Link Array Tool ignores any transformations applied to a part after insertion

[hptsys]

Problem description

When a part is inserted into an assembly and transformed (rotated or moved) before forming a join, the Link Array tool ignores these positional and orientation changes. Instead of placing array instances relative to the joined state, the array generates using the part's initial insertion coordinates.

Workbench affected?

Assembly

Steps to reproduce

Example:
Insert a cube and a spring into an assembly. (File: Bug_of_assy_array.FCStd), Step1.png

Rotate the spring and join it to a corner of the cube. (File: Bug_of_assy_array_stage1.FCStd), Step2.png

Create the array using the spring. (File: Bug_of_assy_array_stage2.FCStd) Step3.png

Expected behavior

The Link Array should evaluate the transformed position and orientation of the part after placement/joining.

Actual behavior

The Link Array generates elements at the original, untransformed placement coordinates of the inserted part.

This is expected because link array creates links to the object.
But the placement of links is separated from the placement of the object itself. Such that the object and the link can have separated placements.

But I see the problem you are facing. I need to think about the best solution here.
