Example: Base point use in Layout manager
This example shows different model views that contain a layout point, control point, and civil origin in the model. The civil origin is the datum point, or the fundamental benchmark point of the national land survey network.
-
Create a control point in
File > Project properties > Base points.
-
Create a layout point by using the
Layout Point tool, and add the layout point to the model.
The image below shows the point locations in a 3D model view.
- The green point in the bottom-left corner is the civil origin.
Note that the East coordinate and North coordinate are not in scale here.
- The blue point is the control point, that is, the base point that you created.
- The red cone is the layout point, in the image framed with a yellow square.
- The green box is the model origin at the grid intersection A-1.
- The green point in the bottom-left corner is the civil origin.
-
In
Layout manager, add the layout point to a
group. Select the base point that you created,
Control point 1, to be used as the
Group local coordinate system of the group.
-
Check the coordinates of the layout point.
- Location in the model: the distance to the model origin.
- Location in the group: the distance to the base point selected for the layout point group.
- East, North, Elevation: the distance to the civil origin.
The images below show different views and measurements of the points in the model.

-
Export the layout point.
The X, Y and Z coordinates in the export dialog box are the East, North, Elevation (X, Y, Z) coordinates that you can view in Layout manager point properties. These coordinates are exported.
