Below is a loose collection of topics and their impact on preprocessing.
Topic Create Buried Lead-ins
If one or more house connection streets are not created on the closest possible path during preprocessing, it may be due to the default setting of "createBuildingTrenches.drop.single.useStreetNames".
This option controls that when creating house connection roads the street names of connection point and possible route are matched and the HA route is created on the possible route with the same street name.
The default setting when generating the house connection streets with regard to the use of the street names of the street centerlines is "True". Set the value to "False" to turn off this matching.
