, learn to turn repeated Revit work into graphs, scripts and tools you can save, test and use again.
Explore BIM automation01
See the data behind the model.
Understand elements, parameters and the conditions that matter to your workflow.
02
Build the logic yourself.
Connect Dynamo nodes, express a rule in DesignScript, or write it with native Revit API Python.
03
Create an asset you can reuse.
Keep a tested graph or script, refine it for your project, and check the output every time.
THINK → BUILD → CHECK → REUSE

One task.
Three ways
to solve it.
Find ducts longer than 4.5 metres. The intention stays the same. The way you express it evolves.
Connect the logic. Read a value, apply a condition, and keep the elements that match.

Still have a question? Our team can help.
Talk to BIM EraDo I need coding knowledge to start?
No prior coding knowledge is required for Level 1. Dynamo introduces the logic visually, and the course starts from the basics. Level 2 builds on that foundation with native Revit API Python.
Which course is right for my experience?
Start with Level 1 if you are new to automation. If you already use Dynamo, discuss Level 2 with our expert. Choose Level 3 for C# add-in development or AI for Revit for a focused introduction to AI-assisted workflows.
Can I join AI for Revit directly?
Yes. AI for Revit is designed for working professionals. Dynamo and Revit API knowledge help you understand and check automation more deeply; our expert can recommend a starting point based on your experience.
When do the classes happen?
Regular training is scheduled from 8:30 PM to 10:30 PM IST. AI for Revit is planned for weekends. Ask the admissions team to confirm the next batch and the exact weekend session timings.
