ACN Sequencer

Contents

This tool is used to assign Assembly Control Numbers (ACNuser-defined attribute of an assembly or a cast unit that identifies the assembly or cast unit main part

A control number does not affect numbering.

Control numbers are running numbers.

Purpose and description

This tool is used as a helping tool for 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.

model objects. The ACN can be used for example to store unique identification information to be used in logistics or building erection planning. The ACN information can be put to the preliminary structural parts. If preliminary parts are deleted from the model and replaced by copying fully detailed parts, the GUID numbers are changed, but ACN can be maintained manually so that the ACN numbers remain unchanged during the whole modelling process. The ACN number can be stored in 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.

of the assembly or in the assembly/cast unit.

Using ACN Sequencer

To be able to use this tool you need to set the start numberfirst number of a numbering series

and the step value. All selected Tekla Structures parts are numbered after pressing the Start numbering button.

User can select if the chosen number is stored in the main part of the assembly or in the assembly/cast unit depending on the selection chosen in the ‘SaveTo’ option.

While numbering the ACN Sequencertool that is used for creating named sequences for parts and assigning sequence numbers to the parts

Sequencer is used for defining erection sequences, for example.

user interface is locked. To finish the numbering or edit user interface options you need to use Tekla Structures Interrupt command (mouse right click > Interrupt or ESC button).

If Notify Duplicates is checked, there may be a delay after pressing of the Start numbering button before the object picking is started. That is because the applicationpart of Tekla Structures functionality that is developed in order to extend the capability of Tekla Structures but that is not included in the Tekla Structures installation

needs to search from the whole model all ACN values that have already been used.

In the options group you can allow the tool to overwrite existing ACNs or notify duplicates that will warn you if you are trying to add an ACN that already exists in the model.

By pressing the Remove numbers button you can pick parts from the model from which you want the ACN number to be removed.

You can press the Check for duplicates button to verify that your model does not include duplicate ACN values. If an object has ACN=1 in MainPart and another object ACN =1 in Assembly this is considered a duplicate.

This tool allows you to blink the model objects that have duplicates which makes it easier to find them in the model. It is recommended to use Ctrl+5 and Shift+5 keyboard shortcuts to make the 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.

transparent. Then the blinking objects change into non-transparent while blinking that makes them easy to find. To blink the model objects you need to select the option Blink the assemblies in the model and double click one of the rows of the ACN Duplicates table. To stop blinking simply press the stop blinking button or close the dialog.
