Do you know, that… ?

Linear pattern in some respects it is very similar to Curve based pattern.

Let me explain.

In the linear pattern, you can choose For your reference, where to choose constant spacing or fixed number of repetitions.

Fixed spacing allows a number in the pattern to change automatically when the reference changes.

In this case, the reference is a vertex, so when extending an element, new instances in the pattern are automatically added. True to the moment, when the next occurrence does not fit, there is a pause, but that too can be solved with an equation.

The second option is a fixed number of pattern repetitions. That is, changing the dimension of the element, occurrences in the pattern are evenly distributed, but their number does not change.

 

You can get the exact same solution with a Curve-Based Pattern, where edge is the pattern reference.

What are the differences?

A curve driven pattern allows you to arrange elements along any curve (including 3D), line pattern only along the line (as the name suggests). In contrast, in a linear pattern (for your reference) you can define an end offset, and you can pattern in two directions independently.
