Classification demo
Select components, drag the line-angle slider, and choose bundled or single conductors. The elevation view and plan view update live — including the guy wire appearing when the resultant force requires one.

⚠ Pin insulators are not rated for angles ≥30°. The transverse bending load on the pin cap exceeds its strength — deadend strain insulators and double-deadend framing are required at this deflection.

How the classifier read it
API correspondence: /circuit-classify reads insulator geometry and
voltage_v from the UPM.
/framing-classify walks crossarm count and attachment positions.
/guying-validate derives the residual tension vector from each span and checks guy coverage — the plan-view resultant arrow is exactly that vector.
