_draw_cnet_bodyplan: eliminated the longitudinal edges (same WL index across all stations) — in the body plan all sections are overlaid in the same y-z plane so those connections produce confusing diagonal spoke patterns radiating from bow/stern. Now only transverse section polylines are drawn as the muted control-net underlay. _draw_cnet_planview: likewise removed the redundant longitudinal layer (waterline contours) because layer-3 already draws them bold on top. Only the transverse station-direction edges are kept, which are the genuinely new information in plan view. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Visores 2D del plano de líneas del casco — con edición interactiva.
|
|
|
|
Tres widgets especializados basados en QPainter:
|
|
• BodyPlanViewer — secciones transversales (body plan)
|
|
• ProfileViewer — perfil lateral (líneas de agua, cubierta, quilla)
|
|
• PlanViewer — vista de planta (líneas de agua desde arriba)
|
|
|
|
Cada visor muestra la malla de puntos de control de la OffsetsTable.
|
|
El usuario puede arrastrar cualquier punto para modificar la geometría;
|
|
al soltar se emite la señal ``offsets_edited(OffsetsTable)``.
|
|
|
|
Soportan zoom con rueda del ratón y paneo con botón medio/derecho.
|
|
Doble clic restablece el encuadre automático.
