Topology Variables

Topology variables store properties for topologies, which are created by tpm_mntbuild and the topology analysys functions, tpm_ana[xx].

Topology variables are a subset of the configuration variables data structure.

BUILD_TOL	Tolerance for topology building, buffering, and other processes (positive real). Default = 0.01
CNTR_COLOR	Color for new centroids, an AutoCAD color index (integer). Negative integer = Current color Default = -1 See Color Index Colors.
CNTR_LAYER	Layer name for new centroids (string). nil = Current layer Default = ""
CNTR_TYPE	Entity type of new centroids (integer). 1 = Point (default) 2 = Block
CNTR_BLOCK	Block name for new centroids (string). Default = ""
CREATE_CNTR	Flag for centroids generation (integer). 1 = Generate (default) 0 = Do not generate
CREATE_MARKERS	Whether errors should be marked with persistent markers as drawn by tpm_cleanerrormark (integer). 0 = Do not mark (default) 1 = Mark Marker shapes are set by MARKER_HEIGHT and the [XX]_MARKER cleanup variables.
CREATE_NODE	Flag for nodes generation (integer). 1 = Generate (default) 0 = Do not generate
CREATE_VIEW	Whether errors should be marked with temporary markers as drawn by tpm_cleanerrordraw 0 = Do not mark 1 = Mark (default)
DEF_OFFSET	Default offset (real). Use when offset value cannot be calculated for an object, for example, if the object lacks necessary object data. Default = 1.0
DUPLICATE_CENTROID_COLOR	Marker color for duplicate centroid errors, an AutoCAD color index (integer). Default = 1 (red) See Color Index Colors.
DUPLICATE_CENTROID_MARKER	Marker shape for duplicate centroid errors (integer). See Marker Shapes. Default = 4 (square)
IGNORE_INCOMPLETE_AREA	What to do if links are encountered that do not belong to any polygon (integer). 1 = Ignore them 0 = Cancel topology creation process (default)
INCOMPLETE_AREA_COLOR	Marker color for incomplete area errors, an AutoCAD color index (integer). Default = 2 (yellow) See Color Index Colors.
INCOMPLETE_AREA_MARKER	Marker shape for incomplete area errors (integer). See Marker Shapes. Default = 2 (triangle)
INTERSECTION_COLOR	Marker color for intersection errors, an AutoCAD color index (integer). Default = 3 (green) See Color Index Colors.
INTERSECTION_MARKER	Marker shape for intersection errors (integer). See Marker Shapes. Default = 1 (octagon)
MISSING_CENTROID_COLOR	Marker color for missing centroid errors, an AutoCAD color index (integer). Default = 4 (cyan) See Color Index Colors.
MISSING_CENTROID_MARKER	Marker shape for missing centroid errors (integer). See Marker Shapes. Default = 3 (rhombus)
NODE_BLOCK	Block name for new nodes (string). Default = ""
NODE_COLOR	Color for new nodes, an AutoCAD color index (integer): Negative integer = The current color Default = -1 See Color Index Colors.
NODE_LAYER	Layer name for new nodes (string): nil The current layer Default = ""
NODE_TYPE	Entity type of new nodes (integer): 1 Point (default) 2 Block
STOP_AT_MISSING_CNTR	What to do if a polygon has no centroid (integer): 0 Create a centroid (default) 1 Cancel topology creation process
STOP_AT_MULTIPLE_CNTR	What to do if a polygon has more than one centroid (integer): 0 Designate one centroid 1 Cancel topology creation process (default)
