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.
