Lines

ntx_type: ntx_compacted_line

NTX compacted line features represent linear features and may be either 2D or 3D. Compacted line features may have the following attributes:

Attribute Name	Contents
ntx_scale	The denominator of the largest scale for which the data is valid. A value of zero means the scale indicator is undefined. Range: signed 32-bit integer Default: 0
ntx_weight	The line weight of the object, in steps of 0.001 inches at map scale. A positive value indicates that a rectangular slit should be used to plot the line. A negative value indicates that a round dot should be used to plot the line. Range: signed 32-bit integer Default: 0
ntx_X_resolution ntx_Y_resolution ntx_Z_resolution	X, Y, and Z resolution factors may be specified, to be used instead of global XRES, YRES, and ZRES settings. If you wish to represent very precise survey data but you also wish to compact less precise line data, you would have to define a resolution factor to essentially degrade the resolution of the lines. Failing to do so could lead to poor data compaction. Range: signed 32-bit integer Default: 1
ntx_smooth	The smoothing factor is used to define the amount of smoothing that may be applied to the data if it is plotted. A value of zero means that the data would be plotted exactly as defined. Range: signed 32-bit integer Default: 0

ntx_type: ntx_ptp_line

NTX point-to-point line features represent linear features and may be either 2D or 3D. These features represent both code 3 (simple) and code 4 (dashed) lines. Code 3 lines simply have their coordinates on the feature’s geometry. Code 4 lines have each dash as a two-point line in an aggregate on the feature’s geometry. When writing these features, an aggregate geometry will result in a code 4 record, otherwise it will output a code 3. Any pieces in the aggregate that are not two-point lines will be ignored. The order of the two-point segments in the aggregate reflect the order of the dashes in the record of the NTX file. Point-to-point line features may have the following attributes:

Attribute Name	Contents
ntx_scale	The denominator of the largest scale for which the data is valid. A value of zero means the scale indicator is undefined. Range: signed 32-bit integer Default: 0
ntx_weight	The line weight of the object, in steps of 0.001 inches at map scale. A positive value indicates that a rectangular slit should be used to plot the line. A negative value indicates that a round dot should be used to plot the line. Range: signed 32-bit integer Default: 0
