Enable Curved Vertices on Extracted Dynamic Feature Lines from Corridors

[Beka_Tchigladze]

When extracting a feature line from a corridor baseline (e.g., for pile walls, retaining walls, or other angular structures), Civil 3D currently does not allow curved vertices at sharp corners while maintaining a dynamic link to the corridor. This limitation breaks the workflow when trying to apply daylighting around corners.

In real-world design, corners are rarely solved with perfect perpendicular daylighting. Instead, a tiny curve or fillet at the vertex would better represent the actual geometry and allow smoother transitions—especially when sweeping daylight around wall subassemblies.

Problem:

• Corridor corner solving fails when trying to daylight from a corridor baseline with sharp angles.
• Extracted feature lines are strictly linear at vertices, causing perpendicular daylighting that doesn’t reflect real corner cuts.
• To add curves, users must break the dynamic link with the corridor—losing parametric control and design efficiency.

Proposed Solution:

• Allow users to add a tiny curve or fillet at vertices of extracted dynamic feature lines from corridors.
• Maintain the dynamic relationship with the corridor even after adding the curve.
• This would enable realistic corner daylighting and smoother subassembly sweeps without sacrificing corridor intelligence.

Benefits:

• Preserves dynamic corridor workflows.
• Enables realistic corner geometry for daylighting and wall assemblies.
• Eliminates the need to manually rebuild geometry after breaking links.
