Edge Beams in Grid Structure

Hi all

I have created a grid shell, but would like to change the dimensions for a given beam. In this case the edge beams.
How can I explode the structure and choose the beams I want to increase in size?
It is the beams around the opening on the picture below.

Hi user! Would you upload the sketch to have a look? If the sketch is too messy, complex or simply you can not disclose it for some reason, perhaps you would prepare and upload a simple example. This will increase the chances someone helps you. :slight_smile: Best,

Hi @user2746, as @Vigardo, uploading your sketch would help.

However you can simply define different types of elements by separating those edge beams into different components or into different branches.
