Line Types





TPC provides a number of line types for you to use right out of the box. Plus, you can create your own line types.


Line Types (4:04) - Learn how to use and edit TPC's line types and share them with CAD.

General Types

All of TPC's line types are one of these general types.

Pattern Lines

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

Text lines include embedded text, as in ---< Utility >----. The embedded text reoccurs at some interval as the line is drawn.

Symbol Lines

Symbol lines include drawing objects like the stone wall or bike path objects in TPC’s object library.

Marker Lines

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.

Predefined Line Types

TPC includes almost 200 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 Line Type Naming Convention

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.

See Line Type Names.

Adding Your Own Line Types

You can add your own line types to TPC by adding them to the UserLines.dat file.

See Adding Line Types.

Editing Existing Line Types

You can also modify any of TPC’s predefined line types by re-defining it in the UserLines.dat file.

See Editing Line Types.

if you are displaying line type categories, you can also hide entire categories of line types.

See Editing Categories.

Hiding Line Types You Never Use

If you don't want to wade through line types you never use, you can edit the UserLines.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 Hiding Line Types.

Predefined AutoCAD Line Types

TPC includes many 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.

See Using Predefined AutoCAD Line Types.

How the Legend Draws Line Types

You can include any line type in the legend by right clicking the line and choosing Add to Legend.

See Adding Lines to a Legend.

Saving Modified Line Types with Drawings

When you save a drawing with one or more modified line types, TPC has to store the syntax of those lines with the drawing to ensure that it can reproduce the drawing at a later date, even if that modified line type is no longer available in the UserLines.dat file. It does this by saving the same definition for that line type found in the UserLines.dat file.

Modifying a Modified Line Type

If you use a modified line type in a drawing, then modify the definition of that line type later on in your UserLines.dat file, TPC will retain the original line type definition in that drawing because the line type definition got saved with the drawing. For that drawing to use the newly modified line type, any lines using that line type must be set to a different line type, the survey must be saved and reopened to clear the line type definition, then those lines can reset to the desired line type.

Line Type Categories

TPC gives you the option of grouping your line types into categories, then expanding one category at a time to select a line type. 

See Line Type Categories.
