Three root causes caused all geometry and UCS arrows to disappear: 1. TruckObject::Lines and TruckObject::Text variants returned world-space f32 coordinates without applying world_offset, so fit_all() computed bounds spanning from local space to UTM world space (~4 M m), placing the camera impossibly far from all visible geometry. 2. Ray/XLine entities with unnormalized direction vectors (common in some DXF exporters) produced astronomically large far-point coordinates (up to 1e28) that overwhelmed the camera fit even after the offset fix. Fixed by normalizing the direction vector before multiplying by DISPLAY_EXTENT. 3. Origin-stuck corrupted entities (coordinates ≈ 0 in world space become ≈ -world_offset in local space) pulled the fit_all() bounds far from the actual drawing. Fixed by computing local_extent_max from EXTMIN/EXTMAX (10× safety margin) and skipping points outside that range in fit_all(). Additional hardening: wire_gpu.rs now skips ±inf segments (not just NaN), and snap_pts/key_vertices in all TruckObject variants are offset-corrected.
