The PROJ module for road alignment is powerful but has a steep curve. Creating a long-section profile is straightforward, but the cross-section templates are less intuitive than Civil 3D’s subassemblies. For complex roundabouts, you’ll need manual overrides.
Furthermore, the road design and infrastructure modules in Covadis 17 have been optimized for the 2020 interface. Designing linear projects like highways or urban streets becomes more intuitive with dynamic cross-sections and longitudinal profiles that update in real-time as the horizontal alignment is modified. The verified compatibility ensures that the specialized object enablers and custom line types unique to Covadis are rendered correctly, preventing the common "proxy object" errors that plague unverified installations. covadis 17 autocad 2020 verified
