Exploding means that you ungroup the objects of an existing component. This can be useful when you want to create custom components more quickly. Once the objects are detached, you can modify them to suit your needs and then create new custom components using these objects.
Select the component you want to explodeto ungroup the objects that are parts of another object or a component
In Tekla Structures, it is possible to explode components, cast units, assemblies, bent plates, parts that have attached parts, and drawing shapes and plugins.
The exploded objects cannot be reverted back to the original group.
