Only surface border and points with description *DI* (Ditch) will remains.

Create a new layer for break-lines called ‘V-NODE-BRKL’ as per NCS.(NCS stands for National CAD Standards)

Use 2D Object snap (Node), Start to draw 3D Polyline and join DI points.This is the first Break line created in the drawing.

Repeat the procedure to create other break lines for various point groupsone by one.

*di*- ditch, *dw*- drive way, *ep*- edge of pavement, *er*- existing road,*sw*- side walk, *tb*- top of bank, *td*- top of ditch, *to*- slope toes,*walk*- walk way, *wall*- wall

Change scale to 1:200 or 1:250 to see points more clearly.Type REA(REGENALL) in command line after including next break point.

Horizontal AlignmentThe Horizontal Alignment is the first DESIGN ELEMENT.

• Horizontal Alignment is the centerline of a roadway passing through certain points in a specific direction and having a certain length

• Transitional Curves (Spirals)- they help in smooth transitioning between a tangent and a curve ( or between a curve and a tangent)

• The elevation of a horizontal alignment is zero (0)

[Components]

• Tangent : fixed length, specific direction, start and end points

• Curve : fixed radius, specific curve length, start and end points

• Spiral : variable radius, fixed length, start and end points

[Horizontal Alignment]

Create Existing Ground Profile

• Existing Ground Profile is a longitudinal cross section along a horizontal alignment passing through a surface (existing ground)

• REQUIREMENTS:• EG Surface• Horizontal alignment passing through the surface

Create Finished Ground Profile• It is the proposed ground profile.• It is the designed vertical alignment created in a vertical plane so as to provide a comfortable ride

along the centerline of a roadway.”• Two Parabolic Curves (no radius - constant rate of change of slope) are in a FG Ground Profile:

• Crest Curve and Sag Curve

Create Kanaka-Assembly-1 : Curb & Gutter, Side walks & Slopes on both sides.

Create Assembly

Right side – Curb & Gutter, Side walk and Slopes Left side- Shoulder and Slopes.

[Kanaka-Assembly-Half-way]

Create Kanaka-Corridor-1 Standard style and Kanaka-Corridor-2(Split Region) for Assembly Half-way.

Create Corridor

• It is a graphical representation of all design elements used in road/highway design

• The previously created assemblies are applied to the corridor in order to obtain accurate cut an fill volumes

• Finally intersections are created also to obtain cut and fill volumes

Create IntersectionIntersections are created in order to provide a smooth transition for all vehicles. We used a minimum of 15 m to allow for trucks.

To get Enough Survey Data – Extend Surface for this Project.

Extend Surface coverage area

Cross Section

Cross sections are the sections created perpendicular to the direction of a roadway. They have to be created at regular intervals on tangents, curves and spirals.
