Tekla Structures – Surface treatment

surface

treatments

The overlapping area is recognized in reports: only the topmost (visible) surface treatment is calculated.

1. Click Detailing > Properties > Surface Treatment… to open the Surface Treatment Properties dialog box:

3.     In the Surface treatment name list box, select the specific surface treatment.

4.     Click the Select… button against Material to select a material from the catalog.

5.     Enter the Thickness of the surface treatment.

6.     Set the Color to use to display the surface treatment in rendered views.

7.     In the At depth list box, select the location of the surface treatment. The options are Middle, Front, and Behind.

8.     Click Apply or OK to save the surface treatment properties. To define the properties of a tiled surface treatment, continue as follows:

1.     On the Attributes tab, select Tile surface from the Type list box.

2.     On the Pattern tab, select the pattern from the Pattern type list box.

3.     The Definition table lists the properties of the pattern type.

When you redefine the properties of a part (e.g. you change the size of a part), Tekla Structures automatically modifies the surface treatment to fit the part.

To define your own surface treatment properties to use in reports and drawings, click the User-defined attributes… button and go to the Parameters tab. Adding properties in the online help explains how to add user-defined properties.

Tiled surface treatment options are based on repeating tile patterns that are stored in XML format. For more information creating tile patterns

XML file                       To define your own tile patterns:

1.    Open the TilePatternCatalog.xml file using any text editor. The file is located in the

..TeklaStructures\*version*\environments\*your_environment*\s ystem folder.

2.     Add a new <TilePattern> element to the file. A <TilePattern> element must have <HOffset> and <VOffset> elements and at least one <Tile> element. Other elements are optional. You may find it easier to copy one of the existing elements, then change it suit your needs.

The TilePatternCatalog.xml file can contain the following elements:

4.    Save the TilePatternCatalog.xml file.

Adding surface treatment to parts with cuts and recesses

To force Tekla Structures to consider openings and recesses in parts when adding surface treatment, select the Cut by father part cuts checkbox in the Surface Treatment Properties dialog box:

to cut faces

1.

2. 3. 4.

Click Detailing > Create Surface Treatment, and then click either To Part Face or To

Selected Area on Part Face.

Pick the origin of the surface treatment.

Pick the direction.

Select the cut face on which to apply the surface treatment:

2.     Set the cut thickness for the variable XS_POLYGON_CUT_EXTRA_THICKNESS. The default value is 5.0 mm.

Adding surface treatment to chamfered parts

Take these things into account when adding surface treatment to chamfered parts:

•      Surface treatment does not work on sketched profiles with chamfers.

•      Add surface treatment before chamfering the part. If surface treatment is applied to a chamfered part, the surface treatment chamfer cannot be modified later on.

•      The chamfers for the main part and surface treatment are separate. Modifying the main part chamfer does not affect the surface treatment chamfer.

•      The orientation of unsymmetric chamfers depends on the face where it was created (such as top, bottom, left, or right). To change the orientation of an unsymmetric chamfer, you must swap the chamfer’s x and y values.

Creating and editing surface treatment options

To create new options in the Surface treatment name list box in the Surface treatment properties dialog box, or to edit existing names, edit the product_finishes.dat file, located in the ..environments\*your_environment*\system folder.

// ————————-

//

// Type : Type of surfacing

//                                       1 = concrete finish

//                                       2 = special mix

//                                       3 = tile surface

//                                       4 = steel finishes

The remaining sections define the options for each type of surface treatment. This is where you can edit existing options, or add rows to define new options:

// WET FINISH

// ———-

1 MF 1 SMF 1 WT

•      1 is the surface treatment type (concrete finish)

•      MF is the code for the surface treatment option

•      “Magnesium Float” is the full name of the surface treatment option (remember to enclose the name in double quotes ” “)

Here is how this option appears in the dialog box:

You can include the following surface treatment specific fields in report templates:
