A click in the viewport picks what is under the pointer through the selection filter (the selection bar, top centre): geometry faces, edges, vertices and bodies, or mesh nodes, element faces and elements. Shift adds, Cmd/Ctrl adds or removes, a click on nothing clears, Escape clears; with Box on, a left drag selects the visible nodes, element faces or elements inside the box. What a click would pick is highlighted under the pointer with its name beside it. The selection is kept in the model's persistent terms: geometry by name (GeometryRef, named through the mesh's geometry tags or the drawn bodies' face names), so it survives a remesh, and the mesh by label (labels the model loses drop out). It reads as a set's members. Picking runs on the CPU against the triangles both renderers draw. The selection and the hover are drawn as an overlay in the theme's new pick_selected and pick_hover colours (light and dark), outlined; the GPU draws it as a second small layer, so a hover change uploads only that. Command forms that apply to part of the model (sets, boundary conditions, loads, sections, couplings) get a Target row whose Use selection fills the members, or makes a set of the selection and names it. A right click offers Create set from selection. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm

//! The 3D viewport: the model drawn on the GPU (or on the CPU without one), camera navigation,

|

//! drag (or Shift + left drag) pans, the wheel or a pinch zooms at the cursor, a double click or F
