How to modify the length of structural beam? This is my problem now with Dynamo. It´s impossible to modify this parameter. ![Capture](https://cdck-file-uploads-us1.s3.dualstack.us-west-2.amazonaws.com/flex022/uploads/dynamobim/original/2X/4/4f204eff32db5c23e8763913118dd07a8027fa58.png)

Hi,

Unfortunately, this is a read-only parameter and the only way to change the beam length is by applying a new curve through the API.

Hi,

Is there a node available to lengthen a beam ?  
Lengtening the curve line doesn’t affect the beam length.

Please do not piggy back on old threads. Start a new topic, which you have done.
