Solid wireframes rendered every triangle edge of the tessellation, so a curved solid read as a dense mesh instead of its real outline. Now each ACIS solid's B-rep face-boundary edges are collected from the SAT `edge` records (straight edges as segments, ellipse/circle edges sampled along their bounded arc), body-transformed and split into the double-single pair, and stored on the MeshLodSet. The block-instance and top-level offset paths transform these edges alongside the mesh vertices. The batch builder routes a solid with feature edges into a dedicated LineList vertex buffer and skips its triangle wireframe; a mesh with no B-rep edges keeps its triangulation edges. Edge colour follows the display mode: the flat `fs_edge` shader draws the entity colour in the lines-only modes (wireframe, hidden-line) and a `fs_edge_black` twin forces black for the edge overlay in filled render modes. Verified: the Clinic storefront arch bars now yield ~14-16 clean edge segments (vs the full triangulation) bounded to the solid's true extent. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
