TPC provides a number of line types for you to use right out of the box. Plus, you can create your own line types.
Pattern lines are composed of a series of line segments and spaces. TPC includes standard pattern lines like Dot, Dash, DashDot and so forth.
Text lines include embedded text, as in ---< Utility >----. The embedded text reoccurs at some interval as the line is drawn.
Symbol lines include drawing objects like the stone wall or bike path objects in TPC’s object library.
Marker lines include character markers like ticks, slashes and Xs. You can space the markers at any interval, include any combination of line segments, spaces, and markers and even mix markers within the same line.
TPC includes dozens of predefined line types. You’ll find the most common pattern, text, symbol and marker lines predefined. To use one, just select it as the line type for your traverse or drawing object.
TPC’s predefined line types are included in the TpcLines.DAT file. This file is a self documenting, ASCII text file.
Many of the predefined line types come in varying sizes and lengths. For instance, the Dash_2 line is the same as the Dash line type, but the dashes are only half as long whereas the Dash_X2 has dashes twice as long.
TPC appends a _2 to the original line type to indicate that the pattern repeats twice as often. A _X2 appended to the line name indicates that the pattern takes twice as long to repeat.
If TPC has more than one type of line for something, it appends a number to the end. So Name, Name1 and Name2 would be three separate line types for Name.
Here is an example of multiple line types with multiple variations
Notice how heach line type (Fence Barb Wire, Fence Barb Wire2 and Fence Barb Wire3) include 3 variations of each line type name. This is typical for TPC's line types.
You can add your own line types to TPC by editing the UserLines.DAT file. You can also modify any of TPC’s predefined line types by re-defining it in the UserLines.dat file.
If you don't want to wade through line types you never use, you can edit the UserLine.dat file and begin any line with a minus sign '-'. Those line types will still be available to any drawings that reference them, but TPC will not include them in the pulldown list of line types. See Line Type Syntax for information on the format TPC uses to define line types.
TPC includes most of the predefined line types in AutoCAD. TPC replicates them for your use in TPC, and exports the line using AutoCAD’s own names when you write a DXF or DWG file.
You can include any line type in the legend by right clicking the line and choosing Add to Legend.
