Surface Modeling & RoadCalcSurface modeling is used to generate a topographic map.

It creates the surface model from physical features of the original ground survey points and their respective elevation.

Surface Modeling & RoadCalcIn highway geometric designs, the RoadCalc is the basic program package used for this purpose.RoadCalc deals with roadway geometric design, earthwork computation, and drafting capabilities.

Getting Started

Click on Eagle Point Icon

Click on create new project

Click next

write project description etc and click FinishClick and save the drawings inthe required folder

Click ok

Click products Surface Modeling

Surface Modeling sub window is opened

In surface modeling window click on prepare import ASCII Points

click

Go to the folder where the required data file is saved and click open

Click Apply

Point are transferred to AutoCAD

Draw boundary around the points by polyline

In Surface Modeling Window click on Triangulate Surface Model.

Click

Click on new Surface model, give name to surface and close the windowNew Surface Model

Check Display Model and Place Triangles and then click Apply

The AutoCAD command bar will ask for Select Object

Select the whole object and press enter

AutoCAD is asking for selection of boundary,Select the boundary and close the window. Triangles will be drawn.

To draw contours of the required data, click on Contours Make intermediate & Index

In drop down list select the required surface name which was defined in previous stepsCheck Use Screen DisplayCheck User Defined Boundary and click Apply

AutoCAD is asking for Boundary selection. Select boundary. Contours will be drawn

Contour lines are shown.In surface modeling window, click contours Annotate.. For displaying the elevation values of different contour lines.This is all about Surface Modeling

RoadCalc.Click on new project

Highlight the RoadCalc Sub-project and click Next

Write description of project and click Next

Now click Finish and then click ok

RoadCalc sub-Window is opened

Draw the polyline as your desired Alignment.

From RoadCalc Window click on Alignment Convert objects to Alignment.

The command line will ask for Selection of object,just click on the polyline drawn for Alignment.

The command line will ask for picking the point near the beginning of alignment.

On clicking the beginning point following window will appear.

Click on apply. The polyline will automatically change its color to RED, which means that your Alignment is converted to element.

The Alignment (NSL) color is changed into RED

Click Cross-sections Extract Cross-Sections.

You can change the station interval Then click ok

Check the Orig_Surface, also you can change the Corridor EdgeClick ok Mark all the stations if unmark

Stations are marked according to given data

Curves settingIn RoadCalc window, click Alignment Edit data.

Click Click on Curve Data to edit the different parameters of curve

Click horizontal speed tables for data inputClick

Below table shows different parameters of horizontal based on Speed Select the required design speed for horizontal curve, software will give you different parameters automaticallyClick

Eagle point will ask for at which intersection you want to draw a curve.Select All, and click OK.After clicking ok, curves will be drawn at all intersections according tothe data entered

In RoadCalc window, click Profiles Extract from Surface Model

In profile name select centerline and in from surface model select surface1,then click ok

AutoCAD command line ask for object selection.Select the centerline alignment and press enter.In command line write Z E Alignment is converted to profile (NSL)

Below line shows the Original Ground Profile i.e. NSLNow we will draw the Suitable Formation Level

Below white line is the required FL.

In RoadCalc window, click Profiles Convert object to Profile

AutoCAD command bar ask for object selection.Select FL and press enter

Click next

Select centerline in profile dropdown list, and click Finish

The FL colored is changed which shows FL alignment is converted to profile

Click profile Original Ground Profiles..

The NSL color is changed to GreenNSL Green lineFL Red line

Now we will construct sections for different layers Click Typical Sections Construct Typical Section

Name is given to different layers i.e. awc, abc, sbc etc

Click on precision input

Put input values for cross-sections.i.e. width and slope of carriage way, shoulder.Center line

Copy section from right to left as shown below

Click define Typical Section

Highlight awc and click OK

AutoCAD is asked for pick point in awc boundary

In Road Calc Menu bar click on Process Manage Condition tables

Click on new condition table and give name to condition table. Click OK < close.

In Road Calc Click on Process Edit Design Locations

Click new both in Typical Section Location & Condition Table Locations and put Zero in station values in both cases. And click close.

Click on Process Run Design

click Run and then close.

In Road Calc Menu, click Output Cross-Section Sheets.

click New Cross-Section Sheets

Just click OK

X- section sheets

Click Output Plan and Profile Sheets.

Highlight any section and click on view tool
