Hello everyone. I have 2 questions, please see attached picture.

1. How create similar effect (What I need) in Inkscape. Try using pattern along path, but can't reduce size on the end of line. And have problem with line direction, reverse path direction not helping.

2. How can i change objects placment to other side of line, without reverse path direction?

Thank you very much.

It's an interesting question, I haven't a good answer.

I hope there is a smarter way, but I would create the whole pattern with decreasing size and use pattern along path with "single, stretched".

But repeating this process for every line will be long. 

Here's a related post. The shapes were simple circles but the methods might be helpful.

Thank you so much Paddy_CAD, this helped me to find a smarter way to do it. See images :
