Defining materials, thickness, and width of flat bars in the Fltprops.inp file

Use the Fltprops.inp file to define the materials, thickness, and width of the flat bars that are shown for plates in drawings and reports.

The Fltprops.inp file is located in the \profil folder in one of the folders under the environment folder ..\ProgramData\Trimble\Tekla Structures\<version>\Environments\. The exact location might vary depending on your environment. In the default environment, Fltprops.inp is located in ..\ProgramData\Trimble\TeklaStructures\<version>\Environments\default\General\Shared.

Note:

Copy the Fltprops.inp file to a model, project or firm folder, then modify the file in the new location.

The first row in the file contains flat bar material definitions enclosed in quotes " " and without spaces, followed by plate thicknesses. If you do not define a material, you can use all materials for all flat bars. The rows after that define the widths of available flat bars.

The units are millimeters.

Example

Fltprops.inp contains the following data:

5,6,"S235",8,10,"S275J0",10,15
40,45
50,55
60,65
70,75
100,110
200,220

With this data, Tekla Structures shows the following plates as flat bars in drawings and reports:


Plate	Material
5x40, 5x45, 6x50, 6x55	All materials
8x60, 8x65, 10x70, 10x75	S235
10x100, 10x110, 15x200, 15x220	S275J0

Set advanced options related to plate work in the Advanced options dialog box as required:

XS_USE_FLAT_DESIGNATION: Tekla Structures uses flat bar designation, which means that it shows plates as the equivalent flat bars for manufacturing.

XS_FLAT_PREFIX: The flat bars get the prefix that is set as the value for this advanced option.

XS_FLAT_TOLERANCE: Tekla Structures uses this value to check plate width to determine whether to convert it to a flat bar.

XS_FLAT_THICKNESS_TOLERANCE: Tekla Structures uses this value to check plate thickness to determine whether to convert it to a flat bar.

XS_CHECK_FLAT_LENGTH_ALSO: When this advanced option is set to TRUE, Tekla Structures checks the plate length and plate width, and then compares those with the possible dimensions for flat bars in fltprops.inp.
