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 number 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 attribute to which you assign the sequence numbers.

Limitations

Sequencer does not work for objects that are inside 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 (UDA). 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 name 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 pane.
  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.
