Step Detail

2.3.3 - Display Options with C3D Point Groups

Step Description:

In order to utilize the extended properties embedded in the LandXML file to create Civil 3D Point Groups you must transfer Survey Point Groups from the Survey Toolspace to the C3D Prospector. Utilizing the Civil 3D Point Groups provides more tools to analyze the data, than the survey database.

• Begin by inserting the appropriate Point Group from the Survey Toolspace into the drawing (procedure covered in previous step).

NOTE: If you would like to view all the points from the import event you would simply right-click Survey Point Groups > Insert into drawing. This will insert all points from the import event.

• Select the Prospector tab in the Toolspace. In the Prospector tab under Point Groups the Point Group will now be listed.

NOTE: The C3D Prospector provides more tools to organize and analyze Point Groups than the Survey Toolspace allows.

To modify the display styles of the C3D Point Groups

• Right-click [Point Group name] > Properties > Information tab.

Select Properties Image

• Under Default styles choose correct Point style and Point label style if needed.

Filtering point groups in the C3D workspace.

• Right-click Point Group > Properties.
• In the Properties dialog utilize the various tools (tabs) to filter what is displayed in the workspace.

One example of filtering and editing points in the C3D workspace is as follows:

• In Toolspace > Prospector tab > expand Point Groups > right-click 15502 > Properties

Select Point Group Properties Image


NOTE: In this case point group 15502 was created with all points from the import data. Also if there is no point code description the point will not be displayed by default.

• In the Point Group Properties dialog > Information tab > change Point style to none & change Point label style to none.

NOTE: The property drop down list contains all the properties provided in the survey database along with the additional LandXML properties. In this example property "Point.CgPoint.DTMAttribute" contains the ground or feature value.

• Select Apply > OK

The Properties for _No Points may also have to be modified in order to get the correct display. To do this right click _No Points > Properties > Information tab > change Point style to none & change Point label style to none
This process will display the points in the C3D workspace that have a description and the ground attribute.

• By right-clicking Point Groups > Properties the Point Groups dialog will be displayed
