This article is also available in:
By following this step-by-step tutorial, you will learn how to design and code-check a structural steel connection using the BIM link between MIDAS CIVIL NX and IDEA StatiCa Checkbot.

1 Activation 

Since version midas Civil NX 2024 and newer, the API has been added, and due to this new possibility, the new link to IDEA Statica Checkbot was created.

In the following figures, you can see how to activate the link.

Now run midas Civil NX and open the new or existing project.

In the ribbon, in the last tab APPs, there is API Settings, where the Base URL and MAPI-Key are given. At first start, the MAPI-key is blank and it is essential to generate it by clicking on the Refresh button. The MAPI-Key is unique for every user and shouldn´t be shared with others. The Copy button can be used to copy them. 

Connect to the API.

2 Import to Checkbot

At first, run the linear analysis in Civil NX to get the internal forces. 

After analysis, you can import the whole model. To do so, select all the elements.

Alternatively, the connections could be imported one by one by selecting only one or more connections. The connections of the same typology are sorted into one arrangement or group.

More about the workflow in the Checkbot, see the article Checkbot – bulk BIM workflows.

Important note

The Civil NX still allows the export to IDEA StatiCa BIM for the detailed check of the concrete sections.
