Export settings

Export settings

Use the BVBS Export dialog box to control the BVBS export settings.

For instructions on how to export to BVBS format, see Export to the BVBS format.

Parameters tab

Option

Description

Model objects to be exported

Select which reinforcing bars or meshes are exported.

  • Reinforcement of all cast units in the model

    Exports reinforcing bars or meshes in all cast units in the model. If there are cast units that do not have reinforcing bars or meshes, no empty files are created.

  • Reinforcement of selected cast units

    Exports reinforcing bars or meshes in the cast units you have selected in the model.

  • Selected reinforcement only

    Exports the reinforcing bars or meshes you have selected in the model. When you select this option, you can export only to a single file.

  • Reinforcement of all cast units in the model (totals by all positions)

    Exports reinforcing bars or meshes in all the cast units that have the same cast unit position as any of the selected cast unit positions.

    For example, if a cast unit with the cast unit position W-120 is selected, the reinforcing bars or meshes in all the cast units that have position W-120 are exported even though not all of them were selected.

Excluding reinforcement by filter

Exclude reinforcing bars or meshes by selecting any of the selection filters. Reinforcing bars or meshes that match the filter are excluded.

Drawing name source

In BVBS file each row/rebar has a data field for Drawing number of the respective drawing (drawing name) and Index of the respective drawing (drawing revision). With the option Drawing name source you can control how the values for these data fields will be set.

Cast_unit_position

Drawing Name

Drawing Mark

Drawing Title1

Drawing Title2

Drawing Title3

Fixed text : If you select this, enter the text in Fixed drawing name.

By selecting the option Fixed text you can enter the values in the dialog box and same ("fixed") values will be written for every exported rebar.

If any of the other options is selected, the drawing name and revision will be taken from the cast unit or cast unit drawing of the rebar.

Note that it depends on the receiving system of the BVBS file how important and for what purpose this data will be used. From Tekla Structures perspective, using this data field is not obligatory.

Fixed drawing name

Enter a text string to be used for the drawing in the export.

This option is available only when you have selected the option Fixed text in Drawing name source.

Rev

Drawing revision (index).

This option is available only when you have selected the option Fixed text in Drawing name source.

Single file

Export all BVBS information into one .abs file. Enter the file name in the box or click the ... button to browse for the file. If you do not enter a path, the file is saved in the model folder.

One file per each cast unit

Export each cast unit reinforcement content to its own file.

The files are created under the folder that you define in the Folder name box, or you can browse for the folder using the ... button.

Use the File naming template list to select how the created files are automatically named.

You can include revision into file name by selecting the Include revision into file name check box.

BVBS elements to be exported

Select which item types are exported. The options are:

2D reinforcement bars (BF2D)

3D reinforcement bars (BF3D)

Sprial reinforcement coils (BFWE)

Reinforcement meshes (BFMA)

Lattice girders (BFGT)

If you select Lattice girders (BFGT) , enter the class numbers used in the model for the lattice girder bars in the Class numbers for girder box. The lattice girder may contain two or three chord bars and one or two diagonal zig-zag bars. The lattice girder length and other attributes are taken from the main chord (usually top chord).

Advanced tab

Option

Description

Try to make meshes of rebars

Select whether the export tries to automatically form meshes of a single reinforcing bar or of a group reinforcing bars and export them as a mesh instead of separate 2D bars. The options are:

Yes, group rebars by class

Yes, group rebars by name

Yes, group rebars by grade

Yes, group rebars by UDA

In order to form a mesh the reinforcing bars need to belong to the same part, be straight, be on the same plane, and have equal filtering attribute values.

UDA name for grouping

If you selected the value Yes, group rebars by UDA for Try to make meshes of rebars , enter the UDA name for grouping.

Exporting of mesh bar data (@X..@Y..)

Use this option to control whether the detailed data on mesh bars is included in the exported data of the mesh. The appropriate option depends on the needs and capabilities of the receiving system. The data is needed if it will be used, for example, for mesh fabrication.

  • Custom and cut catalog meshes only

    Detailed bar data is included only for custom meshes and catalog meshes that have additional cuts, openings or skewed edges.

  • All meshes

    Detailed bar data is written for all meshes.

  • None meshes

    Detailed bar data is not written to any of the meshes.

Export stepped bars as separate items

By default the stepped group is exported as a single string with the stepping length defined in a certain data block.

If you select the value Yes for Exporting of mesh bar data (@X..@Y..) , all tapered reinforcing bar groups are exported as multiple separate reinforcing bar items even if they have regular spacing and could be exported as one single stepped reinforcing bar item.

Sort items

Use this option to define the order of the items in the output files. The options are:

No sorting

By diameter, smaller size first

By diameter, bigger size first

By position number

Private data block

With Private data block you can control whether the private data block is exported ( Export private data block ) and select the data items for this additional block. Data fields can be any report properties, user-defined attributes, or object properties.

Click the New button to add new predefined private data fields to the list. Enter information about the data item.

  • Name in list

    The text shown in the Private data block list.

  • Field identifier

    The field code which separates the individual data fields in the private data block. It can be any lower case letter. Typically, it is a good practice to use a different value for each data item but this is not required. The receiving system may also be able to read only certain data fields.

  • Property or UDA name

    The value defines which data will be inquired from the reinforcement object. Note that a non-existing property will be not exported.

  • Property data type

    The value has to match the actual selected property. The options are:

    Report property - Integer/Float/Text

    User-defined attribute - Integer/Float/Text

    Open APi object property

Checking tab

Option

Description

Check cutting length

Select whether you want to run an additional check for the Minimum cutting length and Maximum cutting length of the reinforcing bars.

When you select the Check cutting length check box, and the cutting length of the exported reinforcing bar is less than the minimum cutting length or greater than the maximum cutting length, a warning is written to the export log file.

The log file entry contains the ID of the reinforcing bar. You can locate the reinforcing bar in the model by selecting the appropriate row in the log file. Note that the reinforcing bar is still exported normally and only the additional warning is given.

Note that when the minimum/maximum cut length check is activated, the length of lattice girders is also checked. A warning is added in the log when the check fails. The length of the main chord defines the exported length of the lattice girder.
