161.6 Usage
Import the post-match scenario top file and register the matcher in a match: block, overriding only the parameters you need. Any omitted parameters use the defaults listed in Configuration parameters.
The matcher is also available through the shared post-match import bundle:
$FTX/logiq/customers/base/osc/post_match_scenarios.osc$FTX/evaluate/library/scenarios/scenario_library_post_match.osc(evaluation builds).
import "$FTX/logiq/scenario_library_post_match/junctions/sut_approach_junction/sut_approach_junction_top.osc"
# The following example imports the top file and overrides one parameter:
match:
sut_approach_junction: sut.sut_approach_junction(max_distance_from_junction_start: -45m)
