I have several points located on a wall, and I want to create lines aligned with the wallโ€™s direction. I do not want to specify a length for the lines. I only want to use three inputs: start point, end point, and the wallโ€™s location (via Element.GetLocation). Please suggest the best approach. ![2025-06-19_22h05_05](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/7/7/778ca1cf81f7156b3f4aebf03837d6f4848883e8.png) ---

There are is a node called `Line.StartPoint`. I guess you need to look into _Vector_ nodes for the direction and get the length of your line. ---

As the points are on the wall, what do you need the location for? ---

It should follow the direction of the wall. ---

Ok, so if the start point is on the wall, and the end point isnโ€™tโ€ฆ. How do you expect the line to follow the direction of the wall? ---

Yes, I will place families between specific points, aligned to run along the direction of the wall. ---

I have some lines aligned with the wall, and Iโ€™m running a tracker between these lines. It works perfectly along the X-axis, but itโ€™s misaligned along the Y-axis. ---
