Environment

Not environment-specific

Rebar end symbol is an extension which with rebar couplers and end anchors / coupler can be shown as symbols in drawing views.

Why is this extension needed?

Couplers / end anchors are shown in drawings as parts by default. If user has wanted to show only some bars in a (e.g. bar in the middle) group he/she has needed to select all parts and manually hide these unwanted coupler / end anchor part. This workflow has been rather time consuming and Rebar end symbol extension now enhances it.
Using custom locations in rebar presentation has not been possible since the coupler / anchor parts are always drawn at exact location which normally is away from actual rebar presentation in drawing view. Rebar end symbol displays couplers / end anchors wherever attached rebars are visible in drawings.
User hasn't been able to customize how the couplers / end anchors are shown in drawings, but now that is possible.

How to locate?

'Rebar End Symbol' extension package is available in Tekla Warehouse. When it has been installed, the tool can be found listed under custom presentation tab of drawing reinforcement properties dialog.

How to use?

Select 'Rebar End Symbol' presentation as shown in the above message. Typical output is as below:

Rebar end symbol works based on rebar UDAs and these UDAs are controlled by Rebar Coupler and Anchor Tools.

How to customize?

You can customize how the symbols for couplers and end anchors are shown by editing the symbols and their mappings.
- The mapping is handled in the RebarCoupler.Symbols.dat file, located by default in ..\ProgramData\Tekla Structures\<version>\environments\common\system. The file can be placed under the model folder or under any of the common system folders defined by the advanced options XS_PROJECT , XS_FIRM , and XS_SYSTEM. For instructions on how to control the mapping, see the RebarCoupler.Symbols.dat file.
You can give both the symbol file name and symbol number in the configuration file RebarCoupler.Symbols.dat. If the symbol file name is not given, the default file ( CouplerSymbols.sym ) will be used. For more details, see sample files included in the environments.
You can create your own symbols that are drawn at the reinforcing bar ends.
- All symbols to be used are in the symbol file CouplerSymbols.sym , located by default in ..\ProgramData\Tekla Structures\<version>\environments\common\symbols. You can create and add new symbols in Symbol Editor.

Typical record in RebarCoupler.Symbols.dat as below.

The above highlighted records, each column represents the following attributes.

1st value - the value stored in rebar UDA (METHOD_START / METHOD_END) as per above file image.
2nd value - the value stored in rebar UDA (TYPE_START / TYPE_END) as per above file image.
3rd value - the value stored in rebar UDA (CODE_START / CODE_END) as per above file image.
4th value - The symbol file name without extension
5th value - Symbol index reference in symbol file.

Note: If the UDA ends with _S or _L (METHOD_S / METHOD_L) then the symbols are assigned based on the short and long legs of the rebar.

Example 1:

Ex: 2;0;24;CouplerSymbols;192 and it matches with start of the rebar UDA
2;0;*;CouplerSymbols;96 and it matches with end of the rebar UDA since 55 code is not exist in records however '*' can take any value.

The drawing presentation as below for start of rebar (short leg) and end of rebar (longer length).

Example 2:

Ex: 3;0;*;CouplerSymbols;144 and it matches with start of the rebar UDA (value 3;0;1)
3;0;2;CouplerSymbols;31 and it matches with end of the rebar UDA (3;0;2) however as per current procedure it picks the record 3;0;* since it appears first and it rakes all code values. To avoid such issue keep the records at bottom which contains '*'.

Known limitations

Symbols are shown only when couplers / end anchors are connected to a rebar leg which is parallel to drawing view.
Extension is not applicable to show end anchor / coupler in 3D views.
The symbols are picked first match record from RebarCoupler.Symbols.dat file.
