The node Corridor.Baselines fail when importing baselines from the corridor having feature line as baseline. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/9/1/912e012f4bcd2fc9e3756c3eadfa4e3b60223883.png) what could be the possible solution to import such baseline? ---

Hello, Could you show us the error message and make a screenshot more large to see what is the input of your node here? ---

ok. So, there is know other way I could extract the corridor feature lines for such corridors in dynamo? ---

A workaround could be to use dynamo to create an alignment and profile from the feature line then switch the base line in program? ---

Or maybe extract them as dynamic corridor feature lines in model space and then use _Featureline.ByName_? ---

Thanks! this worked for me 🙂 I used Featureline.ByObject instead. ---

I’ll give it a try. Thanks 🙂 ---

Hi. Can you explain that? I’m in the same situation and i dont’ know how to get featurelines from the objects (corridors)… Im really new in dynamo. ---

Hi, You can use the following Nodes under Civil3DToolkit package: ![Extract Featurelines1](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/7/e/7e04d1b9e731b8cd5209e04c5a996115354af923.jpeg) ![Extract Featurelines2](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/1/2/127502d9022741243e1889574b890a6f668e6c32.jpeg) or else you can also use this node from existing default nodes: ![Extract Featurelines3](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/b/2/b271ac690803788f3864e9a876ffa5b65fd5a5a5.jpeg) ---

Hi. I know this nodes, but none of them works with featureline-based corridors…as far as i know. And how have you used the featureline.byobject node? Or did you extract the featurelines by hand before? ---

Hi. I have similiar problem. Even if I extract featureline by hand and use FeatureLine.GetFromObject I don`t know how to read start and end station of the extracted feature line and how to read feature line coordinate system. CorridorFeatureLine.CoordinateSystemByStation doesn`t accept selected feature line (even if it is Auto Corridor Feature Line).
