Speed Up Corridor Target Mapping in Civil 3D with the Hidden “Set All Targets” Feature
A corridor that is clearly visible in plan view and profile view does not appear in section views created along sample lines. The section views are blank or missing expected corridor geometry.
Feature lines added as breaklines to a surface have no impact—elevations and slopes remain unchanged.
After updating or refreshing a Data Shortcut for a surface, the surface disappears from the drawing or shows as unresolved.
