How can headwalls be added to a StormCAD file through LandXML import?
LandXML does not directly support headwalls, so we use Bentley Attributes in order for it to work.
The key is this line:<Property label="headwalldescription" value="smoothEndProjecting" />
If the value = “(UNDEFINED)” then the inlet description will be <None>
If it has a value then will create an Inlet Coefficient Set.
If the value is blank (“”) then the node will not come in as a headwall.
