Graphic Line Types |

Line types can be defined in T-FLEX CAD using one of the following methods:
1.Using a *.lin-file. This is the AutoCAD line types description format. So, if a desired line type is not available, it can be created by the user or copied from AutoCAD system, if you have AutoCAD installed. Name and location of the *.lin-file are set in system options (Options > Files > Line Type Files). The tcad.lin file located in the T-FLEX CAD installation folder is used by default (if T-FLEX CAD is installed in default folder, then the full path to the file is C:/Program Files/T‑FLEX Parametric CAD 17/Program/tcad.lin). The instructions on creating a custom line type using this method of description can be found in the AutoCAD documentation.
2.Using the specline.def file located in the T-FLEX CAD installation folder (if T-FLEX CAD is installed in default folder, then the full path to the file is C:/Program Files/T‑FLEX Parametric CAD 17/Program/specline.def). This file describes line types using links to types described in the *.lin-file (see above), but additionally allows to associate with a line type certain arrows or other symbols displayed at line's starting and ending points. By default, the file contains the following entries:
Thin THIN 0 0
Continuous CONTINUOUS 0 0
Center CENTER 28 28
Hidden HIDDEN 0 0
Each string of the file describes a particular line type and contains four parameters separated by spaces:
▪the name of the type to be displayed in T-FLEX CAD in the line type selection drop-down list;
▪the name of the type in the *.lin-file (see above);
▪the identifier of the starting arrow/symbol;
▪the identifier of the ending arrow/symbol.
Identifiers of arrows/symbols correspond to their order numbers in arrow selection drop-down list displayed in T-FLEX CAD.
3.The first parameter is a comment, the second is the line name (this name is used for identifying the line in the line descriptor file), the third and the fourth parameters are the Ids of the start and end symbols (per the enumeration in the endings list).
4.Using custom patterns stored in *.grb-files. A custom pattern is a T-FLEX CAD drawing creating in compliance with special rules described in the Custom Graphic Line Patterns section. The file should be put into the LinePatterns folder within the T-FLEX CAD installation folder (if T-FLEX CAD is installed in default folder, then the full path is C:/Program Files/T‑FLEX Parametric CAD 17/Program/LinePatterns).
