  • Once the parameters are correct select the assembly baseline marker or another subassembly marker to insert the subassembly.
NOTE: For ease of creation the subassemblies can be created on either the right or left side of the assembly baseline and then mirrored across to form the final assembly.
  • To mirror the subassembly across the assembly baseline simply select all of the subassembly > right-click > select Mirror.

NOTE: The parameters of the mirrored subassemblies are not dynamically linked. If you change a parameter value for a subassembly on one side of the assembly baseline, the change will not be applied to the opposite side.
NOTE: Use widening subassemblies to stretch design sections.
NOTE: Use Daylighting slopes to tie roadway design into existing ground.
