Use the same script to extract wires.  Select a cloud and then a point to start the extraction. The electric line is extracted using a point on the line and a sampling step that includes the line. You could use this script to extract not only wires but almost any line object. For example some kind of fences also.

For extraction markers on the road same as for road lines, the first step should be filtering point clouds, next. we can use geometry tools to fit them in the cloud where it is possible to represent the desired elements with basic rectangle and circle objects. Also, we can use combinations of offset, transition, rotation, and other transformation tools to speed up the processing.

To extract more complex shapes use the Planar Countour command, the command allows extracting planar contours from meshes and clouds. After extraction applies the Resample Polyline tool to them and specifies desired number of vertexes. The polylines will look much better.

To represent the hardest shapes use the manual tools for creating polylines and then copy that set of polylines into other locations.

For curbstones, we also can go with manual ways and automatic ways with scripts. For manual extraction click the Draw polyline tool and set the Snap to the Ground point for extracting the Lowest line of the curb, for the highest line set the snap to the Highest point.

For the automatic way, you need to have at least one polyline that will represent the direction of the line that should be extracted. You can specify two lines (the bottom and upper parts of the curb) and then run the pre-installed Curb extraction script. The algorithm extracts the curbs at individual points defined by the sampling step. This tool works pretty well, especially with the clean and accurate point cloud from the TRK.

A few more tools that you could try for curb extraction purposes based on mesh analyses, so for them you should create a mesh from the surface and curb points. Thanks to the classification in Pegasus Office, the point cloud is already split by relevant layers. All that you need to do is select the layers with the point cloud, group them and click the Scan to Mesh tool. It's one of the easiest ways to create a mesh.

When the mesh will be created we can try to extract all lines with the Multiple Breaking Lines tool. This command offers the possibility to extract all the breaking lines (or feature lines) from a mesh. The resulting lines are divided into two sets:

• The convex lines, in red, correspond to crest geometries,

• The concave lines, in blue, correspond to ravine geometries.

One more unusual way to extract lines which I showed in Scan to Plan tutorial is to make a slope analysis, then segment the mesh by color and extract all borders as polylines. Anytime when we work with the automatically extracted lines, we should apply on them some filters to make them more smooth.

After the classification point cloud, we got layers with points relevant to the road signs and poles. Basically, it's just cylindrical objects and we can use the Best Fit Cylinder or Best Fit Circle tools to extract information about their geometry. 

• But before that, I prefer to segment point clouds closer to the ground, because upper points contain elements not relevant to the cylindrical objects. You can use previously created ground for that and the Separate According Distance filter. This command explodes one cloud into two parts using a selected object and the defined distance from that object. Use different distances for signs and for poles, based on their shapes. The main goal here is to get a clean point cloud of cylindrical objects. 

• Use the Segment by distance filter to split one big point cloud to separate files. 

• Next, use the Best Cylinder tool and check the One shape per input option. That tool will give you the right geometry object for all selected elements with one click. 

• I prefer also to convert these objects to mesh with the Mesh from Object tool and extract their holes and borders as polylines. 

• Then Select the lowest part of each element and project it to the ground. It will give us not only X and Y information but also Z values for each element. 

If your final deliverable will be a 2D plan or 3D model in AutoCAD Civil 3D, then you can create the dynamic block with a different type of visibility and use multiple placements of this block based on information extracted from Cyclone 3DR. Select all polylines that represent cylindrical objects and apply the Best Cylinder tool to them. Set the One Shape per Input option and then use the below script to extract the center position of each geometry element.

When the position of each element will be defined, copy it from the script window, then go to Civil 3D, select your block and click Copy tool. Paste to the command line previously copied elements and you'll see that the software will insert the block to each single coordinate, that you copied previously from Cyclone 3DR.

One more useful way of creating symbols on your topographic plan is the manual extraction of particular points and assigning them description codes with the Virtual Surveyor script from my colleague Kyle Palmer. This script allows you to label picked points in 3DR in the viewing window and store the points with a feature code and comment concurrently to the selection. I prefer to select ground point snapping mode when I'm using the script, to get all points with the right Z value. Try to use the same description codes as you have in your CAD software, it'll allow you automatically generate all symbols based on their description. In Civil 3D it's called the Description Key Sets, you can add there any symbols you want and add to the special code. When you'll import the coordinates of your points with relevant codes all symbols will be generated based on these sets. 

For tree extraction, first of all, we should define how we want to see the final result: as a 2D symbol of each tree, a 2D contour of all tree crowns, or as a 3D object.

For the 2D symbols, we can use the same tools we used previously

For the 2D contour we can use the same technique as I showed in the Scan to Plan tutorial:

• Project all tree clouds to the Ground surface

• Analyze Mesh vs Cloud and Segment the mesh based on the analyses color

• Subdivide the mesh and repeat the previous step 

• Extract all borders as polylines

• Later you could use the mesh to get all surfaces

For the 3D object representation uses the Region Grow Cylinder tool to represent the tree trunk and the Convex Hull to represent the tree Crown. This command computes the convex hull of a cloud, that is to say, a mesh that contains all the points. Later you could use all generated meshes to get crown volumes.

For buildings there are also different ways of representation, you can create a 2D plan or 3D model. In Scan to Plan tutorial, I demonstrated a lot of different workflows on how to extract 2D polylines from the cloud. Use the Scan to Plan tool and the Planar Section tool with a combination of editing polylines tools.

For the 3D model creation use the Building Extractor tool. This command allows you to create a simplified mesh based on planar parts of a point cloud or mesh. 

1. Click on the input object to extract planar areas and contours.

2. Validate the extracted planar contour. This will create a planar mesh.

3. Repeat both operations to create planar meshes as needed.

The connections between the extracted planes are calculated by default. However, you can force or remove some connections. To do so, all you need to do is drag one ball representing a plane onto another one to force the connection. In order to remove the connection, select the edge representing the connection and press the Delete key.

The user can manually define a plane by clicking n points (n >= 3) with the Shift key pressed. Pressing the Shift key will override the automatic plane extraction behavior. All points clicked with the Shift key pressed will be used to compute the best plane from these n points.

One of the common tasks it's also extracting contour lines. You can do it easily if you have a ground surface with the Countour Lines tool. Just select a mesh and run the command. 

1. Define the Step between each contour line

2. Choose the Range of the contours

3. Set the interval between major contours

4. Filter contours smaller than to remove irrelevant contours

Contours are created based on triangles so they could have rough shapes, to make them smoother use the Smooth Polyline tool.

If you prefer to create contours in other CAD software you can export the mesh as a LandXML file and use it in your CAD as you wish.

As additional deliverables, we can create different types of cross-sections. For the transverse profile create a trajectory first, then select it and run the Sections along Curve tool. This command computes a set of planar sections along a polyline or a curve. Specify:

•  Step of sections, you can define the step between sections and optionally a range using Custom. With a List of distances. You can type distances and/or click points in the scene.

• Searching distance to draw the sections only in the curve neighborhood. The value corresponds to a radius.

After creation, you can resample transverse polylines as you wish.

For the longitudinal profile, you can use the below script. This script provides functionality to unroll a 3D polyline so as to plot a longitudinal profile. 

1. Create a sample polyline to represent the trajectory of the road. 

2. Project it on mesh with the Projection tool

3. Run the script and select the projected polyline

The script will create the longitudinal profile, project it vertically on the horizontal plane, and compare both lines. Later you can disable the comparison if you want to leave only the profile polyline on the screen.
