This tutorial covers some of the GeoTools Annotation tools for Annotating the polylines representing the electrical layout.

1. Open the drawing named lesson6.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 7-1) of a small layout of road under development represented by 3D Polyline.

3. Now lets see how to label the X,Y,Z co-ordinates of 3D Polyline at each picked point.

Labeling the X, Y, Z co-ordinates at each piecked point

  
1. So first set your Osnap setting to ENDPOINT, this will be useful to pick the points while labeling.

2. Next click on menu GeoTools => Annotation => Label Points or type GT_IDXYZ at the command prompt.

3. This will pop-up the dialog box as shown below in (Image 7-2).

4. Choose the options and type the values as shown in the above (Image 7-2) 

5. Click on the Select... button to choose the layer for annotating the vertices. This will pop-up the dialog box as shown below in (Image 7-12)

6. Choose POLE from the Select label layer dialog box and click on OK button to come back to the previous dialog box

7. Click on OK button on the Label layer dialog box you will be prompted to pick point object or press ENTER to pick individual points.

8. We will label the co-ordinates by picking the individual points so you press ENTER key

9.Now you will be prompted to Select point to annotate so go on picking the Vertices of the bottom 3D polyline. This is will label the X,Y,Z co-ordinates at the point picked. 
as shown below in (Image 7-3).

After learning how to label the X, Y, Z co-ordinates of each vertex , we will see how to label the slope distance of each segment in the 3D polyline.

Labeling slope distance in 3D Polyline

1. Click on menu GeoTools => Annotation => Label Polyline Segments or type GT_SEGLABEL at the command prompt.

2. This is will pop-up the dialog box as shown below in (Image 7-4).

3. Choose the options and type the values as shown in the above (Image 7-4).

4. Click on Distances... button under Label Formatting this will pop-up the dialog box as shown below in (Image 7-5).

5. Choose the options as shown in the above (Image 7-5). And click on OK button this will bring you back to the Label Pline/Spline/3Dface/Arc dialog box.

6. Now click on OK button this will pop-up the Standard selection dialog box as shown below in (Image 7-6).

7. Next click on Scan selected objects button and select the top 3D Polyline for labeling its segment lengths.

8. Lastly click on Apply button for labeling each segment length as shown below in (Image 7-7).

After learning how to label the slope distance of each segment in the 3D polyline. Now we will see how to annotate the ends of 3D polyline 
with symbol notation.

Annotate ends of Polyline with symbol notation

1. Click on menu GeoTools => Annotation => Annotate ends of Lines/Plines with symols or type GT_AnnotateEnds at the command prompt.

2. This will pop-up the dialog box as shown below in (Image 7-8).

3 Click on the button Block Name at curve start... this will pop-up dialog box as shown below in (Image 7-9)

4. Select the block name LOT and click on OK button this will bring you back to previous dialog box.

5. Now click on the button Block Name at curve end... this will pop-up dialog box as shown above in (Image 7-9).

6. Select the block name LOT and click on OK button this will bring you back to previous dialog box.

7. Choose the options and type the values as shown below in (Image 7-8A).

8. Click on OK button this will pop-up the Standard selection dialog box as shown below in (Image 7-11)

9. Now click on Scan selected objects button and select the top 3D Polyline.

10. Lastly click on Apply button for placing the Lot block symbol at the start and end point of the 3D Polyline selected.
