Comparing AutoCAD Civil 3D with Bentley OpenRoads for engineering design workflow

Core Development Concepts
1

Hey everyone, our company needs to switch design platforms soon since our current software support is ending. We’ve narrowed it down to two options: AutoCAD Civil 3D and Bentley OpenRoads Designer.

I have solid experience with Civil 3D but I’m completely new to OpenRoads and Bentley products in general. They don’t have much presence in our region but I know some firms do use ORD successfully for local projects.

Most online discussions about these tools end up with people saying “it depends on your clients” but that’s not our situation. We can choose whatever works best and just deliver final outputs in standard formats.

Our work includes highway design, urban streets, drainage systems, and various site development like recreational areas and industrial sites.

I’m hoping to get insights on how these platforms compare in key areas:

Surface modeling - This eats up most of our design time. We need to create precise triangulated surfaces with proper breaklines for every design element.

Corridor design capabilities - How well does ORD handle complex intersections and transitions? Can it build sophisticated cross-section templates like Civil 3D assemblies?

Performance and reliability - General software stability and response times during heavy modeling work.

Customization options - Civil 3D has great automation through Dynamo and .NET development. What are the equivalent options in OpenRoads?

Data management - Backup strategies, version tracking, and project organization features.

We’re planning to start our ORD evaluation in a few weeks so any learning resources or workflow tips would be really helpful. Thanks for any advice you can share!

What file sizes are you dealing with? I’m curious how ORD handles dense point clouds vs Civil 3D - that’s usually where performance tanks. Have you checked out Bentley’s training yet? I’ve heard the learning curve’s rough but not sure if that’s still true.

Honestly, ORD feels way more intuitive once you get past ditching AutoCAD. The corridor modeling crushes Civil 3D assemblies - you can tweak stuff without rebuilding everything. Performance has been rock solid for us, handles massive datasets without the crashes we got with Civil 3D. Just plan extra training time since the interface is completely different.

I’ve used both platforms for five years, so here’s what I’ve noticed. OpenRoads excels in parametric corridor modeling; its template library system simplifies dealing with complex multi-lane scenarios compared to Civil 3D assemblies. Surface modeling is generally faster in ORD, especially when updating multiple design surfaces. For automation, ORD’s MicroStation CONNECT Edition supports VBA and .NET customization, though the developer community isn’t as expansive as Civil 3D’s. ProjectWise integration is superior for collaboration and version control, and ORD manages large datasets effectively, but there’s a steeper learning curve if your team is accustomed to AutoCAD. Considering pilot projects alongside each other during evaluation can provide valuable insights into productivity for your specific project types.
