There are a number of times where you just want to get a Featurline (3D polylines) right from a profile and don’t want to deal with a corridor model or assemblies. It is sort of funny, in Land Desktop there was a convoluted method involving points and surface breaklines to accomplish such a common task. Well, not any more in Civil 3D! Civil 3D will create a Featureline directly from an alignment and profile. It has always been there, your probably may have breezed over it, like I did, for months.
After the jump learn how…
Running the command is pretty straight forward. Just create an alignment and design a profile (or sample from a surface). Run the command and select the alignment. You will be presented with the following dialog. See the image below for tips:
What may not be apparent is:
- You can make a featureline from ANY PROFILE; designed or sampled from a surface.
- You can first data-reference the alignment and profile into a new drawing and then create the featureline.
- The featureline can be DYNAMIC! to the alignment and profile.
So in keeping the above in mind. You can have an alignment and profile in FILE “A” and a featureline in FILE “B” that is dynamic to the alignment and profile. Nice eh…
