What is daylight in Autocad Civil 3D?

Mar 24 2016In-product view. Surface targets are used in a number of cases where the corridor needs to interact with a surface, such as when a slope is projected from a design elevation to the point where it intercepts an existing ground surface. This is referred to as daylighting.

What is daylight subassembly?

Default Tool Palette: Daylight Subassemblies. Daylighting outside of a boundary or obstacle. DaylightMultiIntercept: Daylighting that forces the cut or fill slope to pass through the surface multiple times to intersect at a more distant location.

What is a daylight line?

Daylight Line A line that intersects the target (a surface, a distance, an elevation, or a relative elevation) of a grading object. It is a line that connects the ends of the projection lines from the grading object’s feature line where they hit the target.

How do you extract a corridor from the feature line?

To extract one or more feature lines from the corridor select the corridor. On the context sensitive ribbon, Launch Pad panel, select Feature Lines from Corridor. The command line prompts you to select the Corridor feature line you would like to extract.

What is a corridor feature line?

About Editing Corridor Feature Line Connections



By default, Autodesk Civil 3D joins all points with the same point code along a corridor baseline and displays them as feature lines. You can modify how points are connected when a point code is used multiple times at consecutive stations.

What is grading tool in Civil 3D?

Creates grading by using prompts on the command line. The grading uses the current style and criteria. Creates a grading by copying the criteria and style from an existing grading object.

How do I create custom subassemblies in Civil 3D?

Simply select the modify origin command from the custom ribbon and select the point you created earlier to use as your modified origin. Then “Add Shape” to the subassembly. Select the subassembly and click “Add Shape” from the custom ribbon. Once complete, add this new subassembly to your corridor.

What is targeting in Civil 3D?

“ Corridors have the amazing ability to interact with other parts of your drawing. This allows them to change their shape to meet your design needs without having to do a lot of extra work. This is made possible through something called a target.

What is Autodesk subassembly composer?

Autodesk® Subassembly Composer for Autodesk® Civil 3D® provides an interface for composing and modifying complex subassemblies, without a need for programming. Subassembly developers can compose complex subassemblies visually and can simulate how the subassembly behaves with different target values and conditions.

What does daylight mean in grading?

A projected slope/grade from a design to a target surface is said to ‘daylight’ at the point where it meets/intersects the target surface.
