Adjust "End Extension"

I’m new to dynamo and I’m creating a structure from an excel that has node, bar and section information. The structure is doing fine and was creating the bars with adequate lenght, but somehow something changed and now the bars have bigger dimensions than desired. Can I adjust the End Extension option in dynamo for all the bars?

Example of the result I’m getting:

Thank you for your help!

There are the nodes Curve.ExtendEnd and ExtendStart that do exactly as you’re asking, however, the issue is likely that you have bad data or bad data management. You’d be much better off fixing the data.
