how to draw ditch in civil 3d

This subassembly inserts a flat or V-shaped ditch with user-defined horizontal and vertical control parameters.

This subassembly can also include an optional lining material.

Attachment

The attachment signal is at the within edge of the first link. This will exist either the inner buffer or the foreslope link of the ditch if the inner buffer width is cypher. This is typically connected to the outside border of a shoulder.

Input Parameters

Notation: All dimensions are in meters or anxiety unless otherwise noted. All slopes are in run-over-rise form (for case, four : 1) unless indicated as a percent gradient with a "%" sign.

Parameter	Clarification	Type	Default
Side	Specifies side to insert subassembly	Left/Correct	Right
Include Ditch	Specifies to use the ditch in cutting and fill, fill up only or cut simply	Selection list: a)Cut/Make full, b) Cutting, c) Fill up	Cutting/Fill
Ditch Width	Width of the bottom of ditch. Use zip for a Five-shaped ditch.	Numeric, positive	1 m iii ft
Ditch Depth	Depth of Ditch	Numeric, positive	i m 3 ft
Foreslope Slope	Slope of the forepart-of-ditch link (x : i). This link is ever inserted downwardly.	Numeric, positive	4 ( : 1)
Foreslope Buffer Width	Allows a Buffer to exist placed before the Foreslope (goose egg to omit)	Numeric, positive	1 m 3 ft
Foreslope Buffer Slope	Slope of the foreslope buffer	Numeric, positive	-6 (:i)
Backslope Slope	Slope of the back-of-ditch link (x : one). This link is always inserted upwards.	Numeric, positive	four ( : 1)
Backslope Buffer	Allows a Buffer to be placed backslope the backslope (zero to omit)	Numeric, positive	1 yard 3 ft
Backslope Buffer Gradient	Slope of the backslope buffer	Numeric, positive	six (:1)
Place Lined Textile	Specifies to place optional fabric lining forth daylight links. You can cull All Links or None.	String	None
Gradient Limit 1	Specifies the slope limit until which the associated fabric lining is placed	Slope	i : 1
Material ane Thickness	Specifies the thickness of lined material. This thickness is measured perpendicular to the side of the slope.	Numeric, positive	12 inches
Textile one Name	Specifies the proper noun of the cloth applies for lining along grading links	String	Rip Rap
Gradient Limit 2	Specifies the slope limit until which the associated material lining is placed	Gradient	two : ane
Material 2 Thickness	Specifies the thickness of lined material. This thickness is measured perpendicular to the side of the gradient.	Numeric, positive	half dozen inches
Material ii Name	Specifies the name of the textile applies for lining along grading links	Cord	Rip Rap
Slope Limit 3	Specifies the gradient limit until which the associated textile lining is placed	Gradient	four : 1
Fabric three Thickness	Specifies the thickness of lined material. This thickness is measured perpendicular to the side of the slope.	Numeric, positive	4 inches
Textile 3 Proper noun	Specifies the name of the material applies for lining along grading links	String	Seeded Grass

Target Parameters

This section lists the parameters in this subassembly that can be mapped to one or more target objects, such as a surface, alignment, or profile object in a drawing. For more information, see To Specify Corridor Targets.

Parameter	Description	Status
Ditch Inner Edge Alignment	May be used to override the stock-still width of the foreslope buffer. The following object types can be used as targets for specifying this: alignments, polylines, feature lines, or survey figures.	Optional
Ditch outer edge Alignment	May be used to override the fixed width of the backslope buffer. The following object types can exist used as targets for specifying this: alignments, polylines, feature lines, or survey figures.	Optional
Ditch Bottom Profile	May be used to override the stock-still foreslope and backslope widths. The following object types can exist used every bit targets for specifying this elevation: profiles, 3D polylines, feature lines, or survey figures.	Optional
Target Surface	Surface used to determine if the ditch is in cutting or fill up. The following object types can be used as targets for specifying this surface: surfaces.	Optional

Behavior

This subassembly will insert a simple ditch shape (either flat lesser or V-shaped ditch) with optional foreslope and backslope buffers. The location of the inner ditch border tin can exist specified with a fixed width, or with an optional alignment. The ditch depth tin can exist specified with a fixed height, or a profile tin exist assigned to control the depth. The Cutting/Fill up Exam point is P3. Depending on the Include Ditch input parameter, the ditch volition simply be placed in cut, fill, or both cut and fill.

Annotation:

In Autodesk Civil 3D 2010 and previous versions, the Material Thickness parameter was measured vertically. In Autodesk Civil 3D 2011 and later, this parameter is measured perpendicular to the link. Therefore, if you open a drawing containing these subassemblies that was created in Autodesk Ceremonious 3D 2010 or prior in Autodesk Civil 3D 2011 or later, and then rebuild the corridor(southward), this parameter will be changed to reflect the new behavior. Whatsoever volume reports that use this subassembly will be updated to reverberate the new beliefs.

Layout Way Performance

In layout mode, this subassembly displays all of the links comprising the ditch with the parameters set as input by the user.
