Brief Description of the Procedure for Creating Custom Linetypes

You can view and, if necessary, edit the content of GOST 2.303-68.lin file in any text editor that saves data in ASCII format:

A,20,-1.5,1,-1.5,1,-1.5

Lines that start with a semicolon (;) character are comments.

Description of a linetype consists of 2 lines: the first line contains the linetype name and a short description, the second line specifies the linetype outline.

*GOST2.303 5,Dash-dot thin ____ _ ____ _ ____ _ ____ _

A,20,-1.5,1,-1.5

An asterisk is placed before the linetype name. The name should be unique.

*GOST2.303 5

The linetype name is separated from a short description by a comma.

*GOST2.303 5,Dash-dot thin ____ _ ____ _ ____ _ ____ _

A brief description consists of a text part explaining the purpose of the linetype (for example, the explanation Dash-dot can be changed to the following: To draw center lines). The description often includes a sequence of text characters (dashes, spaces, dots, etc.) that visually resembles this line. The description can be up to 47 characters long. The description is optional and can be omitted. If there is no description, no comma is placed after the linetype name.

The second line containing the linetype description begins with the character A, which defines the type of alignment.

Further, separated by commas (without spaces), write the linetype elements that specify the line style.

A,20,-1.5,1,-1.5

As elements of the linetype outline, the following can be used:

·         zero – specifies a dot construction;

·         positive decimal numbers – specify the construction of dashes (a number value determines the dash length in drawing units);

·         negative decimal numbers – specify the construction of spaces (a number value determines the space length in drawing units);

·         text objects;

·         embedded shapes stored in form files.

Linetypes described by dashes, dots and spaces are called simple. The complex linetypes include the ones described by text objects and embedded shapes. Linetypes that include text objects and embedded shapes are used in utility network signs, in topographic symbols, and so on.

In the GOST 2.303-68.lin file the linestypes *GOST2.303 4, *GOST2.303 5, *GOST2.303 6 and *GOST2.303 9 are simple, the linetypes *GOST2.303 3 and *GOST2.303 8 are complex, because their descriptions use the embedded shapes WAVE and BREAK.

Alignment type A determines the condition according to which lines should begin and end with dashes, i.e. the value that determines the length of the first segment of the line should be greater than or equal to zero.

In order to better understand what alignment is and how it works, consider an example of drawing a line segment from point 1 to point 2 using Dash-Dot linetype. The program will construct a segment in such a way that it starts at point 1 and ends at point 2 with dashes. If necessary, the first and last dashes can be lengthened to meet the alignment condition. For a short segment, if it does not contain even one link long_dash-space-short_dash-space, the program will draw one dash (continuous line).

The linetype description line should not exceed 80 characters.

For each linetype it is possible to define no more than 12 elements.

In the linetype description, it is enough to specify one repeating fragment (link). For example, for the Dash-dot linetype such fragment is the link long_dash-space-short_dash-space.

The format for determining a simple linetype is:

A,Length1,Length2,Length2,…

Text objects are generally described in a complex linetype definition in the following format:

[”Text”,Style,Scale,Rotation_angle,Offset_X,Offset_Y]

The format for writing the embedded shape in the definition of a complex linetype:

[Name,File]

or

[Name,File,Scale,Rotation_angle,Absolute_rotation,Offset_X,Offset_Y]

Parameters:

Scale

The scale factor by which the height of the text style or the original height of the shape is multiplied.

The format of the entry in the linetype description:

S=value.

If the height of the text style or the initial height of the shape are equal to 0, then the specified value of the S = parameter is used as the height.

S=3, S=0.1, S=.1

Rotation angle

The angle of rotation of a text object or embedded shape relative to the line direction.

The format of the entry in the linetype description:

R=value.

It is allowed not to specify the parameter, in this case its value is assumed to be 0.

R=0, R=30, R=-90

Absolute rotation angle

The angle of rotation of a text object or embedded shape relative to the coordinate origin, i.e. all text objects or all shapes rotate the same regardless of their position relative to the line.

The format of the entry in the linetype description:

A=value.

It is allowed not to specify the parameter, in this case its value is assumed to be 0.

A=0, A=45, A=-30

Offset by X

The offset of a text object or embedded shape by X axis directed along the line.

The format of the entry in the linetype description:

X=value.

The parameter X=0 is set when describing a continuous line containing text objects or embedded shapes.

It is allowed not to specify the parameter, in this case its value is assumed to be 0.

The parameter S= does not affect the X offset.

X=5, X=-2.5, X=0.01

Offset by Y

The offset of a text object or embedded shape by Y axis perpendicular to the line.

The format of the entry in the linetype description:

Y=value.

The parameter Y=0 is set when describing a complex line containing text objects or embedded shapes without offset by Y.

It is allowed not to specify the parameter, in this case its value is assumed to be 0.

The parameter S= does not affect the Y offset.

Y=0.01, Y=-3.5, Y=7
