The result is text placed on the sketched lines, providing the Chainage values at that location. I’ve done some string editing to change the rounding and to add CH: as a prefix, before placing some Text in Civil 3D using the Text.Create node. The next screenshot uses the Baseline.StationOffsetByPoint node to determine the Station (Chainage) value based on a point, noting that the point it uses is the intersection point out of Geometry.Intersect in the above image. The screenshot below shows Dynamo obtaining the Corridor information, converting the Baseline to Dynamo ‘Polycurve’ geometry and then intersecting that geometry with the lines that I have sketched on the Layer called Chainage. My script works off Layer Name so I have created a Layer called Chainage. An example where this would be used on a project would be to determine the Chainage information for Pile set out.įirst, I sketch some lines in Civil 3D, ensuring that they intersect with the Alignment (shown in Red in the screenshot). You can use Dynamo to quickly determine the Alignment’s Chainage information. Quickly extract Chainage information from the Alignment (Control Line).
This is just scratching the surface of what is possible with Dynamo and Civil 3D and I can’t wait to see what other people come up with! 1. I have developed some workflows using Dynamo and Civil 3D that I hope will spark some inspiration for your teams. It provides opportunities for Bridge Drafters to extract critical design information such as Chainage information, set out information and various RL’s of elements, removing the risk of human error surrounding documentation.
From experience, introducing Revit and Dynamo into an office full of experienced AutoCAD users who have been delivering Bridges efficiently forever certainly has its challenges, which is why I think that Dynamo and Civil 3D is a combination that cannot be ignored.ĭynamo and Civil 3D provides opportunities for Bridge Designers to iterate through design options quickly, optimising their designs computationally, with improved transparency to the other project disciplines, such as the road alignment. The use of Infraworks, Revit and Dynamo in the Bridge space has enabled design teams to optimise their design, modelling and documentation processes. Most Design Managers and Digital Engineering Specialists will agree that the potential is huge in this space, but as a whole, we aren’t truly there yet.
It’s no secret that the Australian landscape is pushing hard for a BIM-centric way of delivering projects. Pair the worlds favourite CAD tool with powerful computational processing abilities and you end up with a set of tools that can revitalise current workflows for everyone in our industry. The ever familiar, popular and relevant AutoCAD interface that Civil 3D is built off will be a staple in the AEC industry for a long time to come. When I saw that the release of Civil 3D 2020 was going to introduce Dynamo, I got excited.
