I’m modeling a plinth track for a metro project using Dynamo with Civil 3D . The corridor has multiple regions .Multiple regions in corrdior.dyn (64.7 KB) with chainages defined via Excel input Corridor region V.xlsx (11.7 KB)
Current Issue:
- In spiral curve sections, the corridor solids show longitudinal dimension differences:
- Outer curve edge: 10-20mm longer than center
- Inner curve edge: 10-20mm shorter than center
- Centerline: Correct length
ng)
Required Solution:
Need all edges (inner/outer/center) to maintain identical longitudinal dimensions through spirals and curves as block in above image, even slight variation for alignment is fine, region to region gap may variation from outer to inner (need not be equal).
Technical Parameters:
- Minimum curve radius: 300m
- Cant: 100mm
which paramters need to change.
