Use the middle box to define the number of additional embeds.

Mirroring

  • Define the COG (center of gravity) for the selected parts, an assembly, or an assembly without steel parts. Assembly without steel parts takes concrete parts and miscellaneous parts into calculations.

  • Select whether embeds are mirrored.

    Mirroring is useful for asymmetric custom part embeds. You can mirror both in reference line direction and cross section direction.

  • Select whether both anchors are created, or only left or right anchor.

Lift.dat configuration file

You can use a configuration file to calculate the lifting capacities of lifting anchors.

Set Browse configuration file to Yes, and define the full path to the configuration file. The default file is lift.dat, located in the profil folder.

The lift.dat configuration file contains a list of all custom lifting anchors belonging to the default Tekla Structures installation. The anchors are sorted based on fabricator and type, component name and lifting capacity. You can add more custom components to the list in the configuration file. The file can be opened in any text editor, for example Notepad.

  • Type

    Groups where lifting anchors can be selected.

  • Type client

    Description of types.

  • Name CuCoPa

    Name of custom component part as listed in the Applications & components catalog.

  • Lift force (kg)

    Lifting capacity in kilograms.

  • Dir

    Direction. Component direction during creation of custom component part.

  • Attribute file

    Link to the configuration file.

The anchor type can be selected from the list. The first list option corresponds to the first type (1) in the lift.dat configuration file.

The last list option is All types and use preference list. This option searches from all groups. A preference can be defined in the Preference type list. Start with the highest preference group and separate the groups with a space.

Several fabricators have lifting anchors with the same lifting capacity, but with different anchor lengths. Use the order in the configuration file to define which anchor is selected. First found anchor with correct capacity = 1, second found anchor = 2, and so on.

Note:

If you have selected to use a custom part, ensure that the corresponding custom parts are available in the model. Names of the custom parts should not contain spaces, because they are not read from the lift.dat configuration file.

Show information message boxes

Define whether a message box containing the embed calculation results is shown. The message box shows the weight to be lifted up, the real lift-up weight including a safety factor, and the selected anchor.

The message box appears only if you have set Browse configuration file to Yes on the Placement tab.
