Merged part marks

Merged part marks

A merged part markmark that includes a set of selected property elements related to a part

Part marks are used for identifying constructions, for giving information about welding, for giving information about assemblies to a workshop, for giving information about how parts should be connected to each other, and for creating bills of quantities, for example.

In the US, the term piece mark is used to refer to position number.

means that you have only one part mark for similar parts in a drawing, instead of a separate mark for each of the parts. Merged part marks indicate the number of included parts, and contain the defined part mark contents, and the near side and far side information. The marks are merged only in X direction of the main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

(1) Main part can be an assembly main part or a cast unit main part.

(2) input part that the user selects first when creating a component

(2) Connections and details always have a component main part.


Tekla Structures merges marks for visible parts in drawings if:

  • The secondary parts are welded or bolted to the same main part.

  • The parts are on the same line.

  • Distances between the parts are equal.

  • The parts have the same part positionposition number that is assigned to a part


  • Distance between parts is not more than what is set for the advanced option XS_​PART_​MERGE_​MAX_​DISTANCE.

  • There are at least as many parts in the array as it has been set for the advanced option XS_​MIN_​MERGE_​PART_​COUNT.


  • Part marks can be merged only on view and drawing level. It is not possible to merge or split part marks manually.

  • You cannot merge part marks (assembly marks) that are not part of the same assembly.

  • Tekla Structures does not merge neighbor partpart that is close to a part that the drawing is made for but that is not in the same assembly or cast unit

    The representation of neighbor parts is usually different from that of the part.

    Neighbor parts can be used as reference in dimensioning.


Advanced optionssettings used to customize Tekla Structures for specific companies, standards, users, or user groups

In Tekla Structures, advanced options are settings that are used, for example, in a specific project or geographical area, or by a specific company.

In Tekla Structures, advanced options usually begin with the initials XS and are followed by the name of the function, for example XS_BACKGROUND_COLOR.

in merging marks

In merging part marks, you may find the following advanced options useful:








In the example below, the part marks are merged in X direction of the HEA300 beam (main part).

In the example below, the leftmost part marks are not merged, because they are too far from each other.

In the example below, the marks in the Y direction are not merged, because the marks are merged only in X direction (which in this example is horizontal).
