How can I build shorter lines base on these lines

Hi,

I hope your new to grasshopper forum. Welcome :bouquet::bouquet::bouquet:. This kind of post will consider as duplicate thread here. So next time when you’re posting a related stuff to your previous post. Post it there where you have your pervious post. No need to a create seperate post. If it’s totally new and not relevant to pervious one you can post as new post. Thank you

Cheers,
BVR
