If you’ve ever wondered how to harness the full potential of Tekla Structures beyond its
default features, understanding the Tekla Open API is essential. This tutorial will guide you
through the basics, share practical tips, and introduce you to the world of programming
within Tekla’s environment.
What is the Tekla Open API?
At its core, the Tekla Open API (Application Programming Interface) is a set of
programming tools and interfaces that allow developers to interact with Tekla Structures
programmatically. Through this API, users can automate design processes, create custom
plugins, and integrate Tekla with other software solutions.
Unlike typical software where users are limited to GUI-based interactions, the Tekla Open
API opens up the underlying data and operations, making it possible to manipulate
models, drawings, and reports with code. This flexibility is a game-changer for companies
wanting to optimize their workflows and reduce manual errors.
Why Learn Tekla Open API?
Learning the Tekla Open API brings several advantages:
**Automation of repetitive tasks:** Save significant time by automating model
updates, drawing generations, and report extractions.
**Customization:** Tailor Tekla to fit your company’s specific processes rather than
adapting your workflow to the software.
**Integration:** Connect Tekla Structures with other tools such as ERP systems,
estimation software, or project management platforms.
**Innovation:** Build new functionalities that may not yet exist in the standard
Tekla release.
**Competitive Edge:** Being proficient with Tekla Open API can distinguish you as a
valuable asset in the structural engineering and BIM community.
Getting Started with Tekla Open API Tutorial
Before jumping into coding, it’s important to set up your environment correctly and
understand the basics of how Tekla API works.
Prerequisites
**Basic programming knowledge:** Familiarity with C# or VB.NET is highly
recommended since Tekla Open API is built on .NET Framework.
**Tekla Structures installed:** Ensure you have Tekla Structures installed on your
computer. The API works with specific versions, so check compatibility.
**Tekla Open API documentation:** Download or access the official Tekla Open API
documentation from Trimble’s developer website. It provides detailed class libraries,
sample codes, and guides.
**Integrated Development Environment (IDE):** Visual Studio is the most common
IDE used for developing Tekla API applications.
Setting Up Your First Tekla Open API Project
**Create a new C# Console Application** in Visual Studio.
1.
**Add references to Tekla Libraries:** Add the Tekla.Structures.dll and other
2.
relevant assemblies found in the Tekla Structures installation directory.
**Set up your code to connect to an open Tekla model:** Use the
3.
`Tekla.Structures.Model.Model` class to access the current model.
**Write simple code to read or modify model data:** For example, retrieving all
4.
beams or creating new parts programmatically.
Here’s a very basic example snippet to get you started:
```csharp
using Tekla.Structures.Model;
class Program
{
static void Main(string[] args)
{
Model model = new Model();
if (model.GetConnectionStatus())
{
M o d e l O b j e c t E n u m e r a t o r
a l l B e a m s
=
model.GetModelObjectSelector().GetAllObjectsWithType(ModelObject.ModelObjectEnum.B
EAM);
while (allBeams.MoveNext())
{
Beam beam = allBeams.Current as Beam;
if (beam != null)
{
System.Console.WriteLine("Beam profile: " + beam.Profile.ProfileString);
}
}
}
else
{
System.Console.WriteLine("Failed to connect to Tekla Structures model.");
}
}
}
```
This snippet connects to the open Tekla model, fetches all beams, and prints their profile
names.
Exploring Key Concepts in Tekla Open API
Understanding the core components of the Tekla Open API will make your learning curve
smoother.
Model Objects
Almost everything in Tekla Structures is represented as a model object — beams,
columns, plates, bolts, welds, and more. The API allows you to create, modify, or delete
these objects. Each object type has specific properties and methods.
Model Object Selector
This tool helps you query the model to retrieve specific objects based on type, property,
or spatial location. It’s essential when you want to automate inspections or modifications
of particular model elements.
Drawing Manipulation
Beyond the 3D model, Tekla API lets you control drawings. You can automate drawing
creation, update views, or extract information from drawings, enhancing your
documentation workflow.
Event Handling
For advanced users, Tekla Open API supports event handling, allowing your plugin or
application to respond dynamically when certain model changes occur, such as part
creation or modification.
Practical Tips for Working with the Tekla Open API
Getting comfortable with Tekla Open API programming can be challenging at first, but
these tips will help you along the way:
**Start small:** Begin with simple tasks like reading model data or creating basic
parts before moving to complex automation.
**Use the Tekla API examples:** Tekla provides sample projects that you can study
and modify.
**Debug smartly:** Since your code interacts with a live model, always test on non-
critical models or copies to avoid data loss.
**Stay updated:** Tekla Structures and its API evolve regularly. Keep your
development environment and knowledge current.
**Leverage the community:** Join forums, user groups, and developer communities
focused on Tekla. They’re invaluable for troubleshooting and inspiration.
**Document your code:** When developing custom tools, clear documentation
ensures maintainability and ease of updates.
Common Use Cases for Tekla Open API
The versatility of the Tekla Open API means it can be applied in numerous scenarios:
**Automated Quantity Takeoff:** Extract material quantities directly from the model
to speed up estimation.
**Custom Part Creation:** Develop parametric parts that fit specific project
requirements.
**Model Validation:** Implement your own checks to ensure the model complies
with company or project standards.
**Data Export/Import:** Seamlessly move data between Tekla and external
systems, like ERP or scheduling software.
**Batch Drawing Production:** Generate or update dozens of drawings
automatically after model changes.
**Integration with Cloud Services:** Connect Tekla models to BIM collaboration
platforms via APIs.
Example: Automating Beam Creation
Suppose you want to create multiple beams programmatically along a specific path. Using
Tekla Open API, you could write a script that defines the start and end points, assigns
profiles, and inserts beams into the model.
This kind of automation not only speeds up model creation but also reduces human error
and maintains consistency across projects.
