code. The code identifies the gridmodeling aid that represents a three-dimensional complex of horizontal and vertical planes

In Tekla Structures, grids are used as an aid in locating objects in a model. The grid is shown on the view plane by dash-and-dot lines. It is also possible to show grids and grid line labels in drawings, and to modify grid properties in the drawings.

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.

position. The position of the objects is calculated based on the closest grid.
















The position code consists of grid linesingle line that visualizes a single grid plane on a view plane

labels in the x and y directions (alternatively in the z direction). If an assembly begins or ends outside the first or last grid line, a < or > character is included in the position code. For example, if an assembly begins outside the A grid line, this field shows:


If an assembly is completely within a tolerance distance (by default 500 mm) of grid line A, the position code is the label of that grid line: A.

If the assembly is partially or entirely outside the tolerance distance, the code is a combination of grid labels: A-B.

To change the default tolerance distance, set the advanced option XS_ASSEMBLY_POSITION_CODE_TOLERANCE=750 (for example).

To include the Z orientation in the code, set the advanced option XS_ASSEMBLY_POSITION_CODE_3D to TRUE. The code would be similar to: <A-B/1-2/1-+1000

Tekla Structures selects the grid to use as follows:

  1. Tekla Structures checks the location of the assembly.

  2. If it is located inside several grids, Tekla Structures checks whether the assembly is parallel to grid lines or the plane.

  3. If there are several parallel grids, Tekla Structures selects the closest.
