Parse the .drawio XML and modify mxCell elements by ID rather than editing the file with string replacement. Inventory all nodes, edges, switches, and feeders first, then change only the requested cells while preserving every other cell ID and geometry.

Add the LV busbar as a structural common bus for existing feeder taps only. Start it 12 pt before the first tap and end it 12 pt after the last tap, keeping every tap's original coordinate and centering each feeder endpoint on the busbar with no gap.

Transformers use two overlapping transparent rings with conductors terminating at ring boundaries, never entering the interior. Loads use filled triangular arrowheads on stems of at least 12 pt, centered and perpendicular to the triangle base, following IEC 60617 conventions.

Yes, but it builds topology only from the user's description and reports any ambiguity instead of guessing. It will not invent feeders, devices, ratings, switch states, or distributed energy resources that were not provided or explicitly requested.

Diagonal segments appear when connectors are not constrained to orthogonal routing. Route all feeders and branches as horizontal or vertical segments with right-angle bends, preserving a non-orthogonal source connector only when the requested change does not involve rerouting it.
