You can change the properties of the hatch patterns for each surface treatment type separately.
The properties of the hatch patterns are defined in the surfacing.htc file, located by default in ..\Tekla Structures\<version>\environments\common\system. In addition to this file, the surface treatment code file product_finishes.dat is needed. It is located in the same folder.
If you create your own surface treatment hatch patterns in your company, you can store surfacing.htc and product_finishes.dat in the firm folder defined by the advanced option XS_FIRM.
When you edit a schema file, you must reopen the model to apply the changes.
This is the abbreviation used in drawings and reports, for example, MF for Magnesium Float. The product_finishes.dat file contains a full list of surface treatment codes.
You can check the hatch pattern names and related hatch patterns by going to the Fill tab in Part properties, selecting a hatch pattern from the Type list and clicking the ... button next to the list. The selected hatch pattern is marked with a red frame.
Scale is a numeric value that Tekla Structures uses to scale hatches.
120= Special (use this color for gray shade)
The hatch color defines the line width for the printer. If you do not define a color for a hatch in the surfacing.htc file, Tekla Structures uses the color defined on the Appearance tab in surface treatment properties. The Visible lines color and type is used for the front of the surface treatment, and the Hidden lines for the back.
