Sequencer

Sequencer

Use the Sequencer tool to create sequences and to assign incremental numbers to parts.

You can define several sequences for different purposes, and a part can belong to several sequences at the same time. For example, you can create erection sequences to define the order in which to erect parts.

Sequencer works by assigning a sequence numberincremental number of an individual part that belongs to a sequence of parts

to a user-defined attribute (UDA) of a part. If you want to view and modify the sequence numbers afterwards, you must first create a new user-defined attributeobject property created by the user in order to widen the range of predefined object properties

User-defined attributes are used when the predefined object properties are not sufficient but more properties are needed. For example, comment, locked, and erection status are user-defined attributes.

to which you assign the sequence numbers.

Limitations

Sequencer does not work for objects that are inside a reference modelmodel which the designer can use as an aid when building another model

A reference model is created in Tekla Structures or in other software and can be inserted to Tekla Structures. The reference model appears together with the model but it is not modified by Tekla Structures. The user can snap to reference model points.

For example, an architectural model, a plant design model, or a heating, ventilating, and air-conditioning (HVAC) model can be a reference model.

.

Create a sequence

  1. First, create a user-defined attribute (UDA) to which you assign sequence numbers.

    In the objects.inp file, search for the Part attributes section to add a new user-defined attribute (UDAobject property created by the user in order to widen the range of predefined object properties

    User-defined attributes are used when the predefined object properties are not sufficient but more properties are needed. For example, comment, locked, and erection status are user-defined attributes.

    ). The value_type must be integer , and the field_format must be %d.

    For example:

    attribute("SEQUENCE_1", "Sequence 1", integer, "%d", no, none, "0.0", "0.0")

  2. In Tekla Structures , go to the Manage tab and click Sequencer.

    The Sequencer Properties dialog box opens.

  3. In Sequence name , enter the name of the sequence. The sequence nameuser-defined attribute name that indicates a sequence of parts

    has to be exactly the same as the name of the UDA defined in the objects.inp file.

    For example, SEQUENCE_1.

  4. Click Apply.
  5. Select the parts you want to include in the sequence.

    The first part gets the sequence number 1, the second part number 2, and so on.

    The Sequencer Properties dialog box lists the sequences that you have entered in the Sequence name box. Max number shows the highest number that is in use in the selected sequence.

    If you select a part that has already been included in the sequence, Tekla Structures asks if you want to override the existing number. If you click Yes , Tekla Structures gives the next available number to the part.

  6. To finish adding parts to the sequence, right-click and select Interrupt or press Esc.

Add parts to a sequence

You can add new parts at the end of an existing sequence. If you want to add parts in the middle of the sequence, you must redefine the whole sequence.

  1. On the Manage tab, click Sequencer.
  2. Select a sequence name from the list.
  3. Click OK or Apply.
  4. Select the parts you want to add to the sequence.
  5. To finish adding parts to the sequence, right-click and select Interrupt or press Esc.

Check the sequence of a part

You can check the sequence name and number of a part by using the Inquire object command.

  1. On the ribbon, click Inquire object .
  2. Select a part.

    Tekla Structures displays the properties of the part. The sequence name and number are displayed under More. For example:

Modify the sequence number of a part

You can modify the sequence number that has been assigned to a user-defined attribute (UDA) of a part.

  1. Double-click a part to open the part properties in the property panecontrol element in Tekla Structures user interface in the form of a side pane window

    The property pane can be used to show and modify the properties of model objects.

    .

  2. Click More.

    The current sequence number is displayed next to the UDA to which you assigned the sequence number. For example, Sequence 1.

  3. Modify the sequence number.
  4. Click Modify.

Delete a sequence

  1. On the Manage tab, click Sequencer.
  2. Select a sequence name from the list.
  3. Click Delete and then click Yes.
