Clicking the Point button from the Create panel in the Action tab will open the Point Creation dialog.
The Snap Mode Panel offers twelve different options for snapping to points in the cloud in the open scene.
Cloud - No snap function is active. The vertex of the polyline will be placed at the cloud point nearest to the selected location.
Low - The point is placed at the lowest point (smallest z value) within the Snap Radius.
High - The point is placed at the highest point (largest z value) within the Snap Radius.
Low Edge - Snaps to the low edge of a feature, like a curb. A dynamic window in the upper left of the scene displays a cross section of the area within the Snap Radius and displays the high and low edge as red squares.
High Edge - Snaps to the high edge of a feature, like a curb. A dynamic window in the upper left of the scene displays a cross section of the area within the Snap Radius and displays the high and low edge as red squares.
Slope Bottom - Snaps to the bottom edge of a slope that is less than 45 degrees. This is useful for finding low edges on mountable curbs and other non-vertical features.
Slope Top - Snaps to the top edge of a slope that is less than 45 degrees. This is useful for finding upper edges on mountable curbs and other non-vertical features.
Average Point - This snap averages Northing, Easting and Elevation for all points within the Snap Radius and uses the averaged values for the coordinates for the new point.
End Point - Snaps the new point to the endpoint of an existing polyline.
Mid Point - Snaps the new point to the midpoint of an existing polyline.
Node - Snaps the new point to points placed in the drawing using Carlson Point Cloud Create Point.
Nearest - Snaps the new point to the point on an existing polyline nearest to the cursor location.
Feature points are specific types of features that Carlson Point
Cloud can automatically extract. These points are extracted as 3D
elements to reflect the feature selected and display the general
shape in the Point Cloud scene. The screen captures below show the
various 3D elements for each feature type. There are six options in
the Feature point drop list.
None - No Feature type is selected.
Tree - The user picks a point near the bottom of a tree in the scene and the trunk diameter, height, and drip line diameter are extracted and displayed as the description for the point.
Pole - The use picks near the base of a pole in the scene and the diameter and height are extracted and displayed as the description for the point.
Hydrant - The user picks near the base of a hydrant in the scene and the diameter and height are extracted and displayed as the description for the point.
Circle - The user picks anywhere on a vertical structure such as a pole and the diameter of the pole is extracted. The program the prompts for an elevation and the user can pick a second point for the actual elevation of the pole. This is useful when the bottom of the pole is obscured.
Corner - This feature places a point at the intersection of two building faces. The user picks the first flat building face followed by the second. The program then prompts for a third location to use as an elevation. The result is a point set at the intersection of the tow building faces at the elevation picked such as a the actual ground.
Hide Feature Points - When toggled on this command will "hide" or remove from the scene that points that make up the feature selected. For example, if feature type Pole is active and you select the base of a pole, the points that display as the pole in the scene will be hidden. A coordinate point is placed showing the diameter and height of the pole.
Use SZ Code - When toggled on this command will change the description displayed in the scene and stored in the Coordinate list. The new description is coded to take advantage of special codes in Field to Finish to more accurately display the features. Size or height, rotation and diameter or width. By setting up the Field to Finish file (.FLD) to place 3D blocks and use the special codes placed in the description by Point Cloud a more realistic and accurate 3D view can be created in CAD.
Draw Solid Feature -Note: If the Hide Feature Points is toggled on and features are selected the user will be prompted to update the cloud, save a new cloud or discard changes when closing the scene.
The Create Point panel displays options for creating a point.
In the Create Point panel you can choose the destination of points created using the Active List drop list. Points created will be added to the list displayed in the Active List. Three options are available.
Point Number determines the number to be assigned to the point. There are two options for numbering.
Increment Current will follow the standard numbering convention of Carlson Civil Suite (increment the number without any filler digits).
From Settings will use the prefixes and digits from the naming Conventions in the Project Settings
Clicking Code will bring up the PointCloud - Code Table dialog.
Pick
FLD File allows the user to set the current field-to-finish
file (.FLD). Once an FLD file is open the user can select a code to
use to create points by click the desired code and then clicking
the Green check mar.
The Field-to-Finish Linework panel allows you to specify properties of the next field-to-finish linework segment (if the current code table entry has linework associated with it). If your code does not specify linework you will receive a message that your code does not have linework associated. Once you clear the message dialog your point will be placed and the linework options will be set to None.
Once a code is selected from the Create Point panel the user may select one of the Field-to-finish Linework radio button options.
None no linework is created. This is the default when a Point code without linework is selected.
Start Line Begins a line using the parameters in the code table. Lines are only created for point codes that have linework associated with them.
Continue is selected as you continue adding points to the current field-to-finish linework.
Start Curve (PC) Sets the starting point for an arc. The arc will be drawn using the parameters in the code table.
Specify Vertex Position:
Places a point at the selected location. If
the point Code is associated with line work the point is connected
to the previous point with a line.
Point Code -
Specify a single code for all grid
points
Starting Point Number - Specify the point number to begin
numbering sequence with
Cell Size - Enter the size of the grid spacing
Point Within - Specify the radius for the program to
consider for the Elevation Method Snap setting
Elevation - Similar to above, specify the snap settings for
elevations within the radius specified.
Example: The above settings would set points at the lowest
elevation found within a 0.25 radius. (The drawing units are
considered ie. meters, feet)
