Example: Base point use in Layout manager

This example shows different model views that contain a layout pointpoint that can be exported to a layout device

Layout point can be a reference 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.

  1. Create a control point in File > Project properties > Base points.

  2. 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 viewview that is represented in the modeling mode

    Model view is available also in the drawing mode and it is represented in its own window.


    • 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 pointpoint in a model that is used to define a starting point in surveying and that is used as an anchor point in coordinate and height transformations

      A Tekla Structures project can have several base points but only one of them can be the project base point.

      Base points allow the use of another coordinate system needed for interoperability and collaboration. Base points can also be used in drawings, and in reports and templates. Model origin is the default base point in Tekla Structures.

      Base points are also called control points.

      that you created.
    • The red cone is the layout point, in the image framed with a yellow square.
    • The green box is the model originglobal coordinate system point of origin used for the model

      Model origin is the default project base point.

      at the gridmodeling aid that represents a three-dimensional complex of intersecting grid planes or intersecting grid planes and curved grid surfaces

      The grid is defined by coordinates in 3D space. It is shown two-dimensionally on the view plane by dash-and-dot lines. A grid can be rectangular or radial.

      It is possible to have more than one grid in a model. For example, a large-scale grid for the entire structure, and smaller grids for some detailed sections.

      It is also possible to show grids and grid line labels in drawings, and to modify how they are shown in the drawings.

      intersection A-1.
  3. 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.

  4. 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.

  5. 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.
