This tutorial covers how to utilise some of GeoTools Build tools for creating Right-of-way / Pavements 

1. Open the drawing named lesson8.dwg which is located in your GeoTools Tutorials folder. This folder is located in the folder where you have installed GeoTools.

2. You should see a drawing (see Image 10-1) of a small layout of road center-line represented by 3D Polyline

Image 10-1

3. Now we will see how to create right-of-ways by offsetting the road center line on either sides by specified distance. 

Creating Right-of-ways

1. Click on menu GeoTools => Build => Make Right-of-way / Pavements or type GT_ROWMAKER at the command prompt.

2. This will pop-up the dialog box as shown below in (Image 10-2)

3. Type 20' Ft in Width of R-O-W box for offsetting the road center line 20' Ft on either sides. Then click on Select button for specifying the layer for offsetted lines.

4. This will pop-up the dialog box as shown below in (Image 10-3)

5. Choose the layer name Pavement and click on OK button this will bring you back to the dialog box as shown below in (Image 10-4) displaying the name of the layer Pavement. in ROW layer

7. Now click on Scan selected objects button and select the 3D Polyline press Enter key when done this will bring you back to the standard selection dialog box.

8. Lastly click on Apply button to offset 3D polylines on either sides with specified width and in selected layer. As shown below in (Image 10-6)

So we have learnt how to create Right-of-way / Pavement with the given road centerline. Now in similar method we will create Curb and
Shoulder

Creating Curb and Shoulder

For creating the Curb and Shoulder repeat the above steps from step 1 to 8  from Creating Right-of-ways by specifying offset distance 25' Ft for Curb and 
30'
Ft for Shoulder and select the appropriate layers i.e. for Curb select the Curb layer and for Shoulder select the Shoulder layer. This will create the Curb and Shoulder at 25' and 30' Ft respectively in selected layers as shown below in (Image 10-7)
