Question: How to correctly extend a structural element for connection purposes? In the example below, it is necessary to extend element C, notch it with the slope of the upper edge of beam B, but with a small gap from it to provide enough space for welding.

Answer: Never solve this using eccentricity of the element, as it could result in incorrect node geometry.

Instead, utilize the Cut operation. As the name suggests, it cuts elements, but it cuts them at the position you specify. This can shorten or extend the element.

Thus, we will notch element C with element B, selecting the 'Farther' option for the notch position, meaning the notch position is 'farther', or the upper edge of element B...

...whereby C will extend:

Next, specify the Offset to distance the upper edge.
