v_attr_val |
Use these ERF variables when a feature is assigned some
attribute (any attribute except for
.pad_usage) that requires it to be processed by a specific method
(such as, to maintain different spacing requirements). The following lines
represent an example based on the .pad_usage
attribute. Maintain distance from features with a special attribute
set: v_keep_away_from_attr
= yes Maintain this distance: v_keep_away_attr_dist
= 300 Name of the attribute to maintain distance from: v_attr_name = .pad_usage Value of the attribute to maintain distance from: If v_attr_val is
set to less than zero, it is ignored. v_attr_val = -1 If v_keep_away_from_attr
= Yes is placed into the ERF file, no
thieving feature will be placed closer than v_keep_away_attr_dist
distance to any feature tagged with the attribute v_attr_name
(and v_attr_value set to desired value, if
necessary, or to -1 if the
attribute value is to be ignored). If v_keep_away_from_attr
= Yes but v_attr_name is not defined, the
attribute tagged features are ignored. If v_keep_away_from_attr
is not set to Yes, tagged features are ignored. |
