Demonstrates advanced 3D assembly logic using conditional insert constraints (`insopp`) rather than absolute coordinate transformations. Flanged segments and the control valve are sequentially linked by programmatically generating instance references with `@Concatenate` and `$index`. This showcases a robust strategy for linear routing, splitting pipe segment arrays around a variable-width inline component (supporting gate or globe valve types) while dynamically calculating individual pipe lengths to maintain a fixed total assembly length.
