v_keep_away_from_attr |
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. |
