Multiple corridor creation using dynamo

Hello, I am currently working on a site development which consist of more than 40 roads. We have just migrated to civil3d2021 and i am fascinated about using Dynamo especially for redundant task. Normally our process are; Create existing ground surface file using survey data Create Data shortcut for the existing ground Data reference the existing ground and create the alignment, profile-views and design profiles in a separate file. Create Data shortcut for the alignment/profile. Create a fil…

Here’s an example of creating a TIN surface from a CSV file of ground survey points. Note that all of the points in the dataset are ground points, so there is no step of filtering out non-ground points. If that is the case, the filtering could be done in Dynamo, or it could be done using selections/queries to separate the points into different point groups (I think this is easier and better for documentation). Then just feed the point group name into the TIN surface creation node.

Uploading CSV files isn’t possible, so just change the .txt file extension to .csv.
