What does daylight mean in Civil 3d?

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.

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 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 does daylight mean in construction?

Daylighting is the controlled admission of natural light, direct sunlight, and diffused-skylight into a building to reduce electric lighting and saving energy.

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.

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.

How do I create a ditch Assembly in Civil 3D?

How to create an assembly with a ditch that targets a line or a surface in Civil 3D

1. Stating with an Assembly, add a “LinkSlopeToSurface”.
2. Add a “MarkPoint” at the end of the LinkSlopeToSurface and give the marked point a point name.
3. Click on the assembly and add select “Add Offset”.

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 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.

How do you grade a surface in Civil 3D?

On the Grading Creation Tools toolbar, click Select a Criteria Set. In the Select A Criteria Set dialog box, ensure that Basic Set is selected. Click OK. From the Select a Grading Criteria list, select Grade To Surface .

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.
