Control number order
When you assign control numbers, you must define in what order to assign them. The order is based on the location of each part on the global coordinate systemcoordinate system that reflects the entire space of a model
A green cube represents the global coordinate system and lies at the global point of origin in the 3D view.
The options are:
With positive directions (X, Y, and Z), the parts with the lowest coordinate value are numbered first. With negative directions (-X, -Y, and -Z), the parts with the highest coordinate value are numbered first.
For example, if the first direction is X, the second direction is Y, and the third direction is Z, numberingprocess of assigning position numbers to parts, cast units, assemblies, or reinforcement
In Tekla Structures, the position numbers assigned in the numbering are shown in marks and templates, for example.
starts from the parts that have the lowest x coordinate value. If multiple parts have the same x coordinate, also their y coordinates are compared. If multiple parts have the same x and y coordinates, also their z coordinates are compared.
In the following example, the first direction is X and the second direction is Y. The numbers 1–8 indicate the control numbers.
