This structure contains a line type definition.

Element Description

m_szLineName Changed in Version 2019.1

[MKI_LINENAME] Name of the line type, up to 63 characters.

m_szLineComment New in Version 2023.2

[MKI_COMMENTSHORT] Comment on the line type, up to 63 characters.

m_nLineNum

[__int32] Number of pairs of "line" and "hole". Valid range: 0 <= Value <= MKI_LINEPART_MAX / 2. If this value is 0, the resulting line is a solid line.

m_nLineMode Changed in Version 6.0

[__int32] Definition mode of the line type (see MKI_LINETYPE_*). Supported values are:

MKI_LINETYPE_STANDARD

MKI_LINETYPE_ABSOLUTE

MKI_LINETYPE_USELINE

MKI_LINETYPE_USEBLOCK

m_adLineData Changed in Version 2013.0

[double[]] Partial line length pairs. Each line length may be between 1e-10 and 1e10 inclusive. The first value of each pair defines a "line", the second value defines a "hole". This list must contain exactly two times the number of line lengths as stated by the value stored in m_nLineNum. The scale of these values (either 1/100 times line width or 1/100 mm) is defined by m_nLineMode.

m_pLineBlock New in Version 6.0

[MKI_LINEBLOCKDEF_PTR] Address of the attached block line type definition. If nullptr, no block line type is attached.

MKD Syntax

The section =LINE= contains up to MKI_LINE_MAX line type definitions.

A line type contains two types of pattern definitions:

Both types of line types can be combined. If both line type types are disabled, the line will be invisible.

The line type with the index 0 is named "*Standard" and is predefined by default as a solid line. This line type is valid throughout all drawings and libraries and does not occur in any MKD file.

Head of Section

=LINE=

TotalNum;

Entry for each Line Type Definition

LineName,LineIndex,

LineNum,LineMode,LineComment,

LineData[0],LineData[1] ... ,LineBlock;

End of Section

=END=;

If the section =LINE= does not exist, assume no line type to be defined (m_nTotalNum = 0).

Element Description

m_nTotalNum

[__int32] Number of line type definitions to follow. Valid range is 0 to MKI_LINE_MAX inclusive.

m_nLineIndex

[__int32] Index of the line type (1 to MKI_LINE_MAX). Each index may be assigned to one line type only, as this index is used internally to identify a line type.

m_cLineBlock New in Version 6.0

[MKI_LINEBLOCKDEF] This entry contains a complete block based line type definition. If no block based line type is used, this entry might contain only m_nBlockNum = 0 and m_nBlockMode = 0.

Example of a Line Type Definition

|Name,Index|

"Dash-dot-dot narrow DIN 15-G",4,

|Num,Mode,Comment|

3,0,"",

|Data|

4000,500,500,500,500,500;

This is the definition of the line type "Dash-dot-dot narrow DIN 15-G" having the index 4. It consists of three pairs of "line" and "hole", defined in 1/100 of the line's width. When drawing a 0.25 mm wide line using this line type, the result would be as follows:

 xxxxxxxx x x xxxxxxxx x x xxxxxxxx

    10   5×1.25  10   5×1.25  10 mm
