Bentley Systems offers OpenRoads Designer, their civil engineering and design platform which replaces the former GEOPAK Civil Engineering Suite, InRoads, MX, and PowerCivil.
It is great when cleaning up CAD files and allowing for 3rd party add-ins. It allows you to delete used layers. It would be nice if it saved to smaller file sizes when saving as an older DWG. It is easy to scale drawings and make floor plan layouts. It would be nice if it would pick up the default units that I set for my preference when opening up a converted file from pdf.
ORD is really focused on modeling of roads infrastructure projects, but includes a few design workflows that are in other disciplines such as stormwater and drainage design and site modeling tools for developments. This is really handy because you don't need a third-party application that you have to transfer your design files over to to carry on with the project. Including LumenRT for free with ORD is by far the most helpful feature because of the visualisation capabilities which most software does not include. ORD is well-suited for what the name of the product says - designing roads. I wouldn't say there are any scenarios in road design that it is less appropriate for.
Creating linear models, since the app is based on alignment models and templates to extrude along the alignment.
Precise long section/profile along horizontal alignment. The app practically flatten the horizontal alignment for profile generation.
Template control. Though the template creation takes a bit of effort to create due to the point rulings. However when done right allows the model to be specifically modified with use of functions like super-elevation, point control, widening, parametric etc.
We like NanoCAD for what it does for us and will renew or license when the time comes. There is no question of doubt because we are very happy with it.
NanoCAD has been the best solution after using other high-priced software systems. It has all the tools I need and no need to upgrade my computer system. I run it on a Windows 11, Core i5 Computer with 8 gb of ram and integrated graphics with no issues. It does not use up much space in my ssd.
ORD is a lot faster and a lot more modern than Civil 3D even though they're essentially the same product under different names (in terms of workflows). I find that the DGN file format used by ORD is far better than the DWG file format used by C3D because DGNs can contain much more information and multiple models per file. C3D is very heavy on memorizing keyboard inputs while ORD is a much more modern interface that relies mostly on using the mouse for inputs.
